w124/Becker "Grand Prix" Schematics??
I recently purchased a 1987 300e with a bad head unit, not requiring code, just in bad shape. Can anyone tell me specifically what each of the four top right poles and five in the middle are? Also, is the prong in the middle bottom ground or alarm related? I noticed that it is attached to a type of bridged harness. Thank you very much for any input.

I wouldn't bother...
Ditch it and buy an aftermarket unit! The Becker is outdated, sounds/performs horribly and will just cause you more trouble in the future, why waste your time and effort? Just my $0.02...

Well, the actual head unit is fried, I was just looking for the wiring diagram so I could determine which wire was which as far as installing the aftermarket head unit I have now.
Consequently, I did finally find the information I needed and if anyone else needs it as well, the coding on the cars harness for the HU is as follows: Purple w/gray stripe = power with headlights switched on with first click Brown = ground Red w/white stripe = power directly to battery connect to the yellow wire of the new stereo Black w/yellow stripe = igniton key in accessory position, connect to the red wire of the new stereo blue/white wire which operates the antenna, connect it to the blue or blue/white wire of the new stereo Of course, the speaker wires are self explanatory with the exception that the rear channel doesn't hook directly in to the head unit....
