what kind of relay?

im trying to find a relay that has 2 12v input sources to turn it on...
what im trying to do is set up a relay to run my cooling fans and i need one that will turn on when the a/c comes on and i also have a temp probe that would turn it on when the engine gets over 180*
anyone know what relay i should use?

IT may be easier to make it like the stock setup and have on relay, and just make the temp switch and the AC switch supply a ground path. That way you can hook up both ground wires to a single relay terminal.

you could just use two relays. one for the temp switch and one for the a/c or you can put both inputs together and diode isolate them so that they don;t feed back into eachother. I'd say stick with the two relays and then you can wire in a bypass switch into one of them to turn the fan on whenever you want.
