Monkey of a mechanic messed up my K-Jet

Ok m8 of mine a former VW dealer mechanic offered to give me a hand rebuilding my mk1 cabriolet engine. To cut a long story short on reassemble he confessed he had never worked on a K-jet and had no idea where the pipes which were all knackered on removal go. I have managed to source some new/old pipes and fit them according to pics off google but still have some to sort…

1.There is a pipe outlet in the block where does that go?

2.on the back left hand side of the bulk head there is what i beleive an idle control with 2 tubes where do they go?

Pics to follow

oh yeah its a 1800 gti cabrio

No idea about q1 but q2 is the auxiliary valve. On the left hand side of the auxiliary valve (viewed from the front of the car) the rubber pipe goes into a steel tube that goes over the cold start injector. The other pipe on the right hand side goes into another steel tube that goes into the rubber which attaches to the throttle body. You really need to post some pictures here if you need help.

What does that go to?
