RM 100

On my 79 MH the black wire is the 12V +, the white wire is -.
The black wire goes straight to the 12 V distribution panel and has its own 20 amp fuse.
The + goes on down to the slector switch, which has to be pushed in and turned clockwise to 12V (and elec).
This activates the small solenoid switch via the blue wire allowing 12V to flow to 12V heater element.
These old 3-way RM-100's are fine old refers and are well worth using until they blow.
