Hello folks,
I'm wanting to add a fan to my intercooler on my car, but I don't want it to be on constantly.

Ideally, it would be somehow wired into the IAT (Intake Air Temperature) sensor and only come on when temps go above a certain point like 95 degrees. Then there would be an override switch inside the car that would normally be on that I could turn the fan off at my discretion.

The problem is that I am not sure how to do the IATemperature-dependent switching. I'm assuming it is a 0-5V sensor and temps correspond to voltages, though I don't know what that correlation is. Any ideas? Thanks in advance!

 

do you have access to a scan tool to map your new temp requirements against the exsisting voltage /temp map?

 

Yes, I could nick the IAT wire and get the voltage reading while seeing what my SCT OBD scanner says for temperature at the same time... get a few readings at different temps/voltages and map out a correlation
