Default vacuum line

I'm putting the upper intake back in on my 86 and I can't remember where the very rear line goes to. There was a line coming from near the wiper cover motor, but it was slightly twisted so i'm not sure if that is the one. here's a diagram of how i think it should go (the red line). is it right? if not, where does the line coming from near the wiper motor go and where does the one from the plenum to the HVAC go?

thanks.

ps this diagram was posted by scorp, not sure if it's from a manual. but thanks for posting it anyways.

There are 2 ports on rear of plenum
One feeds air diverter and fuel reg and the other one is for the line you speak of.
:cheers:
