92 d150 ac

Installing a aftermarket electric fan, the green wire needs to hook to the positive side on the compressor clutch switch. Would that be the blue wire or the black one?

You need a relay to hook up to a "trigger" wire which would be the compressor wire. You can't run the fan off just the compressor wire. It should be the 87 wire after the relay.

yes I have a relay just want the fan to run also when the ac is on. Its setup to turn on at 170 temp, but also has the wire to run to positive side of compressor that will turn on fan

I assume you are adding this fan it's not replacing the stock fan correct?
