Hi, I just purchased a 1968 911 S. It is a European model, and the dashboard knobs are not marked. I have found the lights and the lighter, but it has 3 more knobs next to the ashtray, the center one, I think is the windshield heater (this is the only one with a sticker on it). There is a two step pull knob on the right with a light that goes on afer the second pull, and the one on the left seems to do nothing.

The car has no fog lamps, and no warning (hazzard) lights (1968 Europeans didn't have one), so one of them must be the gas heater, any idea what the other does? The car has a rear defroster, though it might be aftermarket.

Thanks
