I am finally putting this thing back together after a year.
My question is on the back side of the plenum I have 2 holes shown below. I figure that one is for the brake booster vac but what's the other one for on the right side in this pic?
I think the third port is intended for the MAP sensor on SD cars.
I Just checked mine.
The third port as shown in your pics is plugged with a simple hex socket (allen head) pipe plug. There is a smaller hole between the other 2 vacuum ports which is also plugged with a 6 mm bolt. I believe the 6mm hole is also for the MAP sensor (maybe the mounting hole).

I just check my SR. I have a brass fitting on the drivers side and a vacuum line that goes to the brake booster. The other side on my SR is blocked off.
