What is the purpose of the light at the end of the red arrow?

Correction: Hot light for the California cars catalytic converter is the one between the instruments on the California cars that says "cat" The white circle on the fuel temp gauge on the 914-6 sportomatic is the hot light for the oil

It's a "ain't one" light. The bulb holder behind it is for the bulb that illuminates the gauge. I guess VDO put the dot there for symmetry?

It is a 1976 California car.

There is a "cat" light is between the tach and the speedo. There is an "EGR" light between the tach and combo gauge.

I bought the car without an engine and I have put a SBC in it. The computer is gone (of course). I guess it could have something to do with California smog laws but I can't think of what.

Anybody with a late Cali car?

Maybe the owner's manual has an explanation?

If the gauge is part # 91464110150, which you can't really see when it's in the dash (it's directly over the temp gauge on the inside lip) then believe me because I have one, in my hands about to go into one of my cars, it's not a warning light of any kind. It is a blank for the bulb that illuminates the Tank and Temp gauges when you turn on the dash lights. Not sure why the Dr. doesn't know this, maybe he doesn't have one in front of him.

Those two lights were hooked up to one or two systems which turned them on and off. The EGR light came on when a specific distance had been traveled. There was a special speedo cable that went from the output on the transmission to a gizmo in the passenger footwell foam. That gizmo counted up to some number, and turned the light on after some distance. There was a reset button on there to turn the light off. A short speedo cable ran from the gizmo to the speedometer.

The CAT light was either run off the same gizmo, or from a temperature probe in the exhaust. I believe there was a controller box of some kind in the rear trunk on the rear panel near the left taillight, and the light could be reset with a button on there?

Been a while since I have read the 75-76 owner's manual, though.



The Doc is correct, though--the "extra" light in the combo gauge is shown very clearly in the 914-6 owner's manual as the Sportomatic Over-temp Light. I've never gotten a good look at the instruments in a Sporto 914-6, but evidently that opaque panel was replaced by some gel like the other lights and had a warning light on it. Don't know where the mechanism that turned it on and off was, though.
