Brown is solid (unswitched) ground, while brown/white is switched ground.
Black is switched power.
Black/blue is instrument light circuit in this case.

You might want to consider rewiring the lighter. It is normally switched, 
so that you lose power to the lighter socket when you turn the ignition 
off. Some people prefer a constant-on lighter socket.

I went to an auto parts store and bought a three-outlet extension cord for 
the lighter socket. I cut the lighter plug off the wire, and wired it to 
the heavy power and ground wires that feed the stereo amp under the cover 
by the right seat. (I would strongly suggest an in-line fuse here!) This 
gives me three unswitched power outlets for the cell phone, the GPS and the 
laptop.
