What do i do when i got wires left from the ones that used to be connected to the radio

like dimm lights and lights on input ??

I'm not sure about what wires you have left over. One of those wires probably dims the lights on the HU when the headlights are turned on. Other wires, like power antenna, don't need hooked up (unless you have a power antenna). You can terminate these wires to prevent any shorts and just leave them hanging behind the HU.

Orange = Memory (+12v constant)
Yellow = Ignition (+12v switched)
Black = Ground
Gray = Illumination
Brown = Dimmer
Pink = Power Antenna

So "dimm lights" is probably brown and "lights on input" is probably gray.

ok thanks well its plug and all and works fine
very happy its my first stereo installation and it was easy
