Jeep wiring harness OVERdone right (or so I hope)

Hey guys,
In the coming months I plan on starting the tear down of my jeep. After sanding/painting the frame/tub, I plan to overhaul the wiring.
The idea is to rewire it from end to end. I already have removed all of the unnecessary wiring. Next step will be to replace what is left.
My plan involves using circuit breakers like http://tinyurl.com/pv6wqpx , and or http://tinyurl.com/ozo22bw . I will then pigtail wiring into
cannon plugs (such as the tail lights) using http://tinyurl.com/p264o4g . Finishing up by labeling all wiring at the connections and zip tying
the bundles.

Anyone else rewire an entire CJ have any advice going into this? Anything odd/strange that you wish you knew ahead of time?

If this is anything anyone is interested in I can post progress pictures as I go as well as parts used.
Wish me luck!

The Forum search is pretty useless, if you use Google search for "wiring a Jeep CJ7" you will find helpful articles etc. Here is one good one from THE HAMMER

Good luck

Fill out your profile. It is most helpful to know exactly what you are working on. Wiring changed from year to year.

Go buy a Jeep manual that has a wiring diagram. Took mine to a print shop and had them blow it up as much as possible so I could read it.

Those are nice circuit breakers but they could take on dust etc. and cause problems. I would keep it simple with a good fuse block, lighter and will take more abuse from water, dirt, etc.

Some of the most troublesome spots are the firewall connector and the steering column wiring. If you want reliability I spend my time there and try to upgrade those areas with better connectors.

If it is all wired well the fuses should never blow.

I ran across a Ford pickup in the salvage yard the other day and it had an intact box with fuses and relays in it that I want to go back for an use in my CJ. I believe it was a late 90s model.

Cj CJ-5 rewire

I rewired my entire 1975 CJ-5 during my rebuild. Most helpful was having the OEM manual to reference back to. I also covered all splices (soldered, not crimped) with marine grade heat shrink (has glue inside). This waterproofed these connections as I saw a lot of corrosion at these points when I did my deinstall. I had to reuse the steering column connector as I did not find a suitable substitute.

I also went into Auto Cad and drew out the entire diagram, similar to what was in the manual, so I would know what went where in future years. It has come in handy.
