Does anyone have a diagram that confirms what colors coordinate to what positions on the factory installed trailer harness? I'm trying to locate the correct color for the reverse lights (center pin of the 7).

Hmmm I thought I'd at least find a couple people with experience. Pics attached. Based upon a few diagrams I've located I'm leaning towards the reverse lead being the purple wire due to the location in the white harness plug as compared to the location on the diagrams.

All signs pointing to Purple for the reverse circuit. This circuit has it's own 7.5A fuse, which will be great with the 1.45A load I'm going to apply to it. Not going to reveal the full details just yet, but let's just say that 1568 raw lumens should help!

Well, the reverse circuit on the trailer wiring harness is NOT purple. I did find that yellow is the correct wire which goes against everything I found in my research. More to come later in a new thread now that the install is done.

For those that are curious, here are my findings for the wire coloring. Keep in mind that I was looking for reverse, so brake and reverse were the only signals that I tested.
Findings:
Purple - always on
Blue - nothing
White - brake
Pink/red with gray tracer - brake
Green- nothing
Yellow - reverse
