Fuel pressure regulator goes to the small port on the far side of the intake plenum. The larger of the 2 ports goes to a 2 way check valve. From the side of the check valve goes and splits by the cruise control, going to the cruise and going to the vacuume ball in the frame. From the other part of the check valve, a vacuume line runs in though the firewall to your HVAC controls. (Or near it)The largest single port on the back of the plenum goes to your brake booster. The port on the base intake manifold goes to PVC. Egr silonoid connects to the egr valve and then to the port located under the Throttle body. The larger of the 2 ports on the side of the TB is a fresh air tube to the passenger valve cover and the lower port is for the charcoal canister. Thats it for vacuume lines.
