You will only have to worry about the chimes and alarms on an 07 and up (unless you have onstar and all the extras). I got the $120.00 harness and the chimes quit working after about 2 days. But the right side speaker goes quiet for a few seconds instead, so it all worked out i guess.

I bought a wiring harness off ebay for only 6.88 shipped works great but I did lose my chimes which is fine with me. they are annoying.
