The orange is a constant 12+, and I am pretty sure the corresponding brown in that plug is a ground. In the Aftermarket harness adapters, the spot where the brown is is left blank, so it must not be absolutely necessary. The lowermost plug in the radio pictured is the power, with yellow being switched 12=, grey is illumination, and black is ground. The other two are speaker plugs. Seems like the lt. green/dark green and grey/tan are fronts, and the yellow/brown and lt. blue/dark blue are rears, but I may have the front and rear colors backwards.
