I have a '91 s10 and i am trying to make an alternator work thats from a '99 blazer. The blazer alternator had just one single red wire in the plug. My factory '91 s10 plug has a brown wire and a pink with brown stripe wire. How do i make this work.

There is no "right" alternator. Its a 6.0 going in a '90's s10.

just hook the brown wire up to the PCM connction or do the light bulb (resister) trick

And the Lester number for the correct alternator would be???

I don't expect you to know the answer, I've read some of your other useless posts

I am running a carb so I wont have a pcm. The blazer that this alternator cam out of only had one red wire where I have two on the connector.

470ohm resistor hooked to a 12v IGN source

Do a search on "Thee alternator thread." All the info about it you could ever use

is it a CS130?
The print only shows the red wire being used

You should be able to hook the idiot light, where it normally goes to the PCM

I think its just a 100 amp from a '99 blazer. Im not sure if its a cs130. So would i even need the brown wire that is on my alternator plug? So I just hook the pink wire on my plug to the terminal "L" on the alternator?

Hook the brown wire from your harness to the new alt. Discard the pink/brown wire.

Doesnt the pink/brown wire go to the "idiot" light?

Look at the connector, the wire in pin "B" goes to the light, the service manual says it should be red, it doesn't list another wire. I looked in both 98 and 99, they're the same

Looking at your picture, there is a notch in the plug where it goes in to the alt, the wire next to it is "B"

So the brown wire in my harness is all I need? Just discard the pink/brown wire?

Yep, you just need the brown wire. The pink wire is no longer needed.
