- If your 2019/2020 Ram truck has AUX switches, this video will show you how to use the wiring kit that comes with the truck and how to configure the AUX switches in the Commercial Settings menu.
I want to thank Brutal_HO, IronByron, and Jimmy07 who are members of hdrams.com forums. The information they provided made this video possible.
I also authored a PDF document that covers more examples:

My truck does not have the PTO option. The wiring is slightly different for trucks with the PTO option. For example, AUX 6 controls the PTO, so it isn't available for powering other devices. - Авто та транспорт
Brother.... Thank you so much for the perfect video. Others have tried and failed at what you accomplished my friend. You made it very easy and i'm a better man for it thank you. My truck thanks you as well...😅
After fighting wiring on a '23 3500 for about an hour found you're video. It's now saved to a playlist I call "you're an idiot and need help doing this." thanks for saving my butt.
Ram didn't make this easy, that's for sure. I couldn't have figured it out without the help of multiple people on the hdrams forums, especially brutal_ho, iron byron, and jimmy07.
Ha! Ditto!
Thank you taking the time to compile the information and explain it the way you did.
Clear and straightforward.
Thanks for doing this video and PDF. The PDF really made it all seem so straight forward. Great job!
Super video! Thank you very much for taking the time and effort to help others in need.
I've referenced this video so many times. Thank you very much for putting it together.
Holy crap! The video and the supporting docs you created are wonderful. I never would have figured that out.
Outstanding video. Thx! You are very good at this, articulate, organized and concise. You even P-touched your fuses. That’s the kinda stuff I would do.
Great video, definitely one of the better how to videos I’ve run across. Thnx Brother
I know I'm late to the party but just wanted to say thank you thank you thank you for calling out the wiring and fuse locations!!! Really helped👍🏻👍🏻👏🏻👏🏻
thanks alan for the video, wished u lived closer to me cause i'm picking up my new 3500 monday and am not looking fwd to all this wiring.... its always nice to have a helper who has already been there done that!!!
Best video on anything ram related I've came across, nice work! I wired in some new lights and this video made the whole process so easy. Thanks!
Thanks for the kind words. I have some more videos that I've been working on.
Absolutely excellent explanation! I've been trying to figure this out and you just laid it right out there.
Thanks so much! This was tremendously helpful in getting power to the blunt wire in the rear of the truck so that I could run +12vdc into my bed area.
You're welcome!
Great video! I need to wire a light bar, rear work lights, 2way radio and Phone booster to my aux switches so this will come in really handy.
Thanks! I just updated the video description with a link to a PDF document that contains more examples.
i know a lineman when i see one.
Great info, just bought a 2500 and adding 5th switch panel
Dude, thank you so much. I just picked up a TRX after owning a Jeep for two years. I was expected to be able to just connect straight away to leads inside the cab like Jeep does. I guess Ram is a bit more complex. Lesson learned.
Keep up the great work man. You're a fucking legend.
Excellent video!! Extremely informative
Excellent Video! You saved me a ton of time. Much appreciated!
😀
Excellent video. Best instructional video I have seen yet. Also, that beer made me thirsty...
Great Video, best explanation I have seen yet :)
Great video thank you very much for the extra details 😀
Very helpful and detailed video honestly, Thank you for your trouble
Kudos for a job well done, I just seen those wires today while I was looking for the connection for the 12 pin video jack, that by the way is on the factory hitch….. for those of us who didn’t read the owners manual that clearly states where it was 😂
I think this gives me a solution suppling extra amps to charge the house batteries in my 5th wheel while driving. I have a residential fridge and want to run it while travelling. The current 7-pin only supplies a couple amps. Heck, I might be able to install an inverter under the hood and use the truck as a generator. Thanks for this video. Cheers!
This greatly assist in my onboard air installation thanks!
Glad it helped!
Great vid. Want to install strobe lights on my grill and want to use the factory aux. This was a great how to !!!!!!! Now I gotta ask my boss for those wires😅 2024 2500
Great video, very informative!
Great video! I can’t thank you enough!!!
This video saved my bacon. I needed to set up an Aux switch to give power to my fuel tank pump in my truck bed.
Which one did you use to get power off of?
@@brandenmulder7878 I was able to use AUX1 to switch on the power to my fuel pump in the bed of my truck. I don’t think I could have accomplished this without your UA-cam tutorial. I am sure that if I had reached out to a Chrysler dealership for help they would have struggled and it would have cost me a great deal of money. Again, many thanks.
Great video!
Excellent explanation. Looks like we share the same rig and 5th wheel
That's great! We are currently traveling all over the United States with our fifth wheel.
@@alstuart currently near Wickenberg AZ waiting for our Camp host spot to open in Oregon. Is that a 27-5L?
@@TheBuddy1939 Yes, 27-5L. We really like it.
Man, this is excellent.
@10:50, I state that I haven't found the blunt-cut wires at the rear of the truck. I eventually did find the blunt-cut wires. They terminate at the connector directly above the spare tire. More information is available in this HDRams forum post:
hdrams.com/forum/index.php?threads/aux-switch-wiring-location.337/page-2#post-26774
Great video 👍🏻👍🏻👍🏻👍🏻
Greatttt video man 👍🏻
Good video. Thanks.
Excellent video! Clear, thorough and easy to follow.
FYI, AUX5 AUX6 circuit ID's are incorrectly labeled by the factory docs in the picture of the underhood connectors. They are both labeled F605. AUX5 is F605, AUX6 is F607. Really only confusing if you're tracking the wiring diagrams to the PDC (fuse/relay).
@RJT21 Thanks. I will update that in the final version.
Great video. Did you ever end up doing a video on the other wires? If not do you know what they are for?
amazing thanks a bunch
@Alan Look above spare tire, on the driver's side; there's a wiring harness, with some holes plugged and ready for more pinned wires (Rear Battery, accessory and run) to be inserted...
Yes, it's documented in TSB 08-031-20 which states, "The upfitter auxiliary fused wires are not populated on the rear of the chassis wiring harness
equipped with Instrument Panel (IP) auxiliary switches. The wires are located on the right
side of the rear chassis cross beam, above the fifth wheel."
Please explain how to get auxiliary switch #6 to connect to rear of truck ignition power?
Thank you for putting this together. Is it safe to assume that to run some LED spot lights under the rear bumpber its probably easiest to just tap into one of the Aux connectors and run your own wire? This would avoid having to plug in the upfitter harness and do additional wiring inside the vehicle? I have a 2022 truck and thought that they had made a few changes.
I agree that it's easiest just to tap into one of the aux connectors under the hood and run a wire to the back for rear lights. I also heard that they made some changes to the 2022 model that make it , but I don't know the details.
Just ran across your video. Excellent job in describing the system. I'm thinking of ordering a 2024 Ram 2500 (too late for 2023) and the AUX switches is one of the options I want. Barring any changes made in the model years after your truck, this gives me a good idea on what can be done with this feature.
The only question I would have is, do you know if the AUX switch power comes from the primary or secondary battery on a truck equipped with the 6.7 Diesel engine?
Starting in 2021, Ram improved the AUX switch design. They added a ground wire inside the cab, and they added more passthrough wires into the cab. I don't know which battery the aux switch power comes from, but I can try to research during the next week. Here is a great video on the 2021+ AUX system.
ua-cam.com/video/6seCDodwohg/v-deo.html&feature=share8
Awesome video! Thanks so much. One quick question, I am going to wire up lights at the front of the truck using AUX1 which has a 40 amp fuse installed in the panel. Your document also shows an inline fuse to the lights themselves. Is it necessary to run the inline fuse in addition to the 40 amp in the fuse panel?
it is not necessary to run the additional fuse, but keep in mind your lights might need a fuse smaller than the 40 amp fuse. In that case, you can either replace the 40 amp fuse with a smaller one, or use the inline fuse. that's the right amperage as I demonstrated in the video
Good Video,, Thankssssssssssssssss
wow i thought i had it i have 2021 Ramm 3500 HO my truck already has all the fuses and seen pass thru left of steering column boot are they all hot feed on the connections under the hood or is there a ground because there is ground right on my firewall and 5 aux in the cab switches. I have snow chief package so there is 4 blunt cut wires above the aux connections. i have 6 switches in the cab but 8 connections under the hood are 2 of them ground connections.
The upper right port on the light gray connector is a ground. The lower right port on the light gray connector is the pass through port that goes back into the cab. That's why you have 8 ports and 6 switches.
This video is amazing! I can’t find the answer to this question but hopefully you can help me! I have a Blackvue dash cam that needs both ignition and battery power. On the grey jumper that comes in the wiring kit, can I cut the loops and use butt connectors to port 3 and 6? Or do I have to use posi-taps to keep the loops connected? Does this make sense? Thanks!!
You can cut the loops, but it will kill the power at the rear bumper. You can tap onto the loops if you want to maintain power at the rear.
After I made this video, I bought three small bus bars off Amazon. I cut the ignition loop and connected both wires to the same busbar. I cut the battery loop and connected both wires to the same bus bar. I then created a ground busbar. All three bus bars are secured underneath the floorboard carpet behind the pedals where my feet never touch. The bus bars have covers so the posts don't touch the carpet. This setup maintains ignition and battery power to the rear of the truck while also giving me ignition and battery power in the cab with a common ground. I connected my dash cam to the bus bars, and everything works great with the ability to power other devices later. I recommend you use an inline fuse for each powered device connected to a bus bar.
Alan, The best video out there. Thank you! So detailed and clear it s great. been trying to add these switches to my 2500 ram and even the dealer cannot find the proper part number for the kit. My Ram has 5 current features switches (park sensor (2), 1 air suspension, 1 tow , and another one). The aux switch module always arrives with only 4 features swith, and all the aux switches.....So I would be losing the air suspension. Would you know what part number you have in your truck?
I ordered my truck with the AUX switches installed at the factory. I don't know the part number, sorry. I believe I saw some posts on hdrams.com about adding the switches. Try this post.

AWESOME!! THANKS!! I just went through my own method of getting a battery power and ignition power source under the dash so that I can wire up stuff like a dash camera etc. I have the bigger grey connector, but of course, still in the 2023's you'd think they'd simply put a piece of paper in the bag with them with this info. DUMB on ram's part, seriously.
wow that was a very very good show and tell , thanks for this video one question where did you purchase the aux switch bank?
I bought the aux switch bank with the truck as a factory option.
Do you have part numbers for this kit and also the power distribution box under the hood as well, I want to add this to my 19 ram 1500
The part number for the wiring kit is 68398184AB. I do not know the part numbers required to install the power distribution box under the hood. I did see some discussions about retrofitting the power distribution box on HDrams.com/forum.
Question: I purchased a westin light bar for my westin bumper. A wiring harness was included which I don’t need since I have a 22 Ram. The light bar has 3 wires. Black, Red, and a smaller gauge Blue wire. What is the blue wire for?
I believe you could ignore the blue wire because they are typically attached to a rocker switch. I would connect the red wire to the output of the aux port. Connect the black wire to a ground.
@@alstuart turns out it’s a low amp second circuit for back lighting
Wish the aux switch block would work on my 2020 laramie 1500
What is the black plastic part for? Was looking for your second video covering it. But couldnt find it.
I believe it has something to do with the PTO option on the transmission, but I never did make that video. Sorry.
where do you get the negative line for the interior plug?
For an interior negative, I installed a negative bus bar high up in the footwell on the driver's side and connected it to an existing ground that was exposed near the driver door hinge. I can upload a video tomorrow showing it if you reply and say you need it.
Any ideas if a 2018 RAM 2500 uses the same wire color codes?
I do not know how the 2018 AUX system is wired, sorry.
Does anyone have the part number of the harness the truck came with my truck doesn't have it and the dealerships have no idea what I'm talking about
For my 2019, the part number for the wiring kit is 68398184AB. I believe in 2021 the part number changed because the pinouts changed a little bit.
Great video! I'm looking at wiring in a 12v cigarette lighter style plug under my rear seat for my plow light on the roof. From the video, I'm going to connect aux1 to the pass through in the cab. On the grey connector under the dash, do I connect my relay to the violet w/ yellow for the switch and the red always on for power?
I will give you a detailed answer, but first I need to know the following:
1) What is the model year of your truck?
2) Do you want to be able to turn on the plow light when the truck ignition is off?
3) What size fuse is required for the plow light?
@@alstuartit's a 2020 Ram 2500 with the aux switches installed from the factory. Id like the light to shut on and off with the ignition. It's a Buyers Products LED warning light and only draws 2 amps @12v, 24watts.
@@billgammon8734
I wouldn't install a relay because Ram has already installed relays for each of the AUX buttons. Each AUX button supports up to 40A, depending on the fuse.
I recommend the following:
1) Install the pink/brown pigtail in the upper left port #1 of the dark-gray connector under the hood.
2) Install the violet/yellow pigtail in the lower-right port #4 on the light-gray connector under the hood.
3) Splice the two pigtails together.
4) Install the gray Jumper into the port under the dashboard near the parking brake (see @10:29 in the video).
5) Splice a 12 gauge red-colored wire onto the end of the violet/yellow wire that comes out of the gray connector under the dashboard. Run the red wire to the location of the 12v lighter receptacle under the rear seat.
6) Connect an inline mini-blade fuse to the red wire BEFORE the 12v lighter receptacle. Most 12v lighter receptacles are rated for 10A, but check your 12v lighter receptacle requirements.
7) Connect the inline fuse to the positive terminal on the 12v lighter receptacle, and find a suitable ground location for the negative terminal on the 12v lighter receptacle.
8) If your plow light doesn't have its own fuse, I recommend installing a 3A inline mini-blade fuse between the 12v lighter receptacle and the light. This way, the lighter receptacle has its own 10A fuse, and the light has its own 3A fuse. This enables you to plug other devices into the 12v lighter.
9) Under the hood, there is the AUX fusebox as shown @5:01 in the video. From the factory, a 40A fuse is installed for AUX1. I recommend switching to a 20A fuse. You need a LP JCASE (low profile) fuse that is 10mm x 12mm x 16mm. In the video, I incorrectly say you need a low-profile MCASE fuse, but it is actually a low-profile JCASE fuse. On Amazon, you can get an assortment of 40 normal and low-profile JCASE fuses from the vendor named BIOFUSE for about $30.
10) Lastly, you will need to configure AUX1 button behavior in the commercial settings. The type needs to be "latching." The power source should be "ignition." The last state option should probably be "on" so you don't have to press the AUX1 button every time you start the truck.
Please let me know if this needs clarification.
Thanks,
Alan
You're absolutely awesome, man! Thank you!
Everything worked perfectly! Like in your video, my dark grey connector also was missing the little clip.
Any chance you know the part number for the upfitter kit? I can not find my kit anywhere
One of the PDF documents in the video description says the part number for the kit is 68398184. Please call a dealer and confirm.
@@alstuart thank you
Do you have a part number for this kit?
For my 2019 3500, the wiring kit part number is 68398184AB. The description is, "KIT, Auxiliary Power Distribution Center" so you can look it up for your truck year/model.
Mine clicked without taking the white clip out you got me wondering if I should check on that now, didn’t seem like it wanted to come back out
it's probably fine if it won't come back out
Can aux two be used for rock lights ?
Yes, you can configure it so one AUX button controls one set of rock lights and another button controls a different set of rock lights.
What wire spare connector are you using. 3:27
@@markruddle4252 It's one of the pigtail wires that came in the AUX wiring kit which is part number 68398184ab

@@davidbates3887 I want to do that so bad. Make a YT video of it!
@@alstuart I would like to but I am not too sure how to do that! 😆
I have a 2021 ram 3500 can’t find the rear wires. Anyone has an odea
There is a technical service bulletin (TSB) for the 2019 Ram trucks that says they forgot to install the rear wires on some trucks. It is TSB 08-031-20 which says, "The upfitter auxiliary fused wires are not populated on the rear of the chassis wiring harness equipped with Instrument Panel (IP) auxiliary switches. The wires are located on the right side of the rear chassis cross beam, above the fifth wheel." My truck suffered from this problem. I know your truck is a 2021, but maybe it has a similar problem. You could locate the wires at the rear of the truck by using a toner. Connect the toner to the upfitter wiring harness under the dashboard by the parking brake, then use the toner wand at the rear of the truck by the cross beam to find the wire that is attached to the toner.
@@alstuart thanks Alan. Been looking for them like crazy. I did notice the extra wires on the right side but didn’t think it was. Will check if they are.
