I did something like this a few years back, but mine was free. I used the sensor for the CAD, but it is a smaller thread than what is in the transfer case. The vacuum switch in the TC was no longer of use, so I turned it into an adapter to use with the CAD switch. Basically take all the guts out of it until you just have the metal nipple, and drill/tap to fit the original switch from the CAD. I had to put in a couple washers to space out the original CAD switch, but it works now.
@@vipertoothpaintball5724 did they do the mod or do they still have the central axle disconnect? If they still have that, the light won’t go away until you start moving again
@@vipertoothpaintball5724 I seem to recall TJ has a true neutral shift plate in the transfer case and yj does not. I swapped one of those in my case(back when I used to flat tow) so maybe that’s why mine shuts off in N. In a stock yj when the transfer case is in neutral, the front and rear are linked as if it was in 4wd, just disconnected from the tranny if that makes sense. I believe this switch rides on that same shift plate inside the transfer case. Purely speculation but I bet that’s it. Best bet is to check jeepforum to see if anyone else asked the same question in one of those mod threads
The switch: amzn.to/3GxuGUO The connector: amzn.to/3G1SsH4 The heatshrink connectors I used: amzn.to/3vsy7Gb Get your Flawed Offroad sticker here! www.ebay.com/itm/195516877258
Lol, I remember installing my atlas… and that was all well and good, but the joy when I got the dash light working with the Atlas this weird simple elation. Lol 😂 glad to see I’m not the only one that gets excited about little things like that.
About to do this on my 87 yj, I'll be installing the cable set-up to engage the 4wd from the cab was going to use a kit that locks the front axle but I would have that wheel hop and I love how the jeep can take tight turns.
If you’re talking about a full-time locker like a lunchbox locker. Even when you disengage the posilock, it will turn in kind of weird, but at least it won’t be bound up. You will pull to the driver side.(in 4wd with locker and the posi lock disengage)
I’ve had the cad delete done on my 92 yj for awhile now. Came across this video and was yes I get my light back lol. Just did it but now I have a new problem. 4wd light is on in 2wd also. Any thoughts? I think I’d might rather have no light lol
Take the leads off the sensor, grab a multimeter. 2wd- no continuity. 4wd should have continuity or 0ish ohms. Heard many stories of the new sensors being faulty right out of box. Test that and let me know
I ordered and received the switch and the connector but the connector does not plug into the switch. Both parts numbers you have here are matching the receipt I have. Also I believe you said the switch needed an 1 1/8 socket but the switch I got is 7/8. Any help or suggestions would be much appreciated. Thanks Bill H
possible your year jeep has a different connector? I did mention 87-90 would be different. Not sure what to say on the hex size other than manufacturer differences
Sorry I had a brain fart. Id guess someone might have put the wrong switch in the packaging then? Or maybe the connector. but since you said the switch was smaller. Although I thought it was the old vacuum switch in the transfer case that was the bigger 1 1/8 size, The new switch should be smaller if Im remembering right
I enjoy all your yj contenet. Picked up a 92 last fall and already re did nost the jeep new bearings and seals. Swapped in another trans because the auto 32rh was smoked from them running 35's on 3.08 gears. I have some 4.10 for it. Keep up the hard work. Hope to do the 4wd light soon.
yeah mine had the tf999 originally(basically a non lockup 32rh) and 3.07 gears. The way I got 4.10 gears on the cheap/easy back then was I found an 8.8 in the junkyard with 4.10, and bought a dana 30 out of a 2.5 YJ that had 4.10's. THat was like 10 years ago but I ran that combo all the way up till 2021 when I did the full widths@@joshmartin7924
Nice i bought the used 32rh a yj 4.10 front axle and a tj rear 4.10 axle for 400 bucks. I call that a win. What tires dod you run on that auto setup? Im worried my 33's will scram at 55-60mph
I had 35s, it was 3k rpm at 70 IIRC but I didnt have lockup, so that'll save you a few hundred rpms. I drove it a few times on 31's it was ridiculous lol. My friend made this calculator for speed/gears/rpms, just enter your trans, gears etc and it will give you rpms for certain speeds at bottom. www.grimmjeeper.com/gears.html @@joshmartin7924
I honestly dont remember I think its just making the ground. I never probed it I just know it completes a circuit and I put the tj one in place of the YJ one and stuffed it in the case
@@TaylorBroussard-yr6cm did you bench test it before you installed it? I read a lot of the reviews on the switch saying that either the ball gets stuck or they came dead right out of the box so I made sure to test mine with a meter first and it worked fine
I honestly dont even care and its likely to go back no non operable if I switch transfer cases.... But I had the stuff on hand for over a year and it seemed like it would be a good video so I did it haha
Awesome i put a 4200 L6 vortech ( chevy trailblazer ) and 4l60e in my xj used stock 231 tcase runs excellent
Perfect video my guy. Just bought a heavily modded jeep and now i know how to do this. 👍🏻👍🏻

I was going to try that but I got rid of my dana 30 a few years ago and didnt have one on hand to try. Cool that you made it work!
You have now given me all the info I need to fix my "no 4x4 light" problem that has bothered me since I deleted center disconnect ! Thanks !!!!
It’s pretty easy, good luck!
@@FlawedOffroad so the light is still on in neutral how can I fix that? Asking for a 93 friend

I honestly don’t even care about the light, I just got the stuff to do it way back when I swapped axles and never got around to it
The parts are now saved in my Amazon list. Another project solved. Thanks for the video.
You are welcome!

Thanks for the vid and the part reference. I have the 87 and it was nice to know if might be in another spot.
You bet, thanks for checkin out the video!
Great video Now I have to do my 89...
Thanks! its not bad. On 89 its probably on the firewall like I mentioned
Good information. Thanks for producing it!

I bought a 1988 jeep Wrangler and the switch was disconnected is the switch breaking 12v DC or opening ground
I honestly dont remember I think its just making the ground. I never probed it I just know it completes a circuit and I put the tj one in place of the YJ one and stuffed it in the case
Did ya ever snip the wrong wire or chased the wrong wire. ?
Not on this project there’s only the one plug so it’s pretty straightforward
@@FlawedOffroad yeah I own a tj. Been to cold to do things on it.
Great Video! I replaced everything but the switch is not deep enough to the the TS to activate it, (95 yj 4.0) anyone else had this issue?
@@TaylorBroussard-yr6cm did you bench test it before you installed it? I read a lot of the reviews on the switch saying that either the ball gets stuck or they came dead right out of the box so I made sure to test mine with a meter first and it worked fine
Did you but that aw4 in the yj i wonder about doing that i dont they ever came stock that way
I swapped it in years ago they never came with them. It’s not worth the amount of work it takes
Maybe I should make my light work some day.
seasoned vetrans like us still need a light to tell us we are in 4wd haha. Really
I just like my stuff to work as it should when possible lol
Good stuff, one day I will give enough fucks to fix that light...I'm currently saving up.
I honestly dont even care and its likely to go back no non operable if I switch transfer cases.... But I had the stuff on hand for over a year and it seemed like it would be a good video so I did it haha
Thank you!
You're welcome!
Yeah feck Iowa. That cold wind sucked. Buchanan Co.
Yeah, it was brutal, I made this video on Christmas Eve when it was nasty cold and windy
lol@ clock comment
It’s the truth man that’s the only gauge that has never stopped working or ruined my day😂
