This group of wires is going to nowhere under the dash, any clues? A missing relay? Thanks.
Can you identify where these wires go?

Wiring for aux foglights
can you follow where the wire comes from? the wiring diagram shows a gray / red wire coming from fuse 2 that is for the automatic selector lever. my coupe has the same thing ... but mine was originally an automatic. the wiring diagram also shows a gray / red + gray / violet as well as a brown going to the rear foglight. my guess is that's what its for
Seatbelt/ignition buzzer?
my ignition buzzer is still attached, and those wires are there on my coupe. i think rear fog is the answer as the wires are right next to the fuse box door ... which is right next to where the fog light switch would be
definately gray wires are lights
that's correct Alan, but the automatic selector has lights in them and it is powered with gray / red wires ... and on the 2800cs / early 3.0cs they were on the steering column - right next to the fuse door ... but so was the rear fog relay switch. Steve, tell us the color of the stripe on the other gray wire that will clue us in.

Sure looks close, I will get under there tonight and see if one of the light switches is missing its wires. No fog lights on this car though.
I've got my dash open so and have factory rear fog and a green button. Will look tomorrow.

No but the wiring is factory installed.
Rear fog light from my car.
yep - gray w/red, gray with violet + brown = rear fog light. Steve, i see the gray w/ red ... is the other also gray with red or is it gray w/ violet?

Were there separate factory switches for front and rear fogs or a two position switch?

there was only a factory switch for the rear fog lite - its green (like the amber rear window defroster switch).
I think those are the wires that connect to the "rear-shock-mounting-about-to-go" warning light!

case closed. i will figure out how to use some of these wires to power my fog light switch for the front fogs ... because i plan to use the green switch at that location. i just won't use the gray / violet as it goes to the rear of the car. the gray / red wires go to fuse 2 and the other side of it goes to the headlight switch (contact 58a) ... which provides power for the dim circuit to the gauge cluster.
Cool, thanks RS et al.
Gray-purple is the rear fog light and gray-red is the supply voltage (from the headlight switch) for the rear fog lamp switch, which connects both of them thus lighting up the rear fog light. My euro '73 has two separate switches for front and rear fog lights, as the schematic diagram indicates it should. That gray-red also supplies license plate lights and other minor lights. Again, this is all for '73 and later, earlier schematic only shows one switch for both rear and front fogs.
