    Default GMRC Aftermarket Head Unit Wiring Harness

    Hey guys I have a wiring harness that I purchased and used in my 03 Silverado with Bose package. The wiring harness keeps the factory chimes but does not support onstar. I was planning to install this in my next truck when I was in between vehicles but since my 07 silverado came with a 6 disc changer, I am not going to change the head unit. So anyways if you are interested send me a pm and make me an offer.

    The sticker on the harness reads:

    GM Chimes No Onstar
    "The best things in life aren't things"

    2007 Chevy Silverado Classic 1500
    Ext Cab 4wd LT

    Hey man, Do you know if the wiring harness is compatable with a 2000 GMC Denali, because i also have a Bose stock system in my truck and i have 2 Memphis Audio 12's with the head unit and everywhere i have looked they are asking like $120 for it.
