I am looking for some help. No one seems to know anything these days.
I am changing out my clutch coil on my ac.
My old coil did not have a clip to connect to just wires sealed up with wire clamps,
The wires on the coil are black. I need to know how to figure out which side is the hot.

Any help would be appeached.

 

You can try here, for wiring diagrams. But, as it's just an electromagnet, not sure polarity even matters....

 

You can hook up the wires either way. A coil is just a wire.

 

I have posted all Tipm and ECM wiring on a 2009. I believe it covers 2011

 

Thanks.
Still not sure of that. reason being I have a blue/black wire which is positive and black neg. wire.
Your thoughts

 

The coil in the clutch needs power and ground. So far as I know, it simply doesn't care about polarity. Try it, see what happens.

 

I can't help but point out the irony of you saying that and yet you are here because you yourself don't know something lol.

 

Per the wiring diagram for the 2011, the clutch coil wires should not be the same color, and the wire that doesn't just connect directly to ground should have a connector in series. But if you're saying that the replacement coil has only two black wires and you're unsure how to splice them, then the answer remains "it's an electromagnet, DC polarity does not matter in this case." Just like a relay coil which will work with the polarity either way.

I should add that the above was for the Automatic climate control, and I got a bit lazy with my yellow box and see that I captured the location for the pressure transducer versus the location of the ground. If your truck has manual climate controls it does not change the wire colors or the ground location for the compressor clutch.
