Hello all, I've looked everywhere for the diagram behind my 2015 Silverado 2500 LTZ with Bose. I am looking for the Front Door speaker wire color to hook up my Line Output Converter.

I removed the dash and radio and there are 4 main plugs of wires. I found online where where the Yellow and Yellow/Black wire were the front, but there are two different plugs that have both the same color wires. Side note, the wires are Black with yellow, not yellow with black... At least on mine..

Any help greatly appreciated.
