Hey guys, thanks for all the replies and the help, I think I figured out the problem, then went to Nor-Cal for 10 days and I didnt get a chance to respond.
Long story short, I think it was a combination of several things, and not having a good diagram was really confusing the hell out of me. The laminated ones from
Ebay are junk, and the ones here on Mud are from Haynes/Chiltons manuals and are better, but not great. In the end, I forked out the cash for a FSM off of
Ebay and was able to run it down in a couple of evenings of testing.
Harness is a fresh reman from coolerman, so no ghetto splices or anything like that. Fuse Panel is brand new. I had also unplugged just about everything on the heater fuse circuit. I didn't know the parking brake switch and "brakes" dash warning light were on that circuit until I got the FSM. The parking brake switch was shorting internally and at one point got hot enough to burn my hand. I replaced it and the ground to the warning light housing and so far so good.
Voltage Regulator chassis is the main ground for the lights, and it also wasnt getting a good ground on my crusty firewall, so I made a new ground and ran it to the steering gear pedestal. That seemed to fix a few of the weird issues as well.
The gauges I took apart and cleaned the pcb with isopropyl alcohol and contact cleaner. Then I replaced all the rusty nuts and washers. That fixed the weird turn signal issue I had. I also replaced the ground wire that goes to the cluster. I've been on two long test drives and so far so good, no more blown fuses so fingers crossed I am on the right track. I'm going to one by one add in things on that circuit such as the backup lights and go from there.
