Cool... by the way, if they aren't "hooked up" mechanically, there is no 
need to plug in the throttle body switches.  Though I suppose it does 
help keep track of the connector.

I guess that would work, though it sounds like a messy place for 
switches and wires.

I suppose the body of the unit is probably the other terminal.  Which 
might be a problem if the Audi control unit does not want to see ground 
on either side.

Surely you can rig up something, a bracket or plate, to hold both 
switches in such a fashion that they work again?  That all the fun of 
these engine swaps, right?  Building non-existent parts that you need...
