Any one recognize this part?
It had two owners before me
He said the wiring went from the harness, to a relay and from the relay to this light blue guy
We are pretty sure that the wiring goes from this to the a/c compressor but he has no idea what this is and it isn’t showing up on the Haynes manual
We are thinking that this truck had after market a/c installed somewhere along the way. The compressor itself is fried at this point and looks old but the wiring job and the lines definitely aren’t factory
thanks!
