couple of bits on a 328

[sutton01]

i have recently put a p reg 1996 engine in my 1994 l reg e36. i am now stuck on a couple of issues.
1. im not too sure how the heating is all connected up under the bonnet. if anyone knows anything bout that would be helpful.
2. there is a little breather pipe just behind the throttle bbottle on the bottom of the inlet manifold and i dont kno where it goes to.
3. i cant seem to connect up my throttle cable from the old throttle body on to the new one.
i would really appreiciate someones help if they could.
