1966 Coronet

Factory AC is not working. Just discovered it is missing its harness to pressure switch. Any ideas where I can get one? Thanks, Clark

There is no pressure switch. Are talking about the clutch wire under the hood or the overlay harness under the dash?

I replace the receiver/drier on my 66 belvedere with an auto-zone drier and it came with a pressure switch on it(must be a universal fit). Guessing this is why you have a switch with no wires going to it
