I'm trying to trace out the wiring in/behind the refer cabinet, I have figured out most of it but still have a couple loose ends.

There are 4 wires that appear to go to the switch panel just inside the door, mine doesn't have a switch there just a hole and 4 wires.

The wires are as follows:
Black, I traced to circuit #2 at the house fuse panel.
Grey, Switch lead to the porch light.
Yellow, Switch lead to the floor lights.
Green, unknown, was there a third switch at this location?

I also found 2 wires coming out of the foam just above the door striker (1 red 1 black).

The red one is ground and the black is unknown, they seem to disappear down the wall into the bath area.

Any ideas on these unknown wires?

Thanks

Have you downloaded and looked at the wiring diagrams?

Yep I have them, Colors listed on the wiring diagram and my coach don't all match and the part of the wiring diagram that shows the location of the component in the coach is not there, not sure there ever was one. and in my case I just have wires hanging out of the wall and no clue what they are for. Very Happy

From what I can tell I should have the porch light, and floor light switches on the left as you come in the door and maybe another switch but I just don't know. I have a bundle of wires and no switches.

Not being able at the moment to look to confirm, but just from CRS memory, I think my 76 PB had floor lights, galley light, porch light, and water pump.

The green wire (Schematic says it's yellow) is the galley light, Thank you Jay.

Still have the one coming out at the door to find, it looks like it was a switch as well, all of the wires going to the switches were spliced onto and all of them are red Laughing.

bpimm,
I have the same 4 wires feeding 3 switches. One each for outside light, floor light and overhead light. Best I can tell the overhead light was never installed. The wire disappears into the foam above the cabinet. Others may be able to tell you where to look for it. Can't help you with the black and white.

Thanks Glenn, I think it may be time to get a signal tracer to find the rest.

Mine also work porch, floor , water pump and overhead light. the overhead one is one at sink, that depending on the switch on the light fixture, i can eiter turn it on/off at door , or at fixture.
When it come to following wiring diagrams, At least for my coach, it may be a 75 model year on title, but it was built in 74, and sometimes info for 74 model year fits mine better
