Ok So im getting ready to swap out the tranny on my 87 Renix Cherokee. I found a donor AW4, while removing the Neutral Safety Switch to clean up before the install I noticed the wiring was pretty bad so im goint to just replace the NSS. While inspecting the wiring harness that came with the donor I noticed the wiring is in pretty bad shape and has several splices in it. I may end up using the wiring currently installed on the Jeep. Was wondering if the harness is available to purchase, If so where and is there a part # available? Didnt find anything on Rock auto or other websites. Id like to replace if possible if not ill reuse what i have.


any info is greatly appreciated

What year is the donor trans? 87-90 had a different output spline count. See https://naxja.org/threads/everything...e-aw4.1053970/

Donor is from an 88 XJ so the splines should be the same as my 87

Just curious, what are you replacing the trans? If it's not shifting right, I'd suspect that hacked up wiring.

the transmission that came with the jeep when we purchased only works in reverse. Tried troubleshooting and havent been able to fix it. Found a donor from an 88 that um gonna swap over. The donor has the hacked up wiring not the one installed currently. If I cant find a replacement harness then ill rpurpose what I currently have. Dont want to use the spliced harness on the donor

Maybe it's just me but, as I understand it, you have a replacement trans, complete with harness - so what's the issue?

Mlopez

the issue is the donor's wiring is in really bad shape. I havent checked the condition of the wiring currently on the Jeep but i may reuse if I cant find a replacement

Getting the harness off the original isn't that hard, but you do have to drop the pan.

Sorry, I should've gone back to the beginning, instead of relying on my memory. However, unless you reason to believe there's an issue with your original, why even think about replacing it?
