300CD vacuum routing for door locks

I've found some posts on the vacuum lines on the 300D's, and they say the main bundle of lines are under a panel in the drivers foot well. I found them in the passengers foot well. What I can't find, is the "T" or "Y" or what ever you want to call it, that connects the drivers door tubing to the other side. Anybody know where those connectors are?

Just using a little logic, I can see that the"yellow/green" and the "yellow/red" could make it from the drivers door to the other side without a "T" or "Y", but the "yellow" (main vacuum from the pump) would have to have a connector somewhere.

Oh darn, in re-reading this before I send it off, I'm actually using my brain and it's starting to hurt!....I remember now that there were two lines in the engine compartment, they both connect to a check vavle. One is "yellow" the other is "yellow/black", I'll bet one goes to the main valve at the drivers door, and the other goes to the vacuum tank. I don't remember seeing a "black stripe" on one, but I'll bet there was. If thats the case, the system is really pretty simple. Any one know for sure?

Solid yellow goes to the driver's door. Yellow with stripe goes to the tank. The junction you're looking for is in the driver's floor just in front of the seat. It lies in a channel covered by a plastic piece.

I'm thinking the coupe must be different, there is a plastic channel that parallels the door sill, only thing in there is wires (on the drivers side). In fact, the only plastic tubing under the mats, is a skinny blue one that goes to the seat back locks. I'm guessing that the sedans have it on one side and the coupes on the other, for what ever reason.......thanks Rick
