My friend has an 87 GTA with a 350TPI in it. She is having major issues with overheating even after replacing the Thermostat with a 180* and a new radiator cap. We were talking about wiring in a manual fan switch to each of the fan relays. I'm at work right now otherwise I would run a search on it. Does anyone know the stock location of the relays and perhaps the relay part number that I can look for on the car? Also which wire on the relay do we hook up the switch to. I used to have it written down but have since lost that paper. Thanks in advance.

P.S. Diagrams would be appreciated if you have them.

On my 89 they were on the left side 1 right next to the raidiator and the other next to the air box, follow the wire to the fans they should go to both relays also you would need to hook up to the green wires running from the fans at least on mine it was green. You can also just follow them out 2 will go to ground the other 2 will go to the relays then to the fuse box. Make sure you fuse the fans if you dont tap in before the fuse box.
