theres no problem!
u just need the plug of the limo/touring/coupe
its a centralplug, where all 3 lights are included.
now my tip, go to a "schrotthändler" (wastemonger???), search for e36 lim/tour/cou and cut out the plugs.
the wire coulours of your actual plugs are the same like the new. connect them and now u have the plug that u need.
one tip for free, i dont want toe be impolite, but learn german.
u cant expect service if u dont speak our language. not everyone is able to speak english well, or maybe doesnt want to.
if u need help, ask so that everyone understands u.
