2018 Dome Overhead Light

[baddog2010]

Does any one know or can direct me to locate the voltage pin-outs on the Rear Dome Overhead Interior Light? I had the overhead panel replaced and now the rear light wont work. It worked fine before panel replacement. Front overhead light works fine in all settings. Appears the overhead wire harness looks to be a one piece so I think not an 'unplugged' coupler. Odd that the LED circuit would suddenly go bad, question the repair shop gave me a bad LED panel. Don't want to pay $65 for another panel only to find it not be a bad panel. No returns on electrical items. I cant seem to find a volt diagram else I'm just not asking the right question.
