1940 light switch

[rlh5window]

I pulled the wires off of the light switch on my standard 1940 coupe without a photo and do not know what wire goes to what switch terminal.

My switch has 5 terminals labelled P, B, H, R and another B.

I have four wires in the harness to attach to the 5 terminals.: black/yellow, yellow/red, yellow/black and tied together is a black and a black/blue.

The switch as two positions.

Any help? Photo?

Thanks, Randall
