Re: Another project for my 1990 Wrangler YJ
The harness comes apart into sections at the back of the fuse panel.
You undo the center bolt and the section plugs come out. One will be
for the engine harness, one for the front clip light harness inside the
engine bay. The other harness pieces come off inside at the same time.
Again one piece for the dash and one piece for the body and it's lights.
Places like painless wiring sell kits: http://www.painlesswiring.com/
They only list up to the 86 CJ wiring, but the underhood harness for an
86 CJ7 is 'really' close to the under hood wiring of a 1990 YJ with the
258 in it.
Other places sell them also.
You might want to get a Haynes CJ manual also. It's wiring diagrams are
right on for the later CJ's and I have used it to rewire a couple YJ's
after fires caused by shorts also. The YJ book is crap for the 258 or
4.2 engine bay setup.

Re: Another project for my 1990 Wrangler YJ
Mike,
Thanks again for the input. I've noticed the yj info isn't the
greatest and will look into the cj stuff if its close and will work.
I'm hoping to find some wiring harnesses for the yj from someone or a
junkyard instead of having to purchase a full new one or ones. If I
understand correctly there is the main wiring harness, the light
harness and the radio/dash harness. Is that correct or am I missing
one?
Thanks again and I am sorry to sound stupid.

Re: Another project for my 1990 Wrangler YJ
The body tub has it's own harness chunk, same as the engine.
The CJ book is the best one for the pre 91 YJ's because they are close
to the CJ design. After that, DC started messing with them.
The wiring under the hood is almost identical except some of the
pollution crap and that depends on where the Jeep was sold.
