Mav,

^nice one^



find a bulb and ground one connection and put a cable on the other, and then put the other end onto one of the cables,
if shine = $true then do begin
writeln('you have found the + cable!');
end;
else writeln('youve might have found the ground, or cable not connected')

why not just open up the plug?
that's all i did

Generally the ground will be black and the 12v will be red, orange or yellow. Or you can pull out a VOM and put the black lead on a piece of bare metal from the car frame. Then touch the red lead to each wire and see which one shows 12v.

If it didn't have the lighter adapter, that would generally be true. All the lighter adapters that I've seen have had both black for astetics. The wires are generally differentiated in some means, one ridged and one smooth, one has a white line on it, etc. You could simply chop off the cord, and plug the adapter into the socket and take a multimeter to it and then match up the wires.
