RADAR DETECTOR WIRING/95 E320
I'm sure you will find switched 12V in the overhead console. My 95 C280 did when I hard wired my Valentine 1 and your car most likely is identical. All you will need is a voltmeter. I can't tell you which wire it is because the car has been replaced by a C320 which does not have a switched 12V source in the overhead. Control Area Network and all that.
