I just swapped out my 1.8L for a 1.7L (so I could rebuild the 1.8L), and I can't find the wire that goes to the pressure switch.
I've got carbs, so the wire harnesses have a zillion unused wires. But I thought there would be a wire with a dangling connector somewhere nearby... apparently not. The car is a '74. From the wiring diagram, it looks like the wire should be green with red stripes, but I can't find that either. Can anybody tell me how I might go about finding the correct wire to hook up? Maybe the physical location of the wire run to start? Or where it comes from, or what other wires it would be with? Any help is appreciated, thank you! |

Gents, my notes indicate the OP switch wire is green/red and comes from the T12-1 pin on the relay plate (mine's a '74.)
If you were standing over the relay plate from the rear, the T12 plug is the 12-pin connector on the lower right, and the -1 pin is its upper left pin. Edit, actually a picture is worth a thousand of something... Attached thumbnail(s)
