    Hi all,
    Is there a 12V ignition wire in the engine bay. I just need to find one that gets power only when the car is on or the key is in 1st or 2nd position. This is for my trans cooler fan by the way. Thanks!

    -Matt

    Just to reiterate what @jbrandt said....

    Only use the add-a-circuit to trigger a Relay. DO NOT use it to power the fan directly.

    I would think that as long as your combined amperage doesn't overload the circuit, it would be fine. But now that I think of it, a fan would probably overload just about all the circuits in the fusebox anyway...

    I was thinking about using this Derale 16763 Electric Fan Relay Wire Harness

    How would I wire that?

    Instead of lights, your fan.
