The whole wiring harness.

I just accidently the wiring harness. The whole thing. Is this bad?



Tomorrow and Sunday's project: make my own wiring harness for the entire Jeep to replace the hackneyed-together one the PO gifted me with. Also, my new dash goes in.

I bought 400 feet of variously colored 14ga. stranded copper gas/oil resistant wire today. I'll need some thicker wire for certain circuits, but this will get me started.

This is my dedicated help thread.

That can't be all the wiring in your jeep. I haven't pulled my harness yet, but it seems like there's miles of it. If I knew that was it, I would have done it a long time ago.

From the factory, how is the windshield sprayer jet switched on?

I put in a Summit Racing (painless knockoff) in my CJ7.. Super easy and you have like 18 circuits to use for other stuff.. Every wire has its function printed on it all the way down.. the only thing that threw me off was was the turn signals. I coudlnt get them to work right until I figured out I had the button activated for the flashers..

That looks like the engine harness and dash harness only. You're missing the front harness (headlights, parking/blinker lights) and the harness that feeds the rear (parking/brake/blinker, reverse lights, side marker lights, fuel sender, etc.).

Yes, you are absolutely right. Smartass.

You may ask yourself, "Why does my Jeep have electrical issues?," or, "Why do those lights keep flickering?"

This is why. A few prime examples of issues found throughout the harness.

Yup, that's factory duct tape!
Believe this or not, there was actually a part number for that duct tape and it was about $7 a piece when you got it from the dealership!

What are you trying to wire anyway?

Are you wanting to put the entire wiring harness back in, or just 'Critical' systems?
Will this be a 'Daily Driver'?
Or 'Off Road' only?

I REALLY need to rewire mine, but I'm lazy...
Ive rewired about everything but the dash, but I'm not completely happy with the results,
Too many restrictions using the factory arrangements,
I think I'm going to do things differently when I go after it the next time.

Maybe a 'Drop Out' fuse/breaker block so I don't have to stick my head under the dash,
And some power supply wires with some GUTS so the volt gauge doesn't bounce around when the turn signals are on!

Water proofing would be nice, since I occasionally get water in the speedo!

Hey, without that bouncing around, it'd be hard for me to tell I'd left the turn signal on sometimes! Blinker light isn't very bright, and I can't hear the click-click over the wind noise!
