Hmmm.
The common colors I've seen are:
White=gnd
Brown=Tail & marker
Green=Right turn & brake
Yellow=Left turn & brake
As evidenced by etrailer.com:

Sorry, but the STANDARD is Green Tailights and Brown RT. For Travel Trailers and Bargman. I KNOW you went to E trailer but that schematic is NOT correct for a 7 way plug. Doug(Master Certified RV TECH) and have wire HUNDREDS of 7 way trailers and Tow vehicles). Where the "tell" that you are wrong is the Yellow wire. This is where it gets confusing. 6 way and 4 way plugs the YELLOW is LT. The GREEN is RT and the Brown is Running lights. White is always Ground. BUT, for American RV Trailers with 7 way plugs, it is how I described it.The other 7 and 6 way(your picture) are for Utility and Commercial trailers, NOT RV's. Doug
