What are Wiring Colors of the 7-Way Trailer Wiring Plug # HM20041
Question:
The Hopkins 20041 7 blade connector is shown on your website as RV wiring. The Hopkins website lists it as Auto industry color code . Which one is correct ? I was looking for pn 20045 6ft but the 200418ft will be ok if the color code is Auto. The auto industry standard matches my trailer colors and would make the wiring more organized.

Helpful Expert Reply:
Easiest way to explain the wiring colors of the Hopkins harness part # HM20041 is for me to just list what the wires color functions are as follows.
White: ground wire
Yellow: left turn/brake light
Green: right turn/brake light
Brown: tail lights
Purple: reverse lights
Blue: electric brakes
Black: auxiliary power
This matches the SAE standard colors like what you see in the attached diagram.
