Review on Enhanced Car Stereo Installation Kit: GM LAN29 Buick Chevrolet GMC Pontiac Saturn with Dash Kit, Wire Harness, and Antenna Adapter – Important Notes Inside by Ronald Noel

Extra wire you are supposed to run to the fuse box. This is too much work. I took my test bulb and found the power wire to the airbag bulb, which you turn off by removing the panel around the radio. I plugged it in to turn the radio on and off with a key, a much easier solution and a lot less time. I also took one of the wires that wasn't being used. It seems that the amp wire soldered it at the site of the liquidation on the radio. On GM vehicles, this is indicated by a dimmer in the wiring diagram. This way the radio is automatically muted at night.
