I have been searching to no avail for a wiring diagram for the under dash wiring that comes from drivers side behind steering wheel. I just bought this ZJ and a bunch of wires are cut. I have no tachometer and the heat and ac dont turn on at all and the info center both center and above do not work. The center one flashes date and time but wont change. buttons do nothing. Overhead display is dead. Haven't taken it apart yet to see if its unplugged. Thats tomorrows project. I also have a constant ring from the door chime that doesnt stop even after engine is started. So annoying! and i have no stereo to mask it out lol. Any link to the wiring would be helpful as well as tips on resolving the issue.

Well it looks like a big part of it is staring you right in the face. I'd start with soldering and heat drinking all those broken wires back together. A Hanyes manual would have the wiring diagram you are looking for. As for online I can't help you.

Well i hooked all those back up today. Tach works but nothing else. Door chime still going off so i just yanked it. I think based on what i read the other wires are for stereo. But nit sure. Theres a solid thick baby blue wite i found cut also. Anyone know what that goes to? No clue why they would have cut all those to begin with. Nothing seems to malfuntion after reconnection

(I'm jeep Jeepin btw) sorry I was tired when i answered this last night I like figuring out electrical problems because they aren't easy some times. it sounds like you may have a short some where. Do you need help with basic procedures or are you ok with that? it would help if you can find out what the ohm specifications are for some of the parts you might be testing

I put this issue aside. i needed a new differential and driveshaft so this was least of my worries
After i hooked all those wires back up though i noticed the doors wont lock anymore, just unlock. everything else seems ok but i havnt run the vehicle in almost 2 weeks since its in pieces
