Well ,here is the new plan. I just got a throttle body from an 83.5,or 84.
It has 2 throttle switches and is low mileage(82K).My 85 has 1 combination
switch,currently,to do the switching chores.. However,both throttle bodys
have wiring harnesses from the ECU that contain only 2 wires. The throttle
body that has the 2 switches ,has the harness branch off into 2 extra wire
ends.The Bentley shows this to look the same in each schematic(84 and 85).
I can splice this into the current wiring and solve the problem, right? The
reasons I am doing this is costs($25- once again,still more than I wanted
to spend).I can adjust this ez, where as the late switch may need the TB
removed to adjust.I can get replacement switches from other junked VW cars
to fit this TB. The wiring from the future replacement switchs will need
push on plugs added(no problem),if I cannot find a doner vanagon made from
83.5 to early 85(shouldnt be hard to find).The early WBX throttle body has
no adjustment screw on the throttle stop. Only an adjustment screw for the
decell switch.Anybody know if this TB swap will cause a problem  in the
preformance of the engine?Cant see why It should,but then again, shouldnt
have to do this anyway.Thanks
