Thanks I agree. Here is my plan. I already have two fans and two relays working off the PCM. Works great. So I am going to add a 3rd relay independent of the other 2 and find the wire that when the interior a/c is turned on to the trinary switch it will power the new relay and then off the relay I will go to the downstream end of both current relays and hook up there to power the fans
