you could wire it into the ignition power. or if you want to be ghetto you could run it out of the fuse box from any fuse you choose that gives power only when key is "ON" position.

another way is to run a wire from the battery and use a toggle switch to control it. the only downside to that is that you may drain your battery down if you forget to turn it off.

where can you wire it up so it only turns on at a certain temperature what else would you need?

If you want to be ghetto you can buy a kit that is for thermo's and it has a temp sensor that slides into your radiator hose and you clamp the hose down over it.It has a temp switch you can adjust to your needs and is basic which is what it sounds like you need. Even comes with a wiring diagram.:1zhelp:

the cheapest way to wire up an electric fan is to use a generic 85-86 87-30 relay and connect it to a 12v ignition wire and also your e-fan. that way the fan comes on whenever you turn the key on.

connect 12v switched power to 85, ground to 86, ground to 87, and e-fan ground wire to 30. Wire the positive of the e-fan directly to the battery.

Should only cost a few bucks for this relay and its available anywhere.

Hope this helps :)

if you use the old fan wires... meaning the small fan off to the right side of the radiator(looking from the front of vehicle)... it wont work ... as that fan is only commanded on when the a/c is running

I don't have AC in my car (therefore, never use it) but the electric fans come on at about 205F (on my aftermarket water temp gauge). I don't know if that's early enough or not for fans to come on, but I was contemplating doing electric fans just off those plugs.
