1976 Jeep CJ-7 Quadra-trac automatic with 258 6 cylinder

Mods:

* AMC 304 w/ 360 intake and 2bbl carb
* TH400 automatic transmission
* Dana 20 transfer case (with granny gear)
* Dana 30 front axle w/ disc brakes
* Dana 44 rear axle w/ drum brakes
* 1995 YJ tub

My Nightmare: Wiring

I plan on using the original 1976 CJ dash and the 1995 YJ donor tub was a manual transmission.

What type of wiring harness should I buy: chassis, under dash, complete or universal? Gut it all and start from scratch or should I patch into the existing 1995 fuse box? If I gut it, how many circuits? Lastly, do I need to use the CJ steering column to make this work since it was an automatic?

My concerns are that a painless CJ harness will not take into consideration all that has been changed because I have purchased electrical gauges by Marshall, LED headlights and fog lights, an HEI distributor and electric fans to complicate the matter.

Any Ideas?

Thanks for visiting 2CarPros. I would go with the painless CJ harness seen below

https://www.painlessperformance.com/wc/10150

With this harness you can run your one wire distributor, electric fans and kick down for your th400.

The distributor will be powered by using a relay and the + coil wire to trigger it.

For the electric fans you'll need the harness below.

And for the kick down you'll need this:

Your electric gauges will use the factory wiring to cut them on and their harness for the senders.

This is going to be the easiest and most complete way to wire it as you will set it up like factory then just add these few things. i will post the factory wiring diagram for future reference.

Using the CJ column would be beneficial for ease of wiring and the shifter.

Congratulations on your success with 2CarPros!

I'm sure there were plenty of naysayers along the way; glad you didn't listen to them and that you decided to press on. Surely it hasn't been easy and I'm willing to bet there have been many sleepless nights tapping away at the keyboard just to keep the dream alive.
