Hello,
I Just bough a Pioneer AVIC-7000NEX, a huge beast
I soldered most of the wires for the harness but there is still some wires...

First, there is the purple/white one witch should connect to the reverse gear signal wire (where is this one !?!?!) for the rear view camera.
Second the pink one used for navigation system to better estimate your position while in movement using the car's wheel speed. It should go to the car speed signal input (where is it !?!?!)
Third the green wire connecting to the parking brake switch (to prevent film and GPS (?stupid?) navigation to be used without parking brake on. What is the easiest way o bypass this?
thanks
