Thank you tons..
My 96 xj had a fire in the dash and half the harness or more is gone.
I grabbed a 99 xj to swap in but this is awesome bc it's about the only video that explains this process with a really good example
This was my go to info to swap an 01 4.0 into my sons 87 yj. Would have never tried without your video. THANK YOU for your effort and expertise.
This is the best video I could find! I’m planning on swapping a 4.0 into my 78 j10
This is exactly what I have been looking for to help me with my swap from a 99 XJ into my 85 CJ. Thank you for these videos
I'm dreading the wiring!
Thank you for doing these videos
Stephen,
I realize that this project didn’t make to the finish line, but these videos still remain the best source of information on swapping an OBD2 4.0 into a 4.2 YJ. Would you be willing to share more information on the subject? Preliminary wiring diagrams? Were you planning on integrating any of the gauges? Were you going to utilize the OBD2 port and it’s diagnostic functions? Thanks, Hinmaton
This helps a lot! Thanks. Starting a 89 that used to have 4.2.
Did u have problems finding a carrier barring that worked
Nice video good job 👍
It works!
Thank you!
Are you still answering questions on the engine swap
Thanks for the content. I am questioning my harness since it has no yellow red stripe. Is there a way to tell what year harness I have? Thanks!
Thanks for the info! I have a question? I bought just the engine from 96 Cherokee 4.0l for my YJ what all do I need to get/do To get it running?
Good video. QUESTION for you. I have an obd2 96 model 4.0 that I took everything wiring, sensors, fuse box, everything. Is it possible to hook everything up to where it went from factory and have it run? It’s going in an old jeep that would have no communication with the dash or any other gadgets, it needs to simply run the efi. I have the Cps and o2s already taken care of.
Hi,
Thanks for the information. I have swapped CJ7 with XJ and I want to simplify the fuse panel and wiring. Do you have any idea. How to elimine PDC and use new custom relay panel? Thanks
U did a high pressure inline fuelpump??
What about the fuel pump and the fuel lines is it inside the tank or did you swap the tank as well?
doing the same swap with a 96 xj and am curious what different about the 98 and newer
i got a 89 jeep yj 4.2 auto that im getting ready to swap the 4.0 motor trans and tcase out of a 97 grand cherokee. how much of the wiring doing i need to take from the grand cherokee? just whats under the hood or all of it? i actually have the donor vehicle.
I just bought a 1990 yj and it has the 4.2L straight 6. It has a carburetor, I want to swap it to a 4.0L but it’s fuel injected. Am I able to swap it with out converting it to a fuel injected? And if so do you know what years I can would work?
FSM?
Field service manual?
I need one for xjs thx
How hard is it to do it ? First timer
Bought an 88 yj with a 99 xj wiring harness is a mess all throughout dash, no gauges work, many dead cables I’m sure. No windshield etc etc help .. what harness would I buy ? Xj?
I have a 1990 wrangler putting a 98 4.0 but I'm stuck what about crank sensor in the bell of transmission
92 jeep yj 2.5 I'm not getting power to the coil. I have replaced many parts. Engine turns over but no fire to the coil. Any wiring suggestions to help me fix this wiring problem?? HELP ME STEPHEN PLEASE
can you tell me what you did about the fuel pressure regulator, the xj i use had the pressure regulartor in the tank
I bought the fuel pressure regulator that is the stock part for ZJs running a 4.0. I was getting 80 lbs at the rail with no regulator, regulator brought it back down to 35 ish. This is the part that i used...www.4wd.com/p/2001-Jeep-Grand-Cherokee-(WJ)-Crown-Automotive-Fuel-Filter-(None)-52100283AD/_/R-BKMN-52100283AD?emlprox=out&ppcfon=1&gp=1&tf=1&gclid=CjwKCAiA9MTQBRAREiwAzmytwxEyMc63R7UYhxlTpgGRVrv26hokJt1NJF6XiV_ZOj8-HsIgmwKWnBoCPVEQAvD_BwE
Dude! Thanks for this video. Question I just bought a 79 Jeep CJ7 with a 99 Jeep Cherokee 4.0 fuel injection. Will the wires be the same color as in your video?
Hi there, wires may be the same, I’d be very surprised if the were different. That said, my motor was out of an ‘00 which used coil pack ignition, yours is cap and rotor. Technically the harness will be different, but the colors may very well be the same.
am having the same issue dud you get it starting
I got an 84 CJ7 that I’m trying to get running. This is the exact video I needed to join the CJ with the 2003 4.0 L. Can I message you with any questions? I understand this is a little late.
Sorry for late response on my part. I’m sure you’re on the road by now, but send any questions you may have. Good to know that this works on a 2003 harness.
This helps starting a 99 in to a 84 cj could I message you if I have any questions ?
Feel free to message me, i will try to be better about responding...
What carrier barring or bushing did u use
Contact Advanced Adapters.
Hey Stephen! I'm doing the exact same swap with an 87 YJ and a 2001 XJ donor. I have everything wired up and spliced according to your video. I'm having an issue getting it started. The motor will turn and I have a temp setup for the fuel pump and am getting 43 PSI at the rail, but it appears I have no spark. All grounds are solid. Any advice? I feel like im missing something simple. The CPS checks out, tearing my hair out here so any help would be greatly appreciated, thanks.
Crank sensor
@@mattperry1449 I thought so too but the CPS is giving the right readings, unless I'm testing it wrong
@@taylorcoulson4242 you know more than me sounds like. Idk what the CPS is? I replaced every electrical part on mine one time. Then someone laughed and told me about the crank sensor. I replaced it. Started right up. Then went bad again within. A month
Never mind. I'm a dipshit. I know what it is
Is there a way I could get a hold of you have a few questions.
Sure...can't post the questions here?
Could I get your email or a way to get ahold of you, I'd like to talk to you about some wiring on the XJ swapping motors Thanks
Hi there, happy to answer questions via UA-cam...feel free to post here
