Hello,

My speedometer does not work anymore (self-test @ instrument cluster OK, I fitted a new speed sensor), I have an issue with the wiring from the vehicle speed sensor (rear differential) to the speedometer.

Did someone already replace these 2 wires because they were damaged (brown/red + brown/black)?
I am looking for hints where they were damaged and their mapping (I just have a jack (+ jack stand) so I am not too comfortable to look for the cable so any hint will help !).

Thanks in advance.
