LED Tail light upgrade issues




So I bought the upgraded led tail lights for my 2007 Mercedes s550 from fishfakes on eBay. Unfortunately I get 1 error for rear right side marker light. The weird part is that the light is actually working. I have read on here that a lot of people have not had a lot of success with the tail lights they bought from this particular seller. So my question if I add a resistor to the wire on the harness responsible for the rear right side marker that should fix my problem , right? So doesn’t anyone know which wire on the harness coming from the car do I need to add the resistor to? I have checked everything from the pins to the wires making sure that they are making contact with the tail light harness but seems that nothing effects the error light. Any suggestions?
