well, after doing some research on wiring, my conclusions are...
A. Frustrated on the lack of wiring diagrams online for Jeep in general
B. I have been searching for decent wiring diagrams since I was 15, its like Jeep never wrote this stuff down in the 90s
C. Even FSM manuals have crappy Diagrams
Im just going to have to get all the wiring harnesses I can on a workbench and figure it out.
I also decided to buy an un-cut under dash and engine wiring harness for a newer YJ, Not neccessary for this swap by any means, but my carb'ed YJ harness is cut up, and does not have any provisions for A/C.
The fuel injected harness has all the A/C hookups, fuses ect that should make this easier. It also has the "Power Distribution" box, that I am hoping to utilize to re-wire everything to make my 4BT seem more "Factory"
The power distribution box has fuses and relays that I can re-assign to my fuel shut off solenoid, Vacuum pump, blah blah blah.
Now I am rambling....
Basically, I think the best way to do this is to get all the wiring harnesses I can together, and slowly cut out what I dont need, and wire in what I want....
Any recommendations on a manual that has good wiring diagrams? Everyone says Chiltons, or any number of those manuals at autozone, but their diagrams are very generic.
