Hey, I've got a 91 5.0. I purchased a 16 inch electronic fan. After removing the stock fan and mounting this one, where should I ground it?Where should i run the positive wire. I would like the fan to turn on when the key is turned(same place as when radio turns on). The fan has a black and a blue wire, I assume the blue is positive? Any help or advice on ways to do this would be great.
