Help w/ HU
Anyone who has installed without harness. I installed an alpine head unit without the expensive harness. the question i have is does this car not have a 12v ignition wire running to the stock stereo? i didnt find one at all. i dont drive my car during the day much so right now i have the alpines ignition wire connected to the car's dimmer, so it turns on at night since my lights r on. any help would b appreciated

so you got no harness at all? not even the $12 one?
well if not, the 12V ignition wire is the yellow one i bealive, then you run your 12V constant power out of the fuse box

the 07 cobalt doesnt have a yellow wire. well it does but the yellow one is for the rear speakers, the constant (battery) wire is red. and i checked all the wires with a voltmeter and i found the dimmer but now ignition wire.
