Need help rewiring a stock MCS Head Unit
Hi guys,
I just bought a 2003 ML500. I noticed that the HU didn't work. After removing the HU, I noticed that all of the wires had bee chopped. Thankfully, the harnesses were still plugged into the HU, but I had to pull all of the stock wiring out onto the driver's side footwell. Of course they had wire nuts everywhere. Unfortunately I can't seem to find a standardized color code.
The HU P/N is 4 163 820 20 86
The Model is MCS
Model number is NV4BN110
Does anyone have the (colored) wiring diagram for his HU? All I'm trying to do is reconnect the factory wires (without ruining anything).
Thanks in advance!!
