dentate

I know illuminated front door sills are available on the SQ5. I am considering purchasing either a 2019 or a 2020 Q5 - likely a factory order. Has anyone retrofitted these illuminated sills to their Q5 - I am speaking about the genuine ones from Audi not ones from ebay. I am also wondering if the harness is present for plug and play or would wiring it in be required. Any advice would be helpful...for anyone who has added it - pictures would be even better. Source where to purchase door sills at a reasonable cost as well. Thanks in advance.
