Trying to install aftermarket unit in car and the old one factory was cut out. Ive replaced all fuses ive found to be blown, wited the speakers up, bit im struggling getting power to the unit, my multimeter isnt reading anywhere for an ignition wire either. Im just stressed about this ishh. If anyone has a diagram or could tell me if all 7th gen malibus are wired the same, its also not a bose/amplified system. Thanks!🥺

Accessory power is not supplied in the factory harness. Some adapter modules will provide you with an accessory. If you don't want to spend that much money, you can run a wire from the ignition harness brown or check the fuse box.

My ex once told me I have a perfect face for radio.

Thanks, so i guess my next question is, how do i get it powered up, all i have to do is connect the constant and the ground, along with my speakers? I could post a picture of what i have going on if need be,but it wont be till tomorrow after 6pm.
