Hi everyone! I've searched extensively but can't find the answer. Does anyone know which wires are +/- and if there is left and right from the Beats subwoofer harness? My 2018 colors are different from the 2014 wiring sticky. The sticky says: Subwoofer (+/-) gry/brn - dk grn/brn (1); gry/wht - dk grn/wht (2). My harness is grey/brown, grey/light brown, grey/white, green/white. Thanks in advance.
