Hello, I'm in dire need of help. My 2009 Aveo sedan's head unit wiring was clipped, and i need to figure out what each wire is and the number it would go to of if you could tell me what they would be, gm lan1 , gm lan2, pwm+, pwm-... so on and so forth. I'm not able to put in a new head unit til i figure this out so if you could post it on here that would be alot of help thanks! i also found a 2009 hatchback, but the wiring isnt the same.
