Help! pinout for 1993 500E Ignition/starter switch (S2/1)

[ke6dcj]

I checked both my paper and CD-ROM factory manuals, and the schematic for the ignition/starter switch (S2/1) is missing three (3) wires.

Specifically, it is missing the following pinouts on S2/1:

15R
15X
P30

And yes, I do have three wires extra wires (connector came apart) which are:

PK/YL
PK/GN
GN/WT

FWIW, the two pink (PN)-based wires are at least 10-gauge, and the green (GN)-based wire is a 20-gauge.

Anyone know, or have access to the Mercedes factory service site ?

FWIW, this is for a 1993 500E.

Thanks,
