Rear Combo Light Wiring

Where does the power go into the light? I know it seems like it should be obvious, but I'm not seeing it.

The stud on the center rear of housing is the power contact. The wire to the switch power in goes to that screw hole. The switch (not shown) has connections for each of the lamp wires. It is a three position rotary switch (IIRC) with OFF red and white positions. Jim

The switch (not shown) isn't present either. Bummer. I'll be alright because I got the light for free! I'm thinking of putting it on the rear of my SMTA so I can actually see the plow when plowing at night.

I think I understand what happens once the power is inside, but how does it get there?

Edit - I think I get it! There are TWO screws. One on the outside and one on the inside. You use the fork or round loop connectors and the brass threaded thing sends the power inside.

The stud on the back is a pass through.
The switch is very common. I would search for a water resistant three position rotary switch. Digi-Key will have it. Jim
