Default Vacuum Port by EGR Tube

Question. What plugs into the Vacuum Port in the rear of the Intake Manifold by the EGR tube connection on a 1990 Supra N/A? I don't see anything unplugged.

Thanx from 10EC.

A photo would help. There should be a vacuum diagram underneath the hood of the car. The only thing that sounds related is are you talking about the power steering booster hose? You can consult the online Supra manual. http://www.cygnusx1.net/Supra/Librar...3/default.aspx

OK, easy. That hose comes out and connects to a plastic T on the firewall. One side the T connects to a hard plastic hose that goes over to the heater control valve. I think there's a vacuum check valve there too. The other side connects to the cruise control and further on connects to the vacuum / pressure transducer that displays vacuum / pressure on the dashboard. There is another double T in that line between the cruise control and the transducer. See the photos and arrows. This is on a 1987 Turbo car. There may have been some changes between non-turbo and later years.
