I had someone replace the blower motor in my SHO, but the guy didn't take pictures of the vacuum lines before disassembly. Now, I have two black vacuum lines that aren't plugged into anything and my blend door isn't working.

The first black vacuum line comes from the driver side firewall and goes toward the A/C control unit but isnt quite long enough to make it there. The second black line comes off of a little triangular plastic coupler behind the glovebox. It has a white vacuum line beside it. The black and white lines originate at the A/C control unit and plug into the triangular plastic coupler/block. It's the white and black line coming off the other side of the coupler that aren't both attached. Only the white one is attached to the metal canister above the blower motor box. I don't know where the black one is supposed to plug in.

1. So does anyone know where the tiny black vacuum line coming from the firewall on the drivers side is supposed to plug in? (Pics by chance?)

2. And does anyone know where the tiny black vacuum hose behind the glovebox plugs in?

Thanks.
