flaw

I just bought a 1989 560 SL. In 1996, Mercedes send out a bulletin which basically disable the roccker switch in the centre dash which allows one to control the antenna height. Checking out the antenna, there is a 5 pin connector and only 3 are used.
Position 1: Brown: I assume thats ground
Position 2: empty
Position 3: Red: I assume that's power
Position 4: Blue/white: what is it
Position 5: empty

2 wires are not connected
Blue/Yellow
Blue/Green

Can someone help me to reactivate the control switch to its original intended function?
Can someone e mail or post the origiginal wiring configuration?
can someone be nice enough to look at their antenna with a working rocker switch and let me know the wiring positions of these wires?

Much appreciated.
