I've done exactly what you are considering.  My '84 throttle body shaft was
badly worn, and I was able to get a good used throttle body from an '85
model.  The two switches on the old one are wired in parallel, so it wasn't
a problem to go to the single switch.  I was also lucky enough to get the
'85 wiring harness connector so just cut off the '84 connectors and spliced
in the new one.  It works just fine.

Subject: Throttle Body/Switches?

Volks,

Does anyone know if the old type throttle body with the two throttle
switches can be swapped for the new type with just one switch? Can I
just move the whole assembly (throttle body with switch attached from a
1985 to an older 1984 that has the dual switches) from the 1985 to the
1984?

Thanks
