There are 3 one is ground. One is power.. ths other little wire is what? I thought there would be a high low on it. But im kinda stumped. The 3rd wire is smaller also. I am doing relays for my holley system it will fire the fans

Marauder fans only have two wires that I know of, unless your talking about the controller? If so, the smaller one comes from the PCM.

The speed is controlled by pulses from the PCM.

Doubtful. You may have to change to a different fan. I believe the Mark 8 fan will do what you want, and it has been reported to cool better than the MM fan too.

I used a Mishimoto 15" puller and ran it off of the controller. Works great

Does the mark 8 bolt up?
