Review on 🎵 SCOSCHE GMSRCL2 2003-2012 GM Class 2 Car Stereo Replacement Interface Control with Chime (Optimized for Class II Data System) by Cory Spence

Works well. I have a radio and my bell in my car. A note: on older cars (I have a 2004 Chevy Silverado) the wires are not the same color as the factory harnesses. It was very confusing for a beginner like me, but they line up correctly even if they are different colors. Both schematics can be found online if you're willing to work hard, but you really don't have to. It works the way it is. This information is very hard to find, so I'm sharing it here. Using a kit without a black box also works, but you have to run a hot wire to the fuse box (which I don't even want to do). ) and you lose all your warning signs.
