Has anybody ever found a way to control the cooling fan, I have separated the intercooler from the engine cooling and have so far found that if you hook up the fan w.power/ground and the 12v to the controller and leave the wht/blue wire from pin 51 at the ecm disconnected, the fan runs full steem.
I am reluctant to hook anything up to the wht/blue wire witout knowing what the signal is????
I could run the wire thru a relay controlled by a temp switch in the intercooler circuit, but it would likely set the ck engine light.
Any help would be greatly appreciated.
