I recently bought 2024 oem tailights to replace my 21 halogen tailights. I got a harness for them aswell that connects to my original tailight harness. Im having issues getting them to work properly. The drls only turn on when i unlock my car with the key fob but do not turn on when the car turns on nor do they turn on when i lock my car with the key fob. The turn signals dont work either. The only thing that works is the brake light when i press on the brake. Im new to all this and dont know a lot about harnesses and wiring but i would like to know what the issue could be. Would i need to use forscan. I could take pictures if needed if anyone could help

Post a photo of the original tail lamp, there are 2 versions of the non-LED tail lamps which depending on what you have may be the cause why your 2024 LED tail lamps are not working properly.
