s1cabriolet

hi, i'm still converting my mk3 cab with an s2 turbo engine, i have all the engine in but am stuck with a few little bits
i've read some posts but am still baffled and would appreciate simple (coz i am) answers as i'm not entirely sure what i'm doing lol.

please correct me if i'm wrong

top left inlet nipple goes to dump valve

top right inlet nipple goes to ecu plus boost gauge when i get one

the main water hose goes to water pump/matrix/oil cooler

the top left rocker cover breather bottom small hose goes to ????

the amal valve goes to turbo/actuator/metering head, but mine only has two outlets not 3 ????

i have to metering head connected to injectors, there are three other pipes, one goes to a round thing but where then? theres two more at the back facing the wheel arch, where do these goes, i know one goes to fuel filter but i'm really not sure ????

where is the turbo water outlet to rad, i can't find it ????

and the top hose from the header top just below the cap ????
any help would be great as summers coming
