2003 Toyota Tundra radio wiring diagram

I am wondering if anyone can tell me the wiring diagram for the radio of a 2003 Toyota Tundra.  I am putting in an aftermarket stereo and to do that I have to take out the factory amp.  The wiring harness for the truck has got a( +) and a (-) dimmer wires on the connectors.  My radio does not have connectors for that.  But my radio has an illumination wire that connects to nothing on the wiring harness.  What do I do?  Also there is another connector with 3 wires that connected to the factory radio but has no use ( I think ) on the one I am installing.  What do these wires go to?  If anyone can help me with any of these problems it would be greatly appreciated.  Thank you!!!

Notes:

*1 It is black on the 6 cylinder models, and blue/white on the 8 cylinder models, at the instrument cluster. On the 6 cylinder models the black wire is also found on the drivers side of the motor at the diagnostic connector. On the 4.7L V8 can also use BLACK/ blue at coil #1 on the drivers side.
