86 mercedes 30E, vacuum locks?

ok i have a mercedes 30E 86'. Im installing an alarm with door locking and im just wondering how it will hook up to the vacume locks. Iv been on another UK forum just for Mercedes and one dude said you need a central locking module. But i havent had any luck finding one. I am kinda stumped on what to do. Its kinda tricky because i dont have a switch that locks/unlocks the doors, so it all vacuum. Anyone got some ideas on how to tackle this?

Follow diagram or add an actuator. Central locking module=keyless entry/alarm. Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

im still confised where am i supposed to hook the wire from the alarm up to it??

the alarm wires hook up on those relays on the left relay pin 86 and the right relay pin 85 these operate the relays for locking/unlocking but they have to provide a longer pulse to operate this type of system longer so you might have to program the time on the outputs of your alarm

I think that the vacuum runs under the back seat on the passenger side. I could be wrong, but I saw an installer in a Benz messing around in the backseat and saw the car doors lock after he did something with the wires.

im not sure where the pump is i have never done an alarm on a mercedes before im sure someone here will be able to tell you.

ya it is in the back, under the seat im 100% sure. the only problem is the get the power to the pump for a longer time so it open all of the doors and other stuff.

Why not use a timed relay circuit or whatever? Ya know - the ones with the capacitors!

sorry, i ment 300E. Im in the US, but i think they still have vacuum locks because mercedes are German cars (where my family is from) and i doubt they change it. And i know the pump is under the seat, i ran all the wires for my stereo and its in this huge foam thing. My dad owns a Mercedes shop/ small dealarship, but he doesnt want me putting in all this money into my car, so i cant really ask him about it. But thanks you guys, ill check out the manual to the alarm and program it for a 3.5 second pulse.
