Hi,
I'm retrofitting exterior door handle lights, but I can not make it work. Tried 4 different leds none of them are working (all of them are not new, bought from two different people)
I've measured a voltage in the plug, its ~11.80V when I unlock a car.
As I retrofitted to rear passenger door only.
I've connected + wire to T20/1, - wire to common ground in door wire harness.
In all door modules activated Byte1 Bit0.
Any ideas what could be the problem?
