Vintage Optilux Fog lights - Internal Wiring ?

[ruby911]

I just picked up a nice set of Optilux lights that I will be using as TTG lights on my '68. Electrical subjects is one area I know zero about, so I am hoping someone can help me with how the wiring is supposed to go inside these things. Inside the lights, there is one wire that is connected to the housing that I assume will connect to the male end on the back of the reflector to serve as a ground (please let me know if my assumption here is wrong).

My questions are...
1) How do I ground these?
2) How do I connect the bulbs (H3s)?

Pics below to show what I am working with.

Thanks for help provided, Farrell

Yes, you should connect the ground of the bulb to the spade clip on the back of the housing.

However, this will not give you a good ground through your mounting plate/bracket and fender well unless you take off some paint/undercoating.

I think you would do better to run individual leads to the bulb through the rubber grommet.
