Hi, perhaps I can help. My name is***** you have no power at the reverse light wires when the car is in reverse you most likely have a bad reverse light switch or the switch is disconnected. You need to test your voltages at the headlight switch module. Terminal A1 on the module is your reverse light input from the gearshift module. You should measure 12V on the grey/green wire at terminal A1 when the car is in reverse. If you don't have voltage you will need to check the wire at the shifter. If you do have voltage you either have a bad headlight switch module or there is a fault with the wiring between the switch and the reverse lights.

Yes you were correct. It's actually a grey/yellow on the left side but I think it might look like a white/yellow. You need to check your inputs and outputs at the headlight switch.
