So I got an aftermarket stereo for my 2010 Subaru legacy, the harness adapter it came with is a 14 pin, and the one that's already on the car looks like a 16 pin. I'm trying to figure out what the best way to wire in the new head unit would be. Do I just cut the wires and try to connect them to the right ones? or is there some kind of adapter I can get? Because I haven't been able to find anything online. Pics attached, please help if you can
