Review on 💡 Metra XSVI-9003-NAV Accessory Power Retaining Harness for Non-Amplified and Non-OnStar Systems by Ynot Karlen

Good kit to avoid cutting the factory wiring. All factory functions, such as B. delayed shutdown, are preserved with proper installation. I recommend proper installation with solder joints and shrink tubing to avoid problems from vibration etc in the future. You already have a disconnect from the factory wiring harness in the car because of this kit, so you don't have to unhook the radio yourself unless you're changing head units. Cut and solder at this point. Lots of things that fit behind/around the main unit so you may need to make extensions to give you enough flexibility to fit everything.
