I have a Pontiac G5 that I installed an AVIC 8000 NEX deck in. I set up the parking brake gnd using a relay so that's all good. I hooked up my cam to the back up light wiring and ran the video wire up and plugged into the brown connector. It works using the Camera On function when I put the car in reverse. But, when I put the car in reverse with the Camera On turned off and of course the first thing I did after installation was switch Backup Camera to On, in reverse I get no change. The reverse wire, based on being hooked to the back up light, shouldn't I be able to just hook that into any constant 12V wire and function?

 

Any assistance on a current site that I can do a location search for the VSS wire on my model would be appreciated as well. The links Im seeing here lead to broken pages. Thanks. Ill read more here on changing and modifying backgrounds and splashes.
