I now understand why all of you procharger guys says the instruction sucks.....

Ground the green and white wires on the fan relays on the firewall........ this could misslead alot of people if you dont know what youre doing......

But what is the purpose of this?

havent found my el.schematics yet.........

 

I think it is to make the fan runs at all times when the car is on, b/c the car will run a little hotter w/ the Procharger and intercooler.

 

Stoc roc is right it makes the fans run all the time to keep it cooler. The intercooler restrictes the air flow ALOT! I had problems at first with my temp. in the summer I run water with water wetter. It runs cooler with that set up

here is a diagram

the fans would all the time now run when the relays get power and thats when the car is on..
