My mechanic is correcting a lot of jerry-rigged wiring jobs on my 1981 f250
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
Thank in advnace!

That is definitely not a Ford plug, and more than likely it's a dealer or aftermarket A/C system.
