On my 116.120, I have (3) lines at the plastic shift modulation valve (vacuum) on top the injektion pump. I marked everything when I removed the engine, but some of the tape has fallen off since then.

I have noticed there is one black line that somes off a 'Y' fitting, directly from the vacuum pump itself, (1) black line that goes into the car at the firewall and lastly, a single black line going to the transmission modulator.

How are these supposed to be routed??? Any information would be helpful. I just can't remember where they went.

If I hook them up 'logically,' the engine will not shut off. When I hook them up so the engine will shut off, shift quality is too soft to suit my tastes.

Anyone have a 116.120 / 617.950 they could take a look at for me???

I may be dealing with a vacuum leak, but I would like to make sure I have the routing correct before proceeding further.

Thanks very much...Bert
