Need help with Tpi engine vacuum layout

Can anyone please give me some advice on where i should go for detailed images with labels pointing out where vacuum connectors, coolant lines, electrical connectors etc. where they go/belong and what they ultimately connect to... ive got an 87 tpi 5.0 engine on a T/A and am unable to find this information.. ive reconnected everything with the help of a labeling system but 1 or 2 connectors remain and im not sure exactly where to reattach them... perhaps if u could give me a link to photos of where everything goes.
Ive gone through all the manuals i could but none of them seem to have detailed information, they assume that u already know how everything is / how it goes.
It would really help me get my bird back together asap.

Re: Need help with Tpi engine vacuum layout

Well ive got a couple black hoses running from that thing in the right front corner of the hood ( im assuming it is part of the cruise control system as it seems to directly respond to changes in throttle position) and it splits into 2 lines in the middle of it, on the other side i have a similar hose that also seems to have no corresponding plugs but ill look at what youve sent me and try to go from there
----------
my email is
noqeustions@hotmail.com
are those hoses shown in teh diagram the only essential ones.. if i miss some of the others will the car still run / idle properly?
