Sweet, thanks guys. What about the green and black wire shown in the second picture?

I tried to find out, but since my truck is a 70 it's a bit different. I have a feeling it may be for emission controls but I'm not sure, sorry.

Green wire looks like the temp sender wire. As for the black one, you'll have to trace it back and see where it goes. If it goes into the bulkhead connector, post a pic of where and we can figure it out from there. I would also trace the green one to make sure it goes to the bulkhead too, it's just with that aftermarket wire loom you never know what a previous owner could have put in there.

Mine had a TCS (transmission controlled spark) module but most of the components were missing. It came out about where you were talking about. I redid my wiring and eliminated this stuff.
