Rees, BCB is right. I have a 93 P2 that nothing worked and had all the lights in the boxes stripped out of it. It was a wiring nightmare. I had Richard to send me a wiring diagram along with all the pumps and auto bilge switch I ordered. I thought once I had the diagram in hand Id be good to go… WRONG. Its a real wiring schematic, which is what I ask for, but I was still lost. I called Richard and within 5 minutes, he told me the color codes and where they went, and it was pretty simple. Now, with his help, everything works (except the auto float bilge switch??), and Im good to go. Wiring is NOT my thing, but Richard was a ton of help. Give him a call.
