I got my electric fan, and i'm trying to decide how to wire it. If I were to just wire the ground to a ground, and the power to a 12v wire that gets power while key is on, and have it running all the time when the car is on, would that be alright? Any other suggestions? I'd like to avoid having it run to a switch, if possible. But, I'm considering running the electric fan, my fuel pump, and my ignition box, all to a switch inside the car. I could turn it into a killswitch, too. Get into the car, hit the switch.. fuel pump, MSD box and fan all come on, turn the car off and flip the switch and they all turn off, and my car won't start until it's flipped back on. I wouldn't even need to cut the ignition wire to make it a kill switch - the car won't start if the fuel pump isn't on Suggestions?
