Question about Car Audio & Video
You will need a voltmeter. Normally red is power, black i ground, yellow is memory power. the best way to know for sure is to use a voltmeter to test what each wire is recieving in power and when. If the key is off then the wire that has 12volts dc is for memory and the main power wire should be at 0volts dc. When the key is on that wire should have power now. the ground will be black on that car. Good luck.
