I ask this question because I got my electrical connection backwards on my 80 wagon, and it melted the wiring harness all the way to behind the instrument cluster.
Coming out of the AC compressor are two spade terminals, where the electrical connection goes (duh so far). My old compressor had an X over the passenger side spade. My new compressor has an X over the drivers side spade. Is the X for the positive lead? And that is the blue wire right, as the brown should be ground.
Simple question eh?
