I was wondering if anyone could lead me in the right direction, How to set-up my electric fan to a toggle switch? which wires go where?

Nope, Its got 2 screw pins, I am assuming power in power return? I dont see a ground pin screw. Dont know?

then just run a wire from the possitive terminal to a switch in the car. from there run a wire to the possitive wire on the fan and then hooked the negative fan wire to a good ground. most people use a thermometer so that the fan turns on automatically

Kool I will try that out, I havent had much experince with toggle switches, I am pretty sure the switch just acts as a loop, Just like house light switch does.

its the same. i love doing engine electrical....it just takes time before you get comfortable with it

yeah to that, the switch should always be in the hot wire and will not have a ground wire coming from it as all it does is interrupt the current flow when it is in the off position. The fan motor itself does have to have a good ground connection though.

Food for thought - fans draw a LOT of current, it's partially my fault but I had a toggle switch, I had my fans on all the time and I was wasting alternators left and right.

But, I believe Mustang's have a much higher amp than my sbc did.
