Started rewiring Jeep, made discoveries!

So I started my rewire job today. I pulled all the wiring out from under the hood, except the aftermarket stuff like the ignition, dual battery setup, and winch. When I was pulling it all out I discovered a few things.

1. I have a windshield washer fluid tank and pump! I know that doesn't sound like an amazing discovery, but I never knew I had one. It was hidden under my dual battery tray. The PO must not have used it or for whatever reason covered it up. I have no clue if the pump works, but if it does I might try and hook it all back up. I'm not sure where the hose for the fluid hooks up to though on the cowl or wherever the nozzles are.
2. The dirt and grime under my Jeep is some wicked stuff. I think NASA should look into it as a new type of heat shield or something. It took me at least 10 minutes to wash most of it off using LAVA soap, and I still haven't gotten it all. Its amazing I tells ya!
3. All of the wiring going to any light source on my Jeep has melted the insulation away and then melted the wire loom it goes through. Thankfully it didn't do too much more damage than that, although that is quite a bit of damage.

Thats about all I've discoverd so far, other than wiring is kinda a pain. I've attached a pictures of how my engine compartment looked before I started the work, and when I finish I'll post an after picture. I'm hoping to clean it up a bunch and make it nice to look at, although looks aren't everything. I also attached a picture of some of the charred wiring near the headlight switch. The switch shorted out and burned/melted everything around it.

That's a mucking fess! I think that your rewire job is a swell idea. I'm sure it will work out fine, and the Jeep will be much happier.

Re: Started rewiring Jeep, made discoveries!

Looks like you got yer work cut out for ya. I'm sure you'll come away with some good knowledge after this. And it's good to know that everything is neat and tidy, away from those moving parts and hot manifolds...
Good luck!

Re: Started rewiring Jeep, made discoveries!

Well the fire did more damage than I thought under the dash. I put the windshield down today to pull the dash off and discovered that the wires leading to the wiper motor have the insulation burned off. That wire isn't included in my new harness so I'll have to figure something out. I was thinking of just splicing a similar gauge wire in and connecting that to the wiper switch. I don't know why that wouldn't work, but I'm wondering if anyone knows what gauge wire that is? This is my first real project on my baby so I want to do it right.

Re: Started rewiring Jeep, made discoveries!

Ok, new update. I started pulling the wiring out for the tail lights and what new discovery do I make? Well the wiring is all extension cord. The PO spliced in an extension cord about 2 feet from where the rear harness hooks into the dash harness and had that leading to the rear end where he again spliced the wiring inside a conduit box so that he could get power to both rear lights. I also have two random wires that go under the passenger side of the Jeep from the front to the rear. I'm still working on tracking those down. I also learned to wear gloves when working that close to the inside of the fiberglass body. My hands itch pretty bad, but some aloe is helping.

I just wanted to share this nightmare with you all, and I am still wondering about the quesion I asked in the last post on this thread. One more question is, where is the fuel gauge sender on the gas tank? How can I get to it from under the Jeep without dropping the tank if there is a way? I really want to do this right. Thanks for the help.

Re: Started rewiring Jeep, made discoveries!

I'm sure I'll get some disagreement from the board.....but...... I usually try to wire everything I can up with 14 ga wire (as far as lights, guages etc. are concerned). I know, I know, 16 or 18 ga will work, I just like to keep things simple and keep a roll of 14 ga around for these things. My rule is simple, If I don't have a compelling reason to go bigger....I use 14 ga. This rule of thumb has worked for me for years of wiring cars, trucks and motorcycles.

Re: Started rewiring Jeep, made discoveries!

the fuel sending unit is in the tank, usually pretty close to the middle on top.

Re: Started rewiring Jeep, made discoveries!

Thats what I thought. I saw a wire coming from the top but I couldn't reach it. Its gonna be a PITA to try and hook that up. I'm still amazed at how ghetto rigged this thing was. Who honestly thinks to themselves "I need power going to those tail lights.....how about this left over extension cord and a conduit box?" AAAAARGH!!

Re: Started rewiring Jeep, made discoveries!

As long as you are re-wiring...one of the things I did for my headlights was to wire up two 12v relays. One for high beam and one for low beam. Then you simply use the dash switch to give 12V to turn the relay on instead of making it part of the headlight circuit as it was from the factory. It also made my headlights a whole lot brighter.
