    [FONT=Verdana, Arial] I'm putting a elec-fan in my 77 chevy K5.
    This is the harness I bought.

    What I need help with is I'm not sure how to wire up a switch in place of the ignition, and what wires go where on the switch. (supply volts, on acc)

    When the switch is on the fan won't get power until the thermo switch reaches the proper temp and while the switch is off the fan won't work at all. Right?

    Also I want to wire in a indicator light so I can tell from the dash when the fan is off or on.

    Basic switch wiring is easy. It's on/off, so 12V in from one side, the other side to the relay.

    You want an indicator light so you can tell the fan is spinning, or an indicator that the switch is on?

    I want the light so I can tell when the fan is spinning, sure I won't be able to hear it over the truck

    Another question, If I wire the switch to a a souce that has constant power then the fan would still run when the truck is off, right? So I would be able to park it and the fan would run until the sensor got to a certain temp.

    Any problems doing it this way?

    Whats a good souce under the dash to tap in to?

    thanks again
