First thing first. You just using the dash speakers or do you have any in the back or on a soundbar? The dash speaker wiring is easy. Just find the wires leading up to the speaker and match those colors in the harness where the deck goes (should be the lt grey and blue pairs). If you are hooking up rear speakers, those are going to be the green and purple wires. I'm not 100% sure which ones are left and right, but it shouldn't be too hard to figure out. Hope this helped.
