Re: Fan Relay Wiring
86 is your power source for the relay. If you want the fan to run after the key is turned off then hook 86 to a constant 12v. If you want the fan to shut off with the key, then hook 86 to a switched 12v source. 87 goes to the positive lead from the fan. 30 goes to the fan switch. 85 is the ground for the relay. This is exactly how I have mine hooked up.
