My only concern is if it's needed for throttle input...

I often regulate the A/C engagement on the highway if I'm going up hill or downhill -- which still requires throttle input.

Perhaps it can be TPS-related (i.e. < 18% throttle = A/C engage). It would have to be a precise mechanical placement or hacking into the TPS output, determining the voltage, and running a relay of some sort. Maybe a potentiometer could be involved to adjust the setting instead of a fixed output trigger.

Note: I don't have much electronics experience, so this is pure brainstorming (implementation would require assistance from others

)

EDIT (follow-up question): Are the fans generally required if you're at highway speeds without a grille block? It would help to shut those down at cruise...
