Best to start from scratch if your unsure :roll: .
Green = speakers
purple = speakers
Red = live (ignition)
Yellow = live
orange = live
Blue = power ariel
Black = earth
Thats on my stereo :shock: .... i just wired yellow and red direct to battery, black to chassis, green to speakers and forgot about the rest.
Just remember... you definately need Red and another live wire connected for system to work... no real need to go to ignition.. but both do need connecting
