86 mercedes 30E, vacuum locks?

Sorry buddy. US and Euro cars differ alot. And UK cars differ even more than other Euro cars. Just because they make it in Germany doesnt mean they dont make different options. On certain older Mercedes like the 300E and 190E, UK models had different options like no power door locks, no power windows, right hand side steering like usual, and even the interior was different. Euro car engines are also setup different than US ones. But thats another topic, and my whole point in my first post was that maybe the UK member on the forum thought you had a UK model Mercedes.

if u have followed the diagram on page 1 and you have hooked up your alarm wire to the unlock relay that means you are puting positive + to both pin 85 and 86 put a neg - to one of these pins and then you can use the alarm output for the other. or on the alarm unit u can change the polarity of the central lock outputs but the easy way is do what i have told you first.

hope it works.
