I want to try and install my Mark VIII fan today on my Stang. I am eventually gonna get one of those DC Control systems but for right now I am going to run a manuel switch. Can anyone tell me how to do this. I know a need a relay and an in-line fuse. But what are the three wires? THere is a blue, a black with red stripe, and all black.

Can anyone clue me in to what is what? My first thought was that the black with red was the pos. and the all black was ground. But what is the blue wire? Is that for High setting or low setting?

Also how do I hook this up to a relay. What wire goes where? And how big of a fuse should go between the relay and the switch?

5.0 MPG does your fan have three wires too? A black, black/red, and a blue? If so all the diagrams that I have found don't tell you what is what and none of them even use a third wire. I don't really want to buy an adjustable temp control. I want mine to be on the high setting all the time. And I'm just gonna do a manuel switch. Makes it a lot easier on me. I only really need it when I'm at a stop light so I don't have a problem flicking it on and off when I'm at a long light.
