GETAGUN

I want to manually override the engine fan and heat exchanger water pump relays. Does anyone have a wiring schematic or know which relays run them.

Looking to help cool car between runs

Slow Poke

I have not found any information on the coolant fan wiring diagram either. I am working with Casper Electronics and tried a prototype C6 Hi/Lo fan controller unit and it did not work at all. I am looking for a used C7 fan to bench test and come up with an override solution. Anyone with a service manual post up the cooling fan wiring diagram for me?

The intercooler pump can be turned on by the HP Tuner scanner while the engine is off. This is the only way I have found so far. The fan controls in HPT scanner do not work on the C7 fan either.

I will post results if a solution is found.
