Hey guys, I am thinking of changing out the head unit in my 2010 base GT with an alpine double din and the metra kit. I am curious is I need the scosche wiring harness.

I don't think I would need that one since I dont have any door subs or steering wheel controls.

Please let me know because if I do need it I will probably just go with a CAI.

Thanks.
