I finished installing my switch on the intercooler pump. I just put the wire on the ground on the relay in the fuse box. I didnt cut anything. Then i simply put the switch in one of those holes on the fender.

 

 

 

Pardon my ignorance, but what does it do?

 

It is so you can turn the intercooler pump on between rounds at the track

 

interesting

 

thanks for post. much easier and safer than messing with PCM harness ground.

 

It does the same thing as grounding the white/orange wire from the PCM, you just have to know which relay to ground. Good job Latemodel.

 

Just a comment for the really ****...

It's not hard to pop the fuse box out and run the wires on the bottom of the relays. Makes it look a lot cleaner.

where does the other end of the wire go?

 

Yeah. Pics please. -Mat-

 

The other wire goes down to the pump.
You are realy just ading some wire and a switch to the loop.

Did you get a three way switch with an intermediate position so it will run at normal times.

I dont want to have to remember to turn it on everytime i start the car.

 

My setup runs the one wire from the relay to the switch then to the ground on the frame. i only used about 12 inches of wire for the whole setup.

things needed:
switch
wire 14 awg about 1 foot long.
Key must be in ON to make pump work

 

Simply grounding the pump won't turn it on, the relay or white/orange wire must be grounded.
