Newbie installing pre-Retofitted RLX LED lights

I purchased a set of RLX-retrofitted 99 Miata headlights (they were private purchase, not through someone some vendor building them no they were as-is, sadly). Passenger side works beautifully. Driver side, when we initially tested it, would power on for about one second and then shutoff. After a handful of retests, it stopped turning on at all.

We did attempt to power it with the working-side's ballast and it did not come on still BUT the ballast have different model numbers, unsure if they are compatible.

What would be the best method of testing from there? We did cut a hole so we could look inside the housing to see if there were any obvious wiring issues/cuts but nothing was apparent.

Thank you in advance!
