Throttle Position Switches

[Cody Forbes]

The original post got clipped out and I don't recall the vehicle in question, but I had ETKA open when I read this so I took a guess. 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.
