It t was then that he realized that the condenser also needs airflow and not just the radiator.....doh

So to add to the diagram: pin 87 of the pcm relay and pin 87 of the trinary switch relay will both be hooked to the hot wire on the fan?

In the interest of pursuing alternatives: could I not just wire my a/c signal on wire (clutch hot wire) to pin 86 of the additional fan relay and forgo a trinary. I believe this would turn the fans on any time the clutch was on.

Since the PCM gets a A/C power signal and controls the clutch....could the fans not be programmed to turn on with the clutch with no additional mods?

Thanks for all the advise and patience. I'm just trying to fully understand my options.
