My 85' Westy has them.  They are located under the TB as described in a later
post.  Mine did not work because the contacts were melted by an incorrect wiring
harness splice job done by a local shop in Oregon.  I did not notice this until
Ken at the Volks Cafe in Santa Cruz CA pointed this out when he was diagnosing
an unrelated problem.  When I had them replaced I did not notice any change in
performance or engine sounds. But I feel better the switches were fixed -- who
know what symptoms down the road they might cause if they weren't working.

Subject: Throttle switches on 1.9 WBX

Volks,

At the PA Vanagon breakfast last weekend, I ended up staying around for lunch
(he bought...thanks) with one fellow from New York City who had driven down in
his '85 Westy.  We popped engine hatches to check stuff out here and there, of
course.

Anyway, this 1.9 didn't have throttle switches.  Now, I'm used to the buried
system under the throttle on the 2.1, but I'm pretty sure (and we confirmed in
Bentley) that the 1.9 has two switches (one for idle and one for WOT), but this
van had neither.  It seemed to purr just fine at idle and generally had a good
sound for a WBX with over 150K.

Anyone know if the 1.9 ever came without throttle switches?
