I have a set of aftermarket electric fans that draw alot of air and alot of amps. Currently, they are controlled from a stand-alone unit that turns on at about 185-190 degrees. I want to control the fans by the pcm.
What I need to know is how to wire them up so one turns on at a certain temp (lets say 185) and then the other turns on at a higher temp (lets say 200). How do I do this and what pins do I tap into on the PCM?
Thanks for the help!!
