I am installing an AVIC-D3 and can't find the Amp Remote wire (Blue/White) to signal the amp to turn on. Anybody know where the wire is on a 2004 Silverado 2500HD SLT.

Do I have to wire from dash to the amp under the center console??

Can I wire the blue/white wire to ACC power?? or is the blue/white Amp Remote Wire a specific output.

Appreciate it...Thanks.

Sounds like you are not using the correct interface module. You need one that is specifically made for the GM Bose system in your truck. One would be like the Peripheral GMAH24B. When wired correctly, this unit (and ones like it) will turn on the amp for you since it is a digital signal.
