they are the switches for the upshift light controller...
I posted before about having this random switch in the engine bay and it turns out that it's supposed to be attached to a bracket like in this picture (front of the pump holding the throttle cable):
What bracket is this? What engines/cars did they come on? The bracket on my 82 looks different and doesn't have a place for the switch. I'm trying to un-ghetto the car as much as possible and this is one of the last things left.
And this is the switch that's just hanging out in the bay that's otherwise supposed to be on that bracket.
all i can tell you is one came on my 85 turbo diesel jetta.
and the bracket is actually 2 pieces. the main part on the right which has a couple holes so that the smaller l bracket on the left can slide in and pin itself in one, then be bolted to the pump and stay put in the other.
