2005 Silverado Bose Soundsystem Help

[rjacksonh03]

I have a 2005 Silverado 2500 HD with the LT trim package and the Bose Soundsystem. Problem is, the previous owner wanted to put in an aftermarket radio and jerry rigged the hell out of it. Most of the wires were crimped off and he ran 2 wires from the radio directly to the right speaker. Radio codes are UQ7 and UC6. Requesting the wiring diagrams from the radio to the bose amplifier and the diagram for the amplifier to the speakers. Help would be greatly appreciated.
