Firewall Pinouts
I just finished completely re-wiring my engine comp. harness to eliminate the ecu and everything extra going from v6 to carb'd 400. I need to double check myself as i didn't have reliable schematics and did the ol' wire trace to be sure. I would like at least these two connector pinouts (names copied from someone elses post, i think they're right) anything extra will be accepted. I need them for a 89 v6 or anything else that has the same pinouts.
1.) C100: located on the firewall, drivers side, near the brake booster. Big plastic 2-piece rectangular block
2.) C207: located inside the car, passenger side footwell, white/clear plastic 2-row connector.
Thanks, I want to get this thing buttoned up over the holiday weekend.
Edit: i need the engine comp. side of c100 mainly. i eliminated c207, just want to doublecheck i won't miss anything.

alright alright, I'm glad i got those, it turns out i removed my fp-fan hot lead when i removed the computer. It was the only lead that went through the passenger side of the harness that i still need. I re-wired that through pin G4 of C100. It's all soldered/zip tied and ready to loom. Thanks alot for the diagrams. Do you happen to have the pinouts for the body plug on the passenger side? that's the one I meant instead of 207, but I needed that one anyway.

oh, I didn't notice that. Haha I didn't even look at it that close. oh well, i'm pretty sure i got it all right, and didn't remove anything else that i needed. Everything that goes through right there went to the ecu, except for that hot fan lead. i'll plug the battery back in tomorrow and test everything out.

ACC Fuse Short
Alright, new problem. when i added a harness for the radio( stock one was ripped out) I got continuity from the orang power to ground. I assumed it was the frayed ends from where they removed the harness, but it's not. I unplugged the int. lights, the radio, and the power lock relay one at a time and still got continuity from acc to ground. finally I unplugged a random connector under the driver side dash behind the hood pull. now I can hook up the batt. and my dome, int, radio,taillights, and headlights work. i am going out now to test out power locks( which I have a suspicion don't work) and power windows. My gauge lights don't come on, but this might be unrelated dirty contacts. The connector had for pin locations-one orange, orange/black, Pink, and one empty. Anyone know off the top of their head what this is for? oh yeah and sorry for the long post

Figured it out, the pink goes to my windows, the orange/black goes to my door lock relay, and my orange goes to my door lock switch. whitch one would be the culprit? bad door lock selenoid? And my gauges were just a bad connection, so this is the only current problem.
EDIT: Oops, it was just the cig lighter, everything works fine now. Thanks
