Can you take off the plastic cover and see if theres any markings on the circuit board. A lot of the time you can tell what goes where, by doing this.

didnt know i could do that....not even sure if it comes of but thanks Ryan....any idea why the 4 terminals???

ryanw · January 9th, 2012, 12:13 AM

They have 4 terminals because theres a relay under that cover, and it can be set up to come on with the a/c ect.......

oh i see thanks

Is the fan pluged into another part of that box or does it use those terminal in the pic ?

CHIODI · January 9th, 2012, 12:30 AM

It just connects at those terminals only. I have the positive and negative leads hanging nearby

Hmmmm. Ya id try taking off the cover, or do some more searching for a logo, so you can look up the directions, other wise you can by pass that box and run your own relay, i can tell you how to do that.

Look close on the top of that plasic box see if there is any letters above the terminals.

The 4 terminals are 12v+, 12v-, A/C, and manual switch bypass.
