So basically i just purchased used illuminated door sills for my L494. Went in and plugged in all of them, noticed none of them are working. Tested the 4 door sills using a 12v tester, and turns out they all work. So now i'm thinking the issue is coming from the car's wiring. I peeked under the carpets in the rear both sides left and right and noticed a few unplugged wiring harnesses, does anyone know what this is? Anyone have a clue why my illuminated door sills aren't working?
