Johnny, are you running the fan on high only? Was low speed not enough?
I grabbed the 12V+ from between the low pressure switch and the clutch so it'll cycle when the compressor does. Worked perfect. I ran the fan on low speed only and setup the temps for turn on the same way my Tbird's PCM had it setup. I was going to setup an emergency overtemp curcuit using a fixed thermal switch and a high-amp relay for the high-speed and have it come on at approx 230 degrees.
