Anyone recognize this part?

[harwood1994]

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!

I sure don't recognize that thing.  Sorry.

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

Certainly not Ford.

That it was wired to the A/C doesn't mean it has anything to do with A/C.  I'd look for any ID molded into the case, and crack it open.
