Unfortunately one doesn't exist. The service manual has generic information but doesn't really show you what wire goes where.

Makes troubleshooting more of a trial and error affair.

Sorry,

Brad

No gutting needed. Tracking down a short is not easy. Yesterday Manouch told me what he was going to do to find the issue and he's going down the right path.

He'll get it figured out.....

There are two types of issues with these old buses.

1) They are over 40 years old and weren’t thoughtfully built in the first place

2) They have had 40 years of tinkering to work around 1)

Initially it can be a troubling combination!

If I recall correctly on my 77 24' the trailer wiring harness goes up the drivers side from the rear bumper along the frame for a short way. Mine had splices EVERYWHERE.
I dont remember where, but somewhere the trailer harness doubles back to meet up with the tail light harness.
