2006 yukon/bose audio wiring diagram

Does anyone have a wiring diagram for a 2006 GMC Yukon Denali with the Bose factory audio system. I have some really weird interference problems and I found that the car 's audio system had been modified for an aftermarket audio system and then had the original factory system re-installed after modifications to the wiring harness. I'm trying to bring it back to the original factory installation and hopefully get rid of the weird interference issues. Thanks in advance to any help anyone may have.nazty boy

do this for me if you can? pull out the center cup holder.... check to see if theres any wires cut inside there. another check to see when you pull out the deck in the backl there should be a blue square pulg that goes to the radio this one has to plug into the white one the blue male goes int to the white fem ... check thast out ... what type of interference you got going ??installers do it best. we got the magic hands!
