    Well homie, you're in luck. Here's the correct way to connect it so it will work automatically. A switch is ok, but you only want your fan on when your engine reaches optimal heat range. Get a notepad n pen homie. I run my dual electric fans this way.
    Look at your relay and notice it has numbers next to each tab.so connect as follows
    #87 Power from battery (use an 8 gauge wire)
    #30 Connect to positive fan wire (use 8 gauge wire)
    #86 Connect either wire from temp sending unit
    #85 Connect either wire from temp sending unit
    Then start your car and watch to see that fan comes on around 185 degrees.
    Also, make sure if fan is behind radiator, that it is pulling air. If it's in front of radiator (between grill and radiator) then you'll want to reverse the positive wire and ground wire on fan. Then you'll be cool

    #85 ignition power, key on only (+)

    #86 thermal switch, temp. switch that screws into the cooling system (-)

    #87 power from the battery fused (+)

    #30 cooling fan positive power feed (+)

    This is how I've done them in the past.

    Not a temp. switch, but a relay to trigger the 2nd speed upon a/c request.

    #30 needs to go straight to the battery ,'cause it's a load carring circuit. Get it off your ignition switch. IT'S NOT SAFE. Now you can keep 85&30 together straight to the battery, and when you turn off the car if the motor is still hot the fans will stay on with the key off untill the engine cools off. DON'T FORGET TO FUSE 30 & 85.

    this way you explained how would the fan run,would it still run after car is turned off? see i tryed this way but my harness for the relay came jumped #30 to #85 didn't know there is different ways to wire it...im good with wiring but relays always confused me i dunno much about them

    The fan will turn off when you turn the key off.


    #30&#87 are the load side of the relay,one supplies voltage to the fan the other to the battery to get power.

    #85&#86 are the control side of the relay to turn the relay on/off.
