Alternator harness help

[drcomanche]

I'm wondering if anyone can shed some light on the wires I have in a new to me harness. My current engine is a mid 90s cherokee transplant. 

 

First, it has a very long lead of 2 wires(brown or purple with a green tracer and black with a green or grey tracer, I'm partly colorblind so I they may be slightly different) extending to a connector. The wires weren't attached to the c connector, instead having the pins seemingly pulled out and tucked in the split loom. What do these go to and what positions on the c connector do they attach to?

 

Second, there's a heavy brown wire that has a rusty nut on the end. My old harness didn't have anything like this, but it connects to the c connector, so it seems important. And clue where that connects?

You need to post pics of the actual alternator and it’s plug where the wires go so we can see what type of Alt it is and what type of pin output it has

I'll grab one after work today. Found a basic pic online of it, don't know if it helps, but it's the same style.

New and old, both harnesses so you can see the difference. That extra long 2 wire is what I'm wondering about.

Do you have a pic of the actual alternator?
