Need some Vacuum line routing help.

Hello all,

I just replaced my heater control valve (although Im not sure that it is going to fix the problem) and I am not sure where two of the lines go. One I thought goes to the heater control valve and is a black line with a 90deg bend connector on the end and comes from the right side of the engine (circled in green in my picture). The other line is a blue line with a straight connector that is coming from behind and underneath the rear of the fuel rail/cam cover etc.

Where do these lines go? I have a feeling the blue line is the one that is supposed to go to the heater control valve but where does the one from the right come from?

Im trying to use this diagram that I just found to help me. Looks like the black line is from 'control valve II'. Also a check valve was loose that I put onto a larger vacuum manifold that runs along the top of the firewall.

Ok, I think that i figured it out, the blue hose is supposed to go to the heater, the black goes to a port on top of the engine.
