I need help with 80 3.0 vacuum connections
I am installing a 80 3.0 into my 77 911 (2.7) , and I need some help connecting the vacuum lines to the back of the throttle body. There is a large sized hole at the top of the unit and a fitting below that . What two hoses connects here. I have looked at my 2.7 and they are not the same. Please see picture below.
Also, my rebuild kit came with two different sized studs for the intake and the exhaust ports. I need to know which goes on the intake and which is used for the exhaust . One is shorter than the other. The part number for the short is 999-062-006-02 The part number for the long is 999-062-008-02  Thanks Rick 77 911 3.0 |

I might be wrong but that looks like the connection point for the cruise control vacuum line. After I rebuilt my motor and reinstalled it I couldn't find the vacuum line connection point for the cruise control. I asked for help on rennlist and here but never received a good answer. When I pulled the engine for the restoration I found the unconnected port on the back of the throttle body. As I said earlier it look like the same one to me. So if you don't have cruise control I would just plug it and not worry about it.

P.S. it looks like you need to push the metal clip on that electrical connection all the way on. You don't want that coming off from vibration.

All of the vacuum diagrams I have seen never show the cruise control connection. The wiring diagrams for the cruise control don't show the vacuum line either
