Throttle Position Switches

[Cody Forbes]

I looked it up in ETKA for a non-q 4000. I would bet it's the same across pretty much all CIS-E non-turbo 5cyl engines and probably some 4cyls too. I can confirm tomorrow, or more quickly Huw can confirm since he knows (or forgot!) pretty much everything there is to know about the non-turbo engines of that era. I'm a turbo guy and know virtually nothing about the non-turbo engines ;-).

It says it is for the 80 or 90, and the diagram displays a diagram of the steering column.  But it might be available.  So, your manual lists that part # as being applicable to the 4000 Quattro?

Part number for an '87 4000 throttle switch assembly (both switches with wiring harness) is 026133093D and it looks like several internet vendors at least list it as existing.
