I recently installed the curt hitch on my E90.
The problem is that I don't know how to install the curt "56146" trailer wiring.
I have researched a lot but did not get any instruction on installing trailer wiring.
I have not been able to identify any wiring.

HERE IS THE COLORS FOR LEFT SIDE TAIL LIGHT. PIC IS ATTACHED.
BROWN
GREEN
PURPLE/YELLOW
YELLOW/BLACK
YELLOW/GRAY

HERE IS COLORSFORM RIGHT TAIL LIGHT. NO PIC YET.

I know people have installed this wiring harness on E90.
I will Appreciate any guidance to help me install this wiring in my 2006 325xi Sedan.
I WILL DO DIY WITH PIC'S IF I'M ABLE TO INSTALL IT IN MY E90.
