Need help to connect central locking button

I want to add this central locking button (the fourth from left) to my car. I found some instructions on a German website, but cant get it to work.

So I'm wondering if any of you guys know where I should connect the cable from the switch to the central locking system? Anyone done this?
 
Discovered now after hours of testing that the button had a loose pin inside... So I might have solved it.

Some more info, I've connected ground to the brown cable, +12v to the blue one. The blue/light blue is connected to illumination power. Then there's two wires left, the yellow/black one gives 12v if i press the button down. The black one does nothing, I believe that cable is for the red lamp in the button, and it does not react to any button presses, this one is probably connected to the IR lock in some way.

So, to where do I connect the yellow/black one to actuate my locks?
 
I tried a bit more yesterday, but could not get it to work. I have to reassemble the interior today and will have to continue with this later.

Thinking about adding a China keyless entry module and use that, I'll research a bit further. Updates will be coming!
 
Need someone with a late car ...think it was standard on Limited models . Arnt might be able to help . Good feature to have !
 
I work on that for a while on my '92 500... Door look works perfect like that, but some Alarm System trouble.. :(


Switch:
Pin 1 = +12v
Pin 2 = dashboard Light (Gray/Blue)
Pin 3 = connection to Realis
Pin 4 = Red Led (not used)
Pin 5 = Ground (Brown)

new switcher Relais next to the Vaccum Door Pump:
87 : connection from switch
87a: original Signal from Door/Look Switch (I think was blue)
30: other side of "87a"
86: Ground
85: key +12v

Still working on that Alarm System Problem.. Mopf 1 got some other Alarm System Box than Mopf 2, no upgrade possible! :(

Well, I am a vegetable on electronics, but my Limited has that switch and it is located in the shifter console panel. I am stripping the aftermarket audio/handsfree/alarm/TV/GPS now, so I can have a look at the wiring for that switch. I think it is 2-3 types of that central locking switch and my car has # 202 820 40 10
