Wiring harness ?
 

I was just wondering if the cobalt's head unit works the same as the 03' cavaliers. When I put a system in my cavalier I had to leave the odd head unit in the trunk because of the power or something like that. I'm sorry for the bad explaination, I'm not very good with audio terms. Basically I'm looking to put a system in my cobalt now and I'm wondering if the cobalt's head unit is hooked up the same way? So in turn, would I have to hooked the cobalt up the same way I did the Cavalier. Also, is there any online tutorials on how to take off the dash to get to the head unit. Thanks a lot for everything guys.
