I have a '66 Grand Prix with the vacuum trunk release. It also has ATC A/C. This might affect things???

My car has TWO Vacuum tank canisters. One larger unit is located on the top of the left hand side (Your drivers side), inner fender. This unit appears to be associated with the ATC A/C.

There is another, smaller tank located up above the glove box under the dash top. From memory, it is about the same size as yours seem to be.

HOWEVER, I need to stress that I have never really followed through how all the vacuum lines are interconnected. I have vague memories from when I have been under there that the smaller tank is connected via a "T" piece into main vacuum line feeding the ATC controls. That might be a bit wrong so please don't take that as gospel.

It would make sense that this one is for the trunk release - I assume the pushbutton goes inside the glove box? That's where it was in my old '71 Catalina.

Yes Stuart, the push button is inside the glove box, closest to the driver and just under the hole for the light.

The vacuum tank (on my car) is directly above it. I only have ONE vacuum tank under the hood.

Yes that is correct, the button is in the glove box. I guess over the glove box is where it will go! Thanks for the help.
