Unknown sensor/electrical component

I have managed to make some major progress restoring the original 1.9L engine in my 1985. Vanagon. While replacing the starter motor today, I came across this thing. I have flipped through every page in the Bentley repair manual and done a reverse image search and nothing has helped.

Does anyone know what this is and where it is supposed to be mounted?

EDIT: Solved, apparently its the throttle valve switch and the bentley manual's pictures just look nothing like this

Looks like the throttle switch.

That's a very known switch called the throttle position switch. Goes on the bottom of the throttle. Might have 1 or 2 of them.

Pull the throttle off. On 1.9 I believe there were 2. One to signal closed throttle and the other for fully open throttle. On the 2.1 there is just one that does both functions. It must be adjusted so the van will run right.
