no i just have a fuze on the constant 12v. apparently there is a relay inside the controller. i have fan one and two grounded separtely then both are wired up to the controller separately and the ground to the controller is going off a bare metal ground to the frame and the ac spade terminal is wired right to the battery just for programming and the controller still will not respong. and if i just hit the switch for the fans only one fan will turn on and even the terminal for fan 2 as no voltage

the car is actually not running yet, it need the injectors turned down and tuned. but i talked to the techs at dif and they ran me through it and declared it a defective module and their going to test it there and then send me a new unit. i hope thats what it is

I've seen a lot of DIF fan controllers not working properly. Hell I've seen one that completely burned itself! Your better off returning it and making your own circuit with relay.

I had problems with my DIF controller twice. When I first got it, it didn't go into programming mode and then a month later when the fans would stay constantly on during the drive. Sent it back both times for it to be repaired.
