So I am swapping a 1990 m20b25 into my '84 325e but you probably already know that.
Anyway the engine did not come with the vacuum lines from the booster to the throttle body so I went onto bmwfans.info looked at the parts diagram and picked up this from a wrecker.

However now that I look at my intake boot I have no place for that little plastic Y to connect.

As well there is only one connector on the side of my throttle body.

So this brings me to the conclusion that the vacuum system on a 1990 (my engine) and a 1989 (wrecker parts) are different.
So what do I need to make this work, part numbers and any other help would be hugely appreciated.
