just changed my turbo.... but few questions... help appreciated...

well as you know, ive been looking turbo for my car for a while, one finially popped up at local scrapyard for 150 so i took it... fitted it, but few questions.... ive left one vacumm pipe off and wondering where it goes as ive forgotten.

its located here: (excuse dirt of engine, needs cleaned)



the red box ive drawn, at rear of engine.....

this is the part that thee pipe runs off:



its the middle of the 3 pipes, i cant remember were it goes... somebody help...

also i think the plastic pipe that goes from air filter to centre of turbo may be loose... and its causing like a squeel off the turbo when it goes on boost. i needa get it tightened. as im scared to even go on boost at the minute. any help appreciated.

thanks
