I have white/brown and white/blue left on wiring harness on dual xdvd 9101 on my factory harness i have the blue and orange wires left
You can download the User Manual (including the wiring diagram), from http://www.dualav.com/mobilevideo/xdvd9101.php. Anyway the blue/white cable will be +12V, after the 9101 is switched on, and can be used to power a electronic antenna, a motorized antenna, a amp, etc. The white/brown cable can be connected to the reverse light and would automatically open the panel and switch to rear camera operation when the reverse gear is selected. The wires left on the factory harness can be anything. MAYBE the orange wire is the car-light and MAYBE the blue one powers up an antenna-amp. It should be possible to find out the function of these wires investigating the pinout of former conected equipment.
