Jeep wiring is a nightmare

I recently bought an 85' CJ7 froma guy who worked me over pretty damn good. The jeep has thousands invested however, the wiring done throughout the thing is a nightmare! Underneath the dash theres so many wires hanging which are either cut or don't even go to anything at all its like you get lost at what your looking at. Because of the shorts and drains involved with all the bad wiring, the jeep only starts when it's jumped, but then runs fine until you turn it off where it completely dies again immediatley. The jeep has a late 80's corvette 350 engine along with a t-176 tranny. Problem is the guy's son i bought it from used the jeep as a damn science experiment and ended up doing things to it he didn't know how to or couldn't finish. I was told by my friendly mechanic it would cost in the thousands for labor in order for him to rewire the whole thing. I was wondering if it would take a custom wiring harness to fix the problem or does painless wiring make a harness that fits for modified jeeps. Also I'm planning on chaning the dash back to the original cj7 dash and removing all the **** he tried to add with the aftermarket one thats in it. If anyone has any advice on my situation plz help im stuck with this jeep now and couldn't do the same thing the guy who sold it to me did and beat someone for their money.

sounds like a new wiring harness starting fresh is the way to go...you'll waste hundreds of hours of your time or thousands of dollars of your money trying to sort it out otherwise... There are other wiring harness companies besides Painless though, I'd shop around a bit

1985 CJ7 Project
Phase One : 5.3L Vortec/4L60E, Moser axles for AMC20, Twin Stick'd Dana300 - Completed
Phase Two: Bedliner, Rollcage, Seats, BESRK Rear Bumper w/ tire swing, Soft Top, and a few other goodies - Mostly Complete
Phase Three: Waggy 44 front, Scout D44 Rear, 4.56's, ARB's (F/R) SOA with YJ Springs, 35x12.50x15 BFG MT - Not Even Close to beginning

Also a mostly rust-free 1970 Scout 800A That I'll get to start working on someday...

I would either build your own harness (not as hard as it sounds, CJ's only have a few circuits), or but a new one. Don't pay someone else thousands to do it for you. Heck, for $2K, I'll fly up there, put it in and fly home while making a profit!

Oh, PLEASE post a picture of the 'aftermarket' dash he has. You have peaked my interest. Thanks!

I NEED A SINGLE 15X8 MICKEY THOMPSON OR SIMILAR ALUMINUM BULLET HOLE WHEEL!!!!

Keep your eye out for harnesses on ebay. I recently bought an uncut complete engine harness for my 84 including all the computer wiring. Was complete and uncut for only 49 bucks plus shipping.

I would look at buying an Ez-wiring Harness from ebay. My wiring was a nightmare and so I bought one for about 150 and am very happy with the way everything turned out.

83 CJ, yeah its a 5

I know how you feel. I spent about 6 hours this past Saturday redoing what POs past have hacked up. I even found what looked like speaker wire spliced into some circuits. I'll be doing a new harness soon I hope.
