Just wanted to know if anyone has the color code for the factory harness for the 2003 silveraldo. can i connect the radio without the chimes? Please help.

2003 to 2005 is this from what i have seen which is all same except ign and ill and amp turn on
Radio 12v orange +
Radio Ground black/white - radio harness
Radio Ignition (Class 2 Serial Data)
Radio Illumination N/A
Factory Amp Turn-on pink + radio harness
Power Antenna N/A
LF Speaker +/- tan - gray +,- radio harness
RF Speaker +/- lt. green - dk. green +,- radio harness
LR Speaker +/- brown - yellow +,- radio harness
RR Speaker +/- dk. blue - lt. blue

but i would go to circuit city or best buy or get on ebay and buy a harness and not cut the factory at all. and make sure the radio does not say RDS on it, if it does you will need extra parts. the metra harness number is MET 702003 or MET 802003
