 Auxiliary Input for 2003 Mach 460
So ive been searching the forums and have noticed a lot of people installing the PIE Auxiliary Input to their factory mach 460 or shakers. I also want to do this but I am confused in what adapter to buy on their website, i dont know what pin my head unit it and ive noticed that it makes a big deal. Also i have the 6 cd changer so i dont know if that changes anything. Ive seen the sticky for the newer models, would that work ok with my 03? Any help would be much appreciated. |
