Alright, i know how to wire up the electric fan, but i just had a little question. I wired up my MSD 6A box the other day, and it uses completely different wires going to my coil. Could i use my old coil positive wire to wire up the fan to switched 12 volt? Or will that make my car stay running when i turn the key off?

don't know how you wire up your msd but it still should be using the switched 12v source

Its still on a switched 12v, i just didnt explain that good enough. The diagram on the msd said to run the white/black to the original coil + and - wires, and run the orange and black to the coil. Right? But I wired the fan to the original coil + as well. Which makes the stock tach go crazy when i turn the car off.

if using msd ignition with a factory tach..you'll need to purchase part #8920 from msd called a tac adapter or suffer the effects you have

I used the 12v key on source for the wiper motor and it worked great. its the big red wire on the front wire harness of the wiper motor.

My dad was saying something about a wire on the wiper motor, but i didnt just want to start cutting up wires without knowing which one exactly. Thanks
