Manual Fan Switch
Can anyone give me the link or diagram on how i'm supposed to hook up a manual fan swith in my car. I have the three prong switch with connections labeled (from left to right) 'power', 'acc', 'ground'. The relay is labeled WJ1208, and below that is CONT: 30A 14VDC and COIL: 12VDC. I also got the harness wires with that, is there anything else I need other than gauged wire? Thanks in advance. :seeya

The main fan relay is on the rear of the left inner fender well. The activation comes from the ECM through the yel/grn wire to that relay.
Simply splice a wire into that yel/grn wire and run it to one terminal of the switch. From the other switch terminal run a wire to ground. When the switch closes this ground path for the relay the main fan will come on when the ignition switch is on.

It's hard to describe w/o a diaghram, but the switch is wired in series w/ the coil side of the relay. Form there it gets connected to a 12v source, and the other side to GND. The Common side of the relay contact, gets wired to the fan wires. The NO (Normally Open) contact of the relay get wired to a battery source. This whole side of the ckt should be at least 14AWG wire.
Good luck
