THANK YOU for this diagram ! .
If you remove the passenger front footwell carpet and gently unlatch and raise up the black plastic cover you'll see #22 is TWO three way vacuum rubber connectors ~ this is the ideal place to connect the vacuum source to unlock the trunk .
FWIW, the large vacuum resivoir has a completely
separate solid yellow pipe leading directly to it from under the hood on the firewall ~ it doesn't take a long time with a manual 'Mity-Vac' tool to begin filling it, you'll notice the vacuum gauge beginning to rise off the peg slightly after 6 ~ 9 pumps .
This is do - ale @ home much more easily and cheaper than you think so don't give up yet .
Please post a photograph of the trunk's lock cylinder A.S.A.P., there's important info there .
I was recently told that all W123 Coupes have the emergency release wire but they don't, I have looked *very* closely having owned four CD's .

You also need something that if there is a leak in the system will evacuate the system fast enough to still have enough vacuum to operate the trunk lock. Also why it is better to tap into directly into the Trunk Lock Vacuum Line.
See the diagram. Both the Diesel and the Gassers have the #6 Vacuum Resirvoir for the locking system.
