- Today at Ugly Truck, we're talking about everyone's favorite LS swap topic: WIRING. Whether you're swapping a 1985 Chevy truck or a Jaguar, it's important to understand how these circuits work. We discuss 12 volt batteries, how power is distributed, how relays work, and how it all comes together to start and run the engine. We also talk about wiring diagrams, how to read them, and deciding which circuits you'll need to power up. Every project is different, so you'll need to know the specifics of your engine, transmission and harness, as well as the vehicle it's going into. But with a little know-how and the right wiring diagrams, it can be done. Hopefully this video gives you the info you need to jump into it!
Thanks for watching! Stay tuned for the next video, where we'll be tackling the wiring on the 85 C10 5.3 project! Click here to get caught up on the swap! • 1985 Chevy C10 - LS SW...

👋👋👋 Check out the 85 C10 swap here! Exhaust, fuel system, wiring, and more! 😁 ua-cam.com/play/PL3Xf8yWArPC4Qda-Lj78McLIQjdtHqjyY.html
so far the best LS swap videos, thank you for sharing your knowledge
Thanks for watching! We're just getting started, and we've got a lot more videos planned! 😁
I want to thank you two for going so in-depth with explaining your process! I am doing a LS swap into my 1946 Chevy truck and am using a 2001 suburban 6.0/ 4L80 donor. This truck has absolutely no wiring at the moment so I will be creating all the circuits myself. What fuse blocks are you using and connector set ? I love the simplicity (at least you made it seem that way) of the ‘85 wiring.
Glad we could help! I'll put the links to the fuse blocks and connectors below. Check out this video too... It's specific to this 85 C10 and a 5.3/4L60E, but it will show you how we set up the fuses and relays for each circuit. ua-cam.com/video/d8mcQl-rYr4/v-deo.html Just let us know if you run into any snags, and we'll do our best to help you out!

Wow great job explaining everything today.
Great camera work Emily!
Thanks so much, Mc! We appreciate you tuning in! --Emily and Jerry
Great videos really helpful I've got a 73 c10 about to put a 2004 vortech in it u make it look so easy hopefully everything goes good with my swap too
Glad to hear our videos have been helpful. Best of luck with your project! We have a 78 C10 coming up soon. Thanks for watching!
Thanks for that lesson!
Nice information I love your channel.
We appreciate it Don. Jerry
Great video ! I bought mine from howell wiring the other one holley terminator max
Thanks for watching! The Terminator Max sounds like a sweet set up, but probably overkill for this daily driver. But it gives me some ideas for an upcoming project... 🤔😁
Great Info Thanks
Thanks for watching!
15:00 great info!
Thanks Lucas! We appreciate you tuning in!
thank you guys so much love your youtoube channel so much info …god bless you. and famly
Thanks so much! We appreciate you watching our stuff! 👋 --Emily and Jerry
Hi guys thanks for the great videos just watched the 63 4x4 nice truck. I'm doing a 79 corvette 5.3 4l60e and wanted to know how do you wire the TCC disconnect and where do you wire in the OBDII port if you don't have the harness for the cab
What is your donor motor and is it fly by wire or cable operated?
How can I wire the low oil light up to work in 72 Chev swap to work?
Awesome channel! Very informative! I am currently swapping an LM7, freshly machined, into my 86 Chevy P30 Grumman Food Truck. My confusion with all this wiring, I feel like I'm going to have issues with electrical. The LS will be mated to the trucks' original TH400. Will I need anything for the Trans and PCM to talk to each other? Also, mostly everything are new OE parts that I've ordered, such as a Suburban radiator. I would like to convert to E-fans. Watched your awesome video on it. I assume I'll need the brain flashed to accommodate for the conversion. Do you have any advice on tackling all this? Thanks and keep up the great and educational vids!!!
If your using the OEM computer and harness. The computer and harness are already set up for the electric cooling fans. You may want to have the computer programmed to turn the cooling fans on at a cooler setting. I run 180 degree thermostats and let the programmer know that and he adjusts it accordingly. For the transmission you will just need to have a vss signal going to your pcm. There are plenty of adapters out there to convert from mechanical to electronic. Sounds like a cool truck. Keep us posted. Thanks Jerry
Can you make a video explaining the bulkhead wiring on 1987 R10. I'm stumped on wiring up my PSI stand alone wiring harness with PSI ECU.
Hey Raul. What parts of the harness are you having trouble with. We do have some of our recent videos that talk about the bulkhead going into the interior fuse box but they mostly talk about the gauges and getting power to that interior. If you have some specific questions on that PSI I could try to help. Jerry
How did you power up the bosses truck since the coil wire is a resistor wire with points type system was that lower voltage from that wire enough voltage to switch a relay on those had "R"and"S" wires from starter to send 12volt to the coil at crank
That is a great question. When we first bought that truck, it had a 307 in it. We put a 350 in it and added a HEI ignition. At that time I would have ran a new wire from the connector at the firewall to replace that resistor wire. That resistor wire would definitely trigger a relay but much simpler just to throw a new non resistor wire in that plug. New connectors for those old plugs are readily available and they pull out of the plug fairly easily. Thanks Jerry
What fuel pump did you use thanks. I want to swap 5.3 to my 83 statiom wagon
I used a Holley pump on the last couple that I have done. Here is a link to the one I bought. Thanks www.summitracing.com/parts/sne-19-369
Decided to go the holley route but overlooked that that harnesses dosent control the starter or alternator curious as to what i need to do to tie them together
Hello Lucas. You would end up having to run the wiring for the starter similar to the way the original vehicles wiring was. Power to the starter and then the wire to the starter solenoid. The alternator would just be wired independent from your harness. How it is wired would depend on what your donor was. Jerry
@UglyTruckExperience hoping that the holley alternator harness will solve that issue I think I've got the starter figured out. Got power wire and wire from neutral safety switch
Where do you buy your wiring diagrams from? I have a 2007 5.3.
Hi James, we use AllData for our shop program but we do pay a monthly fee. Check out AllData DIY. It gives you all the service info and diagrams for one specific vehicle, which is perfect for a swap. Thanks for watching and commenting. Emily and Jerry
Need help. I have a 1994 truck 2006 5.3. swapped everything from donor truck. Getting lots of transmission codes. Is there something I missed. Love your videos please help.
Hi Barry! Are you using the 2006 4L60E that came with the donor? What codes are you getting? Does it seem to shift ok? Just need some more details. We appreciate you watching our stuff! --Emily and Jerry
@@UglyTruckExperience I found one of your videos. I didn't have it wired up. No key power so I hooked it up to the same ign pink wire as the engine. Seems to be ok now. Without your videos I would have no idea what to do. Thank you for everything.
Thanks Barry. We appreciate it. Jerry
Looking to put an LS engine into my 96 K1500 Z71, 4.3, 4L60. What do you charge for the swap?
They are all different, but the last one that left was right at 13,500. Parts and labor out the door. Thanks Jerry
Hi I would like to know how can you make original speedometer work
Check out this video! We just installed a Dakota Digital speedometer adapter in our LS swapped 70 C10. ua-cam.com/video/hLqXYWG_WhY/v-deo.html
Hey there where can I buy one of those wiring diagrams?? Lmk thanks
Are you looking for a wiring diagram for your later donor motor or a diagram for what you are swapping into?
Thanks for the help , where you guys located at?
Thanks for watching! We're in SW Missouri. 👍
@@UglyTruckExperience that’s to bad , looking for someone to do a LS swap for my chevelle
@@UglyTruckExperience I’m in Florida
How about a video on different types of mechanics?
I like that idea! We'll do some brainstorming... We'd love to see more young people pursue a career in this industry, and I think showcasing different parts of the automotive/transportation field would be a great place to start!
Where can I get the diagrams? Using an 06 Denali with a 6.0L for a swap, would like to find the diagram papers to print our
Check out Alldata DIY. It is designed for projects like that. It is very reasonably priced and gives you every bit of info that is out there for the 06 Denali. That is where we get our wiring diagrams with our shop program. If you try it out, let us know what you think. Thanks
@@UglyTruckExperience I did get it and it seems amazing, couldn’t find a decent schematic for my 86 C10 yet
Classic truck has a full diagram for that truck. I just bought one last week. They are very hard to read but that is how they were in the 80's.
@@UglyTruckExperience you’re the best! Yea the one I found was hard to read but legible. I just wish it was on larger paper cuz I had to print it. I’ll definitely check out classic truck!
What part of Mo are you in ?

Electron flow is negative to positive not positive to negative
You are correct. Thanks for your comment.
Who makes the relays you use i have led driving light thru a relay and they are 30 amp relays im only getting two months use out of them till they leak white junk out them
Here's a link to the relays we use. Thanks for watching! www.amazon.com/gp/product/B011H0MSPQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
You should offer your wiring print outs for sale to people that dont have computer program you have for a price i would buy one for my 46 1/2 ton swap
I mean the pin out schematic from the donor vehicle/computer
I wish we could do that, but most of these shop programs specifically say "Do not distribute." Check out AllDataDIY... We've never used it, but the pricing looks reasonable. www.alldatadiy.com/contact/faq.html
Battery explanation is a little off. Charge flows from negative to positive. The water analog is incorrect: Voltage is anagolous to the system water pressure. Current is analogous to the flow volume (bigger/smaller hose). Also Power is (Volts * Amps) and measured in Watts or Horsepower (750 W ~ 1HP). The reason wires heat up is because they have resistance. And like the light filament, wire will glow red hot right before it burns itself out because it is not in a vacuume like a lamp filament is. The reason a filament in a vacuume does not typically burn out is because its resistance increases with the current going thru it, so it reaches a steady state of glowing but not buring out. Filament bulbs typically burn out when they are cold (i.e. just when they are turned on) because of the low resistance allows way more current to flow (inrush current) than when burning in steady state. Of course, none of this changes the operational information you expounded upon. What makes car lamp wiring so involved and complex is that bulbs can be single or dual filament and share various current paths. I'm currently tearing my hair out over all-bulbs-test-fine but getting double-rate bliking when running lights on and dimly bliking when brakes applied. BTW, the "Grounding PCM" is technically called "active low switching".
