I am restoring a 1982 westy that had the rear interior removed by the
prior owner.
The Bentley reads that the ground wire (large green wire)  from the
circuit breaker
grounds "on body, left side".
Maintaining a stock configuration is the goal.

Does any have guidance on where exactly it attaches? Photo would be
appreciated.
Also, anyone know what the black box is in the photo?
