67 Dart Headlight Switch and Connector Recommendations?

D had continuity to the pad behind B2 when the rheostat was fully counter clockwise but nothing else.
I assume it does something but not sure what.

Dome light.
Its one of the return side wires from the dome lamp.
Closing it will complete the path to ground.

Did some electrical testing, no more than 0.4 ohms on any contact.

I can check my car's switch next I'm at the garage.
.4 Ohms seems kindof high to me. Check the meter first. Could be 0.1 - .2 ohms just touching the probes together.
B1 to H will see about 9.5 amps IIRC. That would be a 3.8 Volt drop and 36 Watts of power in the switch!
