So i bought an RBC from a guy on clubrsx. problem is......

There are 2 ports, extra vacuum for the boosted folks

Well im not boosted and im trying to find the two ports. I found the one right on the top, what are the locations in which u plug the ports?

the other port is right near the throttle body. it's the location of the map sensor on an rbc manifold. research.
