Wiring Fog lights - 76 with backdated bumpers Options

I thought I'd better start a new thread on this rather than continue here...

Foglights on a 76 with backdated bumpers

I'm down to the wiring. It "appears" that everything is in place although my 76 never had factory fog lights. The wiring to the fog lights is in place and terminates in factory connectors behind the front panel. The three wires to the fog light switch are ready to hook up behind the dash. It looks like the fog light relay is there (last round relay on the fuse panel?) and I have power at the #10 fuse (red with black tracer) that I think powers the fog lights.

I installed the factory fog light switch and no go (no power to the fog light connectors behind the front panel.

What am I missing? Hopefully something simple like, key needs to be on, headlights need to be on? Or is there some of the wiring still missing?

Thanks.

This reminds me of the Volvo 850's, they had seat heating elements and wiring all in place. If you had a car without the factory seat heaters all you had to do was buy the switch, pop out the blank, install the switch and then you'd have heated seats.

Cheaper for a company to keep track of one wiring harness part number I assume, plus fewer differences on the production line and easily retrofittable at dealerships when new.
