Note: 1977-1978 factory wiring diagrams for both XL and XLCH show a second wire from the battery (+) to a main circuit breaker.
The main breaker (74599-77), later changed to (74599-77A), did not come with wires.
And it is only shown in the parts books for 1978 XL, XLCH.
The wire on the FSM diagrams does not have a part number in the parts books nor is it mentioned in them.
