yellow wire in right rear light assembly.

[robertel]

In my right rear light assembly there is a yellow wire which I cant match up to anything. Does anyone know what this wire is for?

Been told the right rear light is wired for rearview camera. Maybe that is what you have.

No cameras on a 75. I don't have anything like that on mine. It might be a rewire by a PO. You should only have brown (turn & stop) green (running) and black (reverse).

Yellow was used for back up lights by Airstream for trailers made to sell in Canada according to my Service Manual. You might check that lead.

It's easy to test all the wires by only powering one wire at a time. I've replaced and repaired anything on my 12 volt system so far with a multi-meter, a small battery charger, a jumper light, and a 7-way tester for the towing connection. I'd go to the 7-way and power one wire at a time and see what it takes to make that yellow wire hot.

I don't know whether your coach pre-dates the fiber-optic tailight monitor, but the thought that ran through my mind was - - could it be a fiber optic cable for the optional tail light monitor??

Good luck with your investigation!

Good catch! My '76 has the fiber-optic feature. I can't remember the color of the cable though. I bet that's it.
