Does anyone have a picture of where the vacuum tube from the heater VSV goes. (SC300 92'). I disconnected the tube and connected it to one of the throttle body vac sources and the valve worked like a champ. So...the vacuum bracket that I have it currently connected to is either wrong or not strong enough.

The vacuum diagram on the hood doesn't show anything related to the heater valve.

i'll try and get you a decent pic on my lunch, I wonder if thats my problem though , cause you have to give my car a few min and finally the vsv will start working.

 

Old NA pic, just ran a T off of the line coming up from the vacuum tank over to the heater VSV.

 

I appreciate the quick picture. That helps me. Looks like you deleted the EGR in that picture or the EGR vacuum perch is gone. Anyway, I'm doing about 8 different things to my car right now and I'm just trying to get the little stuff working. I'll run it off that T from the vac tank.

Yeah, EGR is gone. When I initially did the EGR and charcoal canister my heater wasn't working and I didn't know why, until a friend pointed out the VSV with no line on it. So I put in a T and ran one over, and it's worked wonderfully since.
