Instrument cluster lights, '65 Valiant

For the instrument lights, the path is mainsplice to fuse box. Fuse to headlight switch. (Same fuse as parking and tail lights.)
In the headlight switch is the rheostat to control brightness.
Then it goes from the headlight switch to the fuse on the far end. Its a 2 or 3 amp fuse.
Then finally to the back of the instrument cluster.

On the headlight switch B1 is power only for headlights. There's an internal circuit breaker.
B2 is power for everything else in the headlight switch and is fused.

This is the 1965 power scheme.
