There are 2 harnesses in mine. A grey one & a black one. Sorry I can't remember which is which. I think the one with the brown wire was the grey one. Hopefully this will help. Crutchfield has great instructions. I ordered my stereo there & I soldered the harness the night before I installed my stereo & it was pertty much plug & play. Took about an hour from start to finish to remove my old stereo & speakers and install the new stuff. All the adapters,installation kit, & instructions were included.
