You replaced a wiring harness on a 2015 already?

 

You can get all speaker wires from the drivers kick panel. I'd highly recommend not using that style conector as water will get into that trough and you are going to introduce green rot into your speaker wires. Warranty will not cover that in any way, and as a heads up the wiring harness you are tapping into is one piece from the firewall to the 3rd brake light. Picture added to discourage this type of modification.



Really fun to replace

 

Please don't say you can do something without elaborating on it.

Driver side kick plate has speaker wires for both sides?

 

Yes. You can get all 8 speaker wires from there as needed.

 

Love the back window sticker, saw those one facebook
