is there any other ones for the rest of the pipes?

all the other small pipes come from the vacuum points on the throttle bodies. the only one not shown in diagram is the one from rear black box (vacuum chamber) which goes to top of carbon canister.
some of those pipes maybe re routed on your car though as the above diagram is on a bog standard car

yeah sorry should of said i know those ones. i ve got my inlet manifold off to check all of the pipes and hoses. i would like to know about the two black boxes one of them is bolted too the bottom of the manifold and one to the block they both go in to pipe work what are they for? and what flows throw them? also the pipes go in to the carbon canister from it if i remember correctly whats the correct order?

there should only be one black box on back of plenum which is a vacuum chamber box (a kind of junction box if you like for air)
the small vacuum pipe goes to carbon canister top
another goes to oe recirc valve
another goes to fpr which then tees to boost gauge sensor box iirc
the bigger pipe goes to larger intake on carbon canister
