How do you assemble the pro-chamber? More specifically, there was a 4 inch metal coupler that came with the system, where does this piece go? Can someone please help..Thank you all for your previous tips.
 
the side with 2 pieces goes under the drivers side. In the middle it connects with the studs and nuts.

the paper gasket is for the passenger side PC to manifold connection, but i would't use it.
