Center Console

What year is that??

This is a 71 Series II, Automatic with a Series I console (original) and a Throttle Control (Not original, nor OEM with an Automatic)

The red switch is the current switch for the fog lamps, however, thanks to Kats and Alan, I was able to get the proper switch for that panel, which is a Parking Lamp Switch. That switch operates additional bulbs in the front and rear but only on ONE side at a time (not blinking). This is to highlight your vehicle when parked on an unlit road.

What's the throttle lever for?

The throttle is a poor man's cruise control and tester / hey if you want throttle without your foot kinda thing

Actually it isn't, and that's the main reason they were removed when the cars arrived here in the U.S..

The Throttle Control does not have an automatic disconnect and as such is a DANGEROUS cruise control.

What it is for is for those times when you need the RPM to warm the engine up and not extra rich idle setting which is what the choke does.
