New to this site.I have a 1983 300 sd Im fixing as a commuter car.I have removed the ignition lock assembly to replace it with a new one.When I pulled the plug off of it,it came apart and the wires came out of it. does anyone have a diagram or the color code to match the numbers on the plug?? Thanks

I have the info for the '82 300SD. May or may not be useful.

30 (2 places) Red
P30 Green/White (light switch)
15 Red/Black (fuse box)
15R Red/Green (fuse box)
15X Red/yellow (fuse box)
50 Violet (preglow timer) and Violet/White (starter lockout switch) (2 wires)

THANK YOU! THANKYOU! THANK YOU! Wired it to your diagram and everything works except the radio and antenna.Got to check with previous owner and see if those worked when he took the column apart.circuit for radio has power.
