Dan, I have noticed you have got some information that's not totally correct. First I would restore the wiring back to the original condition. If you need help you can call. The otterstat and AC control mode switch turns the fans on and off. The fans are turned on by temperature of the otterstat.92,97,98 Degree C.( I have 3 temps on the web site. ) The otterstat works simultaneous with the AC compressor clutch turning on and off if needed. ( Meaning they can both be turned on at the same time.) The protection of the circuit working correctly is as good as it's weakest link and The Fan Fix Dual 2x2 can fix it safely with less strain on the wiring harness of the car for other components. The Air Bleeder can continuous bleed off any air that gets into the system that would hinder the otterstat from doing it's job correctly. Your thermostat above the water pump needs to working correctly and the radiator should not be clogged up. With normal maintance the system should work fine in any weather.
