Jeep Mutt

Ok guys, I am having an extremely frustrating problem, I am doing a build that started out as an 80 CJ7 Golden Eagle, and ended with a ton of problems which had us piecing together a Jeep from what ever we could locate. We now have a frame, body, and suspension from a 97 TJ 4.0; a 4.2L motor from an 80 golden Eagle, Automatic transmission and 231 transfer case from a 93 YJ. The problem that I am running into is in the wiring, I don't know where to start when looking for a computer that will run all of these different parts. What is the most important part that requires a specific computer? is there any specific module that I could use to run these parts. Does anyone know where I could retrieve diagrams that would help me with each of these problems. Do I even need a computer to run any of this stuff if I wire in sensors. I really need some help guys, any info you guys can provide would help.

You do not need a computer to run anything mentioned above. 93 YJ assuming came with 3 speed TF999. I can make up a simple schematic for you that'll run your 4.2L

Man that would be awesome. What if I were to use everything in the dash, ac, and other components from the TJ. The motor, trans, and trans case are the only things not from the TJ. I'm worried more about what wiring harness I should use, I have the one from the cj7 motor and the internal components to the 97. Where would I need to make changes here?

You can use dash components from TJ using TJ wiring harness to save time. As far as your motor harness goes, keep that separate and make your own according to my schematic. Give me a day or two to make it, super busy in the shop lately

CJ7 harness is going to have so much crap you don't need, all it's going to do is confuse you.

I just thought of something that may help you. If you tear into your CJ7 harness you can rip off about 80% and set it aside. Use whatever wires you need to make something like this:


This is an old one I threw together really quick for my tech to install the Howell kit. This will work for your 4.2L without running a computer.

Ignore orange and purple leads coming out of starter sol. They're Howell specific

What exactly is Howell specifics? Just curious. Hey man that would help me out a lot, I have been looking for diagrams like this. I have a few wiring harnesses from a number of different vehicles. I was panning on looking for some type of deal like you are talking about drawing up and doing it all from what I have. I do have new wire because I know there are places that I will have to replace some wire.
