85 300SD w/ Trap Oxidizer vacuum presure reading

I followed Kent's instructions the best I could in his Vacuum Diagnostic manual. Here is what I did and what readings I got: following the main black plastic line to the firewall, there are several lines that split off. 5 in total, I believe. I unplugged the four smaller, colored lines and plugged them with golf tees. The remaining line is actually some sort of plastic housing unit with a curved rubber hose attached. I took my measurements from this point and with the engine on, I got a measurement of 10 psi from my mityvac. I think this means something is up with my vacuum pump, unless I performed my measurements incorrectly.

Alarm Buzzer Steering Lock 1983 300SD

Kent,

I have read your manual for the replacement of the steering lock + tumbler and purchased all the parts I need. I have a steering lock from a very well maintained 91 420SEL. Can I use the alarm buzzer from that one for the steering lock of the 83 300SD? It is different in that it allows for one more plug than the one on the 300SD - but the other plug looks the same.

Thank you
Dieter

1984 3ooTD Tailgate will not unlatch

Help! The tailgate on my 1984 300 TD will not unlatch. It won't open from the inside or the outside. Lock button pushes in... nothing. Lift the inside lever up... nothing. Unfortunately, I'm not sure it's actually "unlocked" as that whole emchanism feels wrong when trying to unlock with key. Is there a way to bypass everything and at least get it to open so it can be worked on?

1985 300TD - How to Repair Damaged Vacuum Hard Line?

I had a short which burnt through a vacuum hard line under the dash. After that the car wouldn't turn off. I cut out the small burnt section and reconnected the lines with a short piece of 1/8" rubber tubing. The fit seemed pretty snug but still the car only turns off after a few seconds. How can I make a good repair to the hard line? Should I be gluing the rubber tubing onto the line? The hard line is behind the steering column and very hard to access, so the simpler the better.
