Well, I've been playing with the install for the ZZP hi speed fan switch now for a few days and am getting totally frustrated.
With help from PontiacDad, I was finally able to find dash power for the switch and the two green and blue wires that go to the fan relays.
When I connected the wires, the instructions say to then cut the wires in between each of the two connections, which I did.
Now the fans don't work at all.
I'm just about ready to heave it and never buy anything again that has been designed for the GTP.
......I hate having to make any kind of repair connections. Now I will need 4 to repair the two cut wires.
I just don't understand why it doesn't work.
I know the wires are the correct ones because I rang them out with an ohm meter and I have power and ground.
