Review on Metra 70-2003: Superior Radio Wiring Harness for GM 98-08 Vehicles by Jack Collins

Perfect for those who don't have to worry about losing the factory ring. This is an advanced installation item and it is recommended that an additional fuse with the red wire connected to the fuse box be used instead of the supplied gold item connected to the existing fuse. Finding the ACC cable is not easy. You will see many shoppers who cannot get their devices to save the date and time settings. However, this is due to an installation error. I installed 2003 Silverado. This applies to non-Bose and non-Onstar systems. Notice for Chevrolet vehicles. Silverado, Tahoe, S10, Suburban, etc. you will lose factory warning tones and the ability to turn off the stereo when the door is opened (maintains power to the accessory). If you want to keep these features, you need the Metra Chime GM add-on. Its cost is over $30. This is an economical solution that works great.
