I have an 03 Escalade WITH the Bose system. I got a new head unit (Dual XVM296BT) and got the Metra GM11 wiring harness so I could use SWC. Can someone tell me which wires are KEY 1 and KEY 2? Although I couldn't locate the wires, I still wanted to make sure the radio worked. But when I plugged it up, the radio came on and the speakers did not. I read somewhere that I may have blew the old amp, but I plugged in the old head unit, the speakers worked just fine. Could someone lead me down a good path to start troubleshooting? I have been Googling all day and can't come up with anything. ANY help is greatly appreciated...

Welcome to CF !!

The original head unit is part of the car's serial data bus, content theft, TheftLock, and security systems. Maybe there are other special jumpers and connectors required to keep the rest of the sound system and many other features operational.

Talk to the guys at Crutchfield in Blacksburg, VA.
