Hi all, any help is greatly appreciated.

I may have to take the car in to service but I don't want to if I don't need to.
I purchased OEM illuminated door sills, and after installation I’m having trouble getting the passenger side lights working. Driver side has no issues. It should be plug and play from what i've read..

Just to check if the passenger side part wasn’t defective, I plugged the passenger side part into the driver side port and it works fine so I know it’s not the part with the issue. I also noticed the puddle light, and ambient lighting on the passenger door not working after installation. So I think its a wiring issue. I've already checked the fuse box and dome lights and they all work and no blown fuses.

I just don't know where to start and theres so many layers to this problem. Any ideas? See pics below. Thanks for any help.
