Fairies will fly out of the tail pipe :mrgreen:

I honestly don't know but was too scared to eliminate too much stuff. I remember one went to the TB but can't remember where the other went.

IIRC the only purpose of that switch (valve) is so you don't have EGR function when the engine is COLD. You should be able to check your under hood vacuum hose diagram and verify that. Dennis
