If you add the information on what year of car we are talking about to your signature we could tell you a whole lot more.... And typically the power lead to the reverse light is the one that's not black.

 

thanks for the quick response.


It is a 99 honda accord, automatic transmission coupe.

The dealership said the speed signal wire is a blue adn white wire, comming from connector B and it T's off.

Generally these are behind the cd player, or at least accesible. I just see a lot of blue/white wires.

 

You could trace the wire from your VSS on the transmission or just clip onto it in the engine bay.
