I checked the Stickies but they're quite old and outdated. The other day, I was shopping around for a new radio and I noticed there was like 10 different adaptors for the radio, all made for GM cars and Cavaliers is on the list on the packages. They all have different price ranges too, but by the same brand. Does it matter which one I get? I'll most likely go with a Pioneer head unit...just really confused on the adaptors. Incase you guys ask, I do not care about the door or seatbelt chimes.

It would help if we knew the year of your car. The stickies aren't outdated or old, they're just as pertinent.
