so i have a new serpentine system from GM Performance. i don't know how to connect my new harness to my old one. the new one has four wires and the old one had one that went to the fire wall and the other was a ground i think.

This thread will have the answer to what you need to do to wire in the Alt(you will need to extend the wiring since the ALT moves from Pass side to Drivers), you will also need to extend the AC wiring since it moves the AC compressor from driver to pass

Summit used to have the GM instructions for installing the kit but it should have come your kit

I also swapped to the GMPP serpentine kit. Mine came with the 100 amp alternator.
Splicing in the alternator pigtail reached without a problem, the A/C also reaches with some re-routing of wires. I have not connected the A/C yet, so no suggests on a pigtail.

Here is another source, although I believe the other link has this same info:
http://paceperformance.com/index.asp?PageAction=Custom&ID=650


The 'S' is the fat wire on the pigtail, looping around to the (+) terminal, just like the stock pigtail did.

good info, just remember that the 50 ohm resistor needs to be of equivalent amperage to a light bulb in the dash(3-5amp) - a dinky 1/4 amp resistor is not correct for this application

Not trying to jack this thread but I have a question. I noticed that the GM bracket 10118722 required to adapt the CS-144 to the F-Body serpentine bracket is discontinued. I still have not swapped to serpentine, but I would like to. So correct me if I am wrong, but since that part is discontinued I believe my best bet is to find a b-body doner car. Right?

depin them or cut them off... you need to run a resistor with the gauge like the drawing shows of buy the adapter with the resistor built in( its like 20.00 plus shipping)

you extend the red wire that comes from the battery to the stock alt to the new alt location, it and the S wire both bolt to the stud on the back, just ground the black battery wire to the bracket on the pass side... I had to egg out the hole on the end of the ground wire so one of the bolts that held the AC compressor would go thru the hole (IIRC)

Ok, what donor car has been used for AC hoses, or do I get custom made ones? I'm lost, its starting to get a little warm out and my pregnant wife refuses to get in my car. Is that good or bad?

later 3rd gen V8 F-body cars will have the hoses you need, there are also some either buick or olds cars that will also have the correct hoses...

Custom made hoses are not that bad, I think the kit for the hoses is like 90.00 plus getting the connections crimped at a hydrolic shop

F-body hoses will work great, but only if you changed out your condensor to an F-body one as well. Also, use an F-body accumulator for a perfect fit. I found my hoses new on Ebay.
