Sounds solid.I'll go ahead and troubleshoot it down to the most basic, but DD claims they test each set of lights before boxing up. And the fact that the backlighting works using the harness provided seems to indicate that the grounding is fine and the lights are operational.
My test on the main wire, I removed the butt connector that I added to replace the wrong spade connector that they sent it with. I did so to remove the variable that the crimp on the butt connector was wrong.
I end up making my own harness using mostly supplied wiring and wrap at times.
You shouldn't HAVE to.
But it be like that sometimes.
It's why I have a wire spool rack, loom spools, rolls of heatshrink.
Sometimes supplied harnesses are legit perfect.
Often times though, not so much.
I've found grounded out terminals, uncrimped connectors, broken wires in supplied harnesses (not necessarily/specifically this particular brand) before for stuff. And usually the harnesses are a mile too long or 2 feet short. Or even worse, inches short when routed cleanly.
EDIT: not really sure I am helping at all with your root cause. Just more spitballing/ tales of trial and error more than anything. Hoping maybe something in there jumps out and give you an idea of an avenue of attack on it.
You are a quite capable guy, so probably already past anything I've mentioned.
Just with me, personally, I've found most supplied harnesses to be lacking in some shape of form.
