Red/white is the battery 12volts
brown is ground
white/blue or gray/white is interior (dash) light
on the others get a volt ohm meter and check the resistant between each wire, to an the others if it moves then there maybe a speaker but keep checking because there could have two speakers using the some ground, if you are putting a high power radio in each speaker needs its own ground. the safety way is put new wires for the speakers.

just compared what I gave with another site I use, same layout. Sounds like someone put their own wiring harness on the stereo that was ripped out. (most likely was an after market unit) Best of luck.
