On the late 2002.-07 gm vehicles with P59 PCM don't use an air pump but the output is still in the P59 PCM, the temperature is just turned up where output will not come on. My question is has anybody repurposed this output to use for something else? I'm thinking about using this output to control my cooling fan for my transmission cooler. Just want to know if anybody here has repurposed this output successfully?
