Okay, feedback:
My 1995 E320 came equiped with Becker 1492. There's 2 oem wiring harness going into the back of the becker unit. one of them controls the cd changer, the other houses the rest of the wires.
Using a wiring diagram i got from a thread somewhere on this site, i was able to hook up all the connections without any issues.
Snaked the wired microphone underneath the center console and then up the driver seat, i clip the mic right next the the headrest. Everything is working perfect now and it only took me 2+ hours.
Another job well done!
