I was wondering if anyone knows or can help me. I am upgrading from a 5.0 to an 8.4 and I pulled the headliner down and installed an oem antenna that all of my other chargers have had with the nav and sat radio. My 17 down have one, but it has a yellow connect under the radio of the headliner where I drilled and installed the new antenna. When I pulled the radio out there is only a blue connect in the dash and I can't seem to find where the end of the yellow one went. I did order a new yellow wire harness for the whole car, do I need to install that to make it work or is the location behind the dash or under the glovebox. Thanks
