Alternator swap
Because the original photo got lost and no one can find it, I repost the pic....it'd be a lot nicer if I could edit this whole thread and re-insert the appropriate images...

to the black wire with the white stripe in your car...(3) the actual wires from the '80 loom...(4) and for pele, the 8 ga cable going directly to the red top Optima that will never give me any trouble!! The picture has flattened out a bit...the red wire is, in fact, not even close to the vacuum advance canisters...ignore the yellow/green wires, they're for energizing a second alternator for the stereo system that I plan on stuffing in the rex this spring. It'll keep the yellow top Optima (already in the back stow area behind the passenger seat) juiced and happy...
Hope that helps! Still haven't got around to hittin' the boneyard for spare alts and now it's too mushy to explore after the downpour...

Just out of curiosity if anyone know but anyone have an idea what terminals in the back of a 1999 Jeep Cherokee is for what? I know it's internal regulated but was trying to see which terminal is 12V trigger .

I made the switch to a second gen alt in my 80, but I replaced the fusible links with a second gen fuse block at the same time. I don't think the fusible links are reliable enough with the extra juice flowing.
Do a search, I have pics of the whole installation.
