What's German for "two steps forward, one step back"?  "Vanagon", of course.

The aforementioned throttle valve switch, after all of my loving care, took
a complete crap on me.  The switch doesn't click on at all under any
condition, either by use or even manually.  It's dead, and I have no idea
why.

Someone, whose e-mail I have since deleted, stated that it's possible to
switch the plugs for some other component with the TVS plug and thereby kill
the TVS.  At the time I didn't think I could make that mistake, thinking
that I had positively identified the right plug, but now I'm not so sure.
Yet I even checked the Bentley's and I didn't see any possible suspects from
the wiring harness that I could have switched by accident.

Anybody else have any experience with this thing?  In the mean time:
"Yoohoo, Bus Depot..."
