hello guys I ended up in total darkness the selector does not speak with the box ... I checked with the oscilloscope can le can h but they seem to be okay ... the selector flashes as well as the gears in the instrument panel ... I am passionate and after a year of research I have tried but there is something that escapes me also because pinout change I'm sure it's okay but selector I don't know ... selector of the dq250 is different from the dq500?
