I'm looking to add a switch for the VSS input on the Nav unit. Been looking through various online resources, but I'm seeing some mixed information.
Trying to verify the correct wire, either by connector-pin location, or by wire color.
Anyone happen to know for sure?
While doing an audio install, I needed to find the vehicle speed signal and illumination wire and there were multiple threads with conflicting information so I made this picture to depict the location of both wires to help people in the future.
