Judging by your other posts this is for your 87 GTA. If so, you should not have to change anything besides maybe an antenna adapter. The radio harness should be the same for the late model radio as the harness in your car. Just plug and play.

They make an adaptor harness you can use instead of cutting your wires.The 3 big plugs go in one end and the other end has a 21 pin plug which is what the newer radios use.You will alos need an antenna adaptor as the newer radios have a smaller antenna plug.I had to do this in my 86 iroc when I installed a mid 90`s delco cd player
