I am installing a new head unit in my 2000 Cavalier. The promblem comes once it has been installed.?

Question

Once the head unit is installed, it does not turn off with the car. I have to physically turn it off or it will stay on. Can anyone help me with this? I was told I had to wire it to the ac but I'm not sure if that is right or even where to do that.

Answer 1

get a repair manual and check your wiring, also get a different head unit, also the unit should turn off with the car because if you wired it correctly then the power from the battery to the stereo should stop along with the car

Answer 2

The red wire on your new radio needs to be wired to a source that only supplies voltage when the key is on, an accessory source. Your factory harness does not have this switched source, so you will need to run it to a switched source in the fuse panel.
