How much would you pay.

A relay is like a high-load capable switch. You generally have a common terminal (fused power from the battery), two coil terminals (when 12 volts and ground are present, one at each, then the battery power connects to the last terminal): the N.O. terminal. So the common and N.O. terminal connect when there is 12 volts going to one coil and ground to the other. We wont go into the NC terminal on some relays as it generally does not apply to fans.JerryDaugherty said:
A slightly different relay is your starter solenoid. A tiny wire comes from the ignition, through starter interlock devices, and goes to the solenoid (this is the tiny slide-on wire which is at the top of the solenoid). WHen it gets 12 volts, it connects the common and N.O. terminals (the battery lug and starter cable, respectively). Same idea - use a small switch and wire to control a relay which does the 'heavy' work. Most folks do the same with their fans.
Ok, LOL. A relay is like a switch. It gets power or ground from somewhere (just like your current switch does).
Then it as an output (like your switch does).
But it has an input to control the relay itself (so it is not always on, unlike your switch). So you can run the wire from your existing switch to the relay to control the relay and thus fan.
Just think of a relay as a another switch, but one that can handle a lot of power.

Jerry if you have a flex a lite like I do they make their own switch for it. You can ordered it from their website I think its like 10 bucks. Then you wouldnt need to find a junkyard fan. Hope that helps.
thanks guys for the info!
