1983 300SD.

The vacuum hoses on this car were all mixed up and no vacuum was getting to the modulator. Shifts were very hard.

per shop manual diagrams and engine sticker I've hooked up the hoses correctly. I've also tested each component and adjusted the linkage per spec. problem now is that vacuum always remains at the modulator (22" Hg) even when the switchover valves are rotated (should go down to close to 0 at full throttle). I have the three vacuum pipes (EGR, source and vent) going to the switchover connector (#1, 2 and 3) per factory but I can not find a diagram that shows routing of the little rubber hoses on the switchover valve itself. Can someone show/tell me this info? Some were disconnected and i suspect some are not connected to the correct port.

Thanks
