Dale, you are totally correct.
There was debated in another thread a while back and I could not understand why persons insisted "There is no standard automotive convention for trailer connectors." I finally realized these persons considered wire colors to be part of the convention, or simply unaware of reality.
The automotive industry has "NO" Wire Color Convention in place for any component used in the automotive industry. But, SAE (Standards of Automotive Engineering) has established several connector/contact conventions for components that are widely used throughout the automotive industry. This includes trailer connectors, light bulbs, batteries and many more.

A normal color code would use yellow for left stop/turn, green for right stop/turn, brown for running lights, etc. Also, red is often used as battery charge, and black is an aux wire...sometimes the black is used as the battery charge wire...also, not all harnesses have a purple wire, or even a black wire, for a 7 wire conductor. I've also seen some that did not have a white wire, and used the black wire as the ground.
Always test by function only, and do not assume that any color code was followed.

This is exactly what I ran into while trouble shooting a dead short on my trailer wiring. After looking at the e-trailer 7way wiring diagram it all makes sense now.
Even though I have a enclosed cargo trailer, the trailer manufacturer has the 7way plug wired as if it was a RV.
They have green as run/park lights,yellow as reverse lights, red as left turn/stop, brown as right turn/stop, black as 12V/aux etc. I had me going crazy for a second, then I broke out my meter and realized what they did.
