74 Cherokee wiring harness

Just picked up a 1974 Cherokee. It's a 1 owner with only 37,011 miles on it and it drives like new. The original owner used it to pull an airstream 2-3 times a year! Here's the problem, the guy was an electrical engineer and never fixed an electrical problem correctly, he bypassed everything in order to save a little money. I don't know why, he lived in Highland Park, TX (VERY rich neighborhood) and could have paid someone to fix it properly. Oh well. I'm now looking for a wiring harness for BOTH sides of the firewall and would like to purchase new, OEM like stuff. I've looked on the Painless site and didn't see anything there that would work, any thoughts?
Right now I have to throw old fashion blade switches that are mounted to a piece of plywood hidden in the dash to start it!

The website BJ'Soffroad offers universal 12 volt wiring harnesses in both 12 and 24 circuit configurations. I too am planning on throwing in a new wiring harnesses due to the fact my 74 has been sitting for 10 years before i bought it.

I'll give that a quick look. How do you know whether or not you would need 12 or 24 circuit harness?

I've owned a Jeep of some kind or another since 79', but this is the first FSJ for me. I don't know why I waited so long!

If you have power windows and door locks you have to order the 21 circuit. If you don't have power windows and locks, the 12 circuit is sufficient.

Yea, I kinda figured that's what the 21 circuit was for. My 74 is manual everything, makes it a little easier.
