Vacuum Plugs

[WEIRDGUYWITHAKNIFE]

I am at a loss to make much of the diagram. I have been left with the 3 plugs in the picture, I believe 2 go in the manifold and 1 in the plenum but am unsure. If anyone can help it would be great. thankyou

Yes the two on the right go on the underside of the upper intake. The bottom left goes on the left rear corner of the lower to run water to the backside of the throttle body spacer.
This pic should help with you vacuum fittings.
