While installing my new starter I somehow unplugged this thing. Car will start but will not run without this plugged in it seems.
I believe I’ve found one of the connections but I’m not sure.
It seems that the device is a vacuum line that is supposed to plug into the pictured thing. But the pictures thing is appear plugged into something else
🤨
The probed picture is from a 2001 boxster. I have verified that connection B is made but that connection from the earlier post (K) seems to be plugged into something close to (C) and that connection is set up with what looks like an OEM rubber housed connection.
Do I just unplug this thing and set it up as shown in the picture or what?
Under the throttlebody, behind the alternator, feel around for loose vacuum lines in there….. probably need a flashlight to poke around under the throttlebody. For reference, you can see the water pump pulley at the bottom of the pic….. looking from inside the car towards the engine…..
this pic is from the side of the engine, the item you are looking for should be below the hose coming out from between the intake runners.
….I already knew that. That’s what I was illustrating earlier.
That it was odd that my car doesn’t seem to have a connection between this part and the vacuum change over valve. And that the tube on the vacuum change over valve is connected to something way off to the side….

I have redone the vacuum lines on two engines and first thing I noticed is that they are not always connected the same way, which is not important in terms of operation but can be confusing. Looking at your diagram above.
- B and C are straight forward, visible on the front left of the engine
- parts E and J are control valves J is on the left of the engine between the intake tubes for cylinders 4 and 5, it's easy to see and is not far from C. The input line comes from the right side of the engine (I) and the output line goes to the valve K on the inlet manifold.
- L is the port in the intake manifold that supplies the vacuum to most of the system, it is on the right side of the engine on the forward manifold crossover tube, H is a one-way valve that is near the part L.
- F is the vacuum reservoir (which has had a crack in every one that I have seen and therefore leaks... but that's another story). It is located under the right side of the intake manifold just forward of the AOS, you can see it in Eric's photo, the grey dome.
- D and E are just foreword of the reservoir and therefore just behind the alternator. Logically this is the one that you have misplaced... but something length of the lines doesn't look right, but I may be wrong.
The final picture in your original post shows one of the three-way connectors, evidently missing one connection the other two likely go to the reservoir F and the valve E. so the missing connection should go to I.
Note!!! the lines in the above picture show the connections but they are not the lines are not the real lengths. The line between I and J is about a foot long because it goes from the right side of the engine to the left side.
First look on the left side to see it the valve is J is where it should be between the manifold tubes.
I will have a look at my engine tomorrow to be sure I have not lead you astray.
