I have a 2007 Mustang GT with Whipple HO (WK-200754P) intercooled supercharger. It's been on for 2 years, and generally worked great. I've been experiencing some issues with both intercooler pump and fuel pumps. I realized that I have no wiring diagrams showing how the intercooler pump and I believe relay are connected, and therefore, have no way of testing to determine what the problem might be.

The intercooler pump was recently stuck in the "on" position even after turning off the car and removing the key. A tap on the relay seemed to fix that, but now I'm wondering if the intercooler is working at all. Wiring diagrams in information about how it is triggered would help. For instance, should it be pumping all the time when the car is on, or does the PCM call for it under load?

In any case, if you guys have wiring diagrams, they would be extremely useful as this car and system ages.

Thanks.
