2012 ML trailer hitch wiring
2012 ML 350 BluTec
I'm installing a factory hitch and need some assistance with the wiring harness.There are two connections i need help with. On the brake control harness there are 2 connections, one is a small black/white wire with a pin connector and another small female two pin connector w/ brown and brown/red wires. was wondering if anyone knows where they connect or can send me wiring diagram.
Also on the controller,what wires connect to the blue connector? Hope I attached the images correctly.

Installed my facory OE hitch kit last weekend,labor intensive but got it done.
Took to dealership for recoding,no sam change required. It even added a
"SUV connected to a trailer" icon displayed when reverse camera is activated
and changes camera angle down for connecting to trailer tongue.
Total cost: 870.00 for hitch kit, 20.00 for adblue tank bracket, 236.00 for dealer recode, 1 1/2 hr labor.
Here are some pics.
