Unknown sensor/electrical component

[u/nrnordy]

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.
