It is a piece of cakee to wire radio.

Measure the old wires with a DMM

1) 1 wire is constant 12V to remember radio setting with key is off
2) 1 wire is switched 12V when key is in posn 2 to turn radio on
3) 1 wire is switched variable 12V when parking light is on for dimming. It may not exist with old cars.
4) 1 wire is ground, probably brown as MBZ uses brown color.
5) 1 wire activare the antenna.
6) Speakers wires.

Once you identify all these wires then you should be able to hook up the new radio.
