so i'm in the process of my install and i'm not exactly sure which wires to cut and solder. now i used this guide as a reference to the wiring harness.
Subaru WRX radio harness pin-out
my question is which wires do i connect my aftermarket harness too? i see two harnesses, one with only solid colors (that was connect to my stock HU) and another harness further back (the wires that connect directly to speakers, etc) with solid and stripe wires.
i don't really have experience with wiring but i'm leading towards splicing the harness with the solid/stripe wires and directly connecting my aftermarket harness to that, color to color
