1983 Mercedes Benz 300d ignition wiring

usually when you replace the ignition switch, you take one wire off the old one, and hook it up to the new one until all the wires are on the new switch... when you say 1 or 2 wires fell off the car, and not the switch, im assuming all the wires that were connected to the old switch are on the new switch... the 1 or 2 wires fell off in the column or somewhere else? also, what are the colors of the wires in doubt? should be a solid color with a stripe... being an 83, my resources are VERY limited...

I have my private manuals for that particular vehicle, tell me the wire colors and I will tell you where they go.
