According to that schematic, I can't seem to figure out where to wire up the
A/C switch and the temp switch so the fan will turn on low when the A/C is
turned on but the temp switch is not.

I sent you the actual schematic for the dual 50amp relay system. Just
substitute a simple coolant temp switch for the PCM (high) and the A/C
switch for the low speed fan circuit. Works really well and no issues at
all.

Sooooo, I'll be a guinea pig here... anybody care to rough me in a set of
plans incorporating 2-50 amp relays in the pdc instead of the malletized
version [sorry bud, I had to...]? I remember back in the day there was
someone that was doing up super cool wiring schematics for a viper fan
install....
