Ok, so I bought the adapter that allows On-Star and the door chimes, etc to work and I'm not having a problem there. However, by replacing the factory radio, I lose the date functionality of my DIC. I bought a harness to relocate my factory radio to the trunk: 2000-UP GM Harness to NonFactory Stereo Adapt/Retention - Mobilistics
The only problem I have now, is that I have no clue how to route the harness through the car into the trunk. I've never done anything like that before and I have no clue as to what path to take, I need to know what components I need to take apart and exactly how the harness should be routed. Would someone be willing to give me a detailed explanation of how to do this? Pictures and/or diagrams would be extra helpful. Thanks!
