[QUOTE="wet_rat, post: 6915895, member: 607886"] 08 Hummer H3 installing Valor NVG-720W with GMOS-01 to retain Onstar and door chimes. I have NO factory amp but installing DSC-5125 for fronts and rears and Nine.1 for sub. In the section "for aftermarket radio and amplifier" here's how it reads FOR AFTERMARKET RADIO AND AMPLIFIER (See wiring diagram on page 6) CONNECTIONS TO BE MADE ON THE 14 PIN HARNESS: 1. Connect the red wire to the ignition/accessory wire of the aftermarket radio. 2. Connect the Orange/white wire to the illumination wire of the aftermarket radio.
