Got a 1989 square body efi GMC jimmy. Going to be a project. Can anyone tell where the vacuum line goes that comes out of the fire wall from the interior climate control? The previous owner disconnected all lines. Is there a diagram? Thanks

Welcome aboard, feel free to fire up an introduction thread for everyone to say hi and a build thread for keeping track of your vehicle repairs and sharing with the rest of us.

Behind the throttle body in the intake manifold there should be a place to plug it into a threaded vacuum fitting. I will post a pic later if somebody doesn't beat me to it.
