I would like to have a functioning brake failure warning light operational
on my coach.
I have a 1978 Royale by Coachman. The wire that went to the combination
valve has been cut off somewhere by the PO. Can any one send me a link of a
picture that shows where the wire comes out from, the wiring along the fame,
or firewall, where ever so I can try and find where it is cut off so I can
reconnect it. If no one has a picture could someone please tell me where to
look. I'm hoping the cut off old wire is in a loom not too far from the
valve and I can just hook it up again.
Any help would be much appreciated.

Gary,
The lead to the combination valve switch should be a 16g Tan wire in the
loom along the left side of the engine hatch opening. The connector is sort
of a weird affair which is available from Jim K. As usual for GM
connectors, the price will shock you, but there's no compatible alternative
that I know of.
The next question is, "After you connect it, how will you know you have a
functional warning light?"
The answer probably is to simulate a brake failure by opening a brake bleed
valve and see if the warning light comes on when you press the brake pedal
firmly. DON'T let up on the brake pedal until you close the bleeder or
you'll introduce air into the brakes and have to bleed them.
