quick question. installing a aftermarket deck in my 05 cavalier. now i was told i would need to run a ACC power wire from my wiper fuse to the deck. but my aftermarket harness has a red wire....does that mean my car already has a acc wire to the factory deck? or is that just a usless wire for other GM's? Also it has a orange illumination wire and my deck dont have a orange wire...so cut it off?

Your deck doesn't have an orange wire at all? Sometimes they go by dimmer, lights, etc. also if you have the right harness for the 2000-05, they usually have a speaker box then you can use the red wire. The cheap ones don't have a power wire and I don't know why people cheap out. You also loose your door chimes if you don't have the box so if you leave your key in the ignition or lots on you won't hear anything.

Not 100% sure but on my 99 the red wire is the acc wire, u could also wire it to the yellow power wire and be able to use it without ur key, jus make sure to turn it off so it won't kill ur battery. And yes orange is dimmer. Don't think I used that/not important
