2011 Chevy Silverado radio wiring help

[tbone1014]

Can anyone help explain what the wire on the two plug go to on the back of the radio. I bought an aftermarket radio to install and the wiring harness but it seems like some of the wires on the new harness does line up wit the wire on the factory plugs. i have searched and found so many different wiring diagrams im confused at this point. I did look at the tag in the glove box and I think i have a UQ3 radio.
