My 02 C320 has a lot of issues that I'm working through but the one I'm most concerned about is the wiring. I've searched the net for a wiring diagram and haven't found anything so I'm hoping someone can tell me what the wiring harness with brown wires is for as well as the brown and white wires that are coming from the steering column. Since both were dangling under the dash when I got the car, I have no idea where both sets of wires are for.

 

Found out the connector assembly is actually functioning as a busbar for the negative side of the components off of the CAN. Still not 100% sure what the white & brown wire is for.
