Resolved Question:

My 1991 S10 Blazer CS130 alternator has 2 wires, 1 brown and 1 yellow/black. They have been cut so, I don't know where they should be connected on the alternator. I don't want to guess and risk destroying a new alternator.

No, it had an aftermarket plug and both wires are gray. They are the 2 middle wires out of 4 connections.

in the image im posting you can see the plug next to the generator the brown is clearly marked this on has a pink and black but your yelloow will go in that location

I have that diagram already from ALLDATA but it doesn't really help because it has circiut numbers instead of connector letters. The letters should be L and I or L and F and I think that diagram is for a SI alternator instead of a CS alternator. I'm not sure

if you look at the plug with the wires pointing towards you and the retaining clip to your left hand your brown wire will be the top
