I have searched the forum up and down, including google as well as forum search tool and for the life of me, cannot find anywhere that speaks of the 2019 Silverado ignition wire location/color to tap into, enabling a control box to power on alongside the sound system powering on. I know my truck has the Bose sound system if there’s an amp that I could tap into for power possibly? I’ve searched the forum for the sound system topics and haven’t had any luck there either. I’d greatly appreciate any assistance in location of this wire. I apologize if this does not belong in this sub forum also. Sent from my iPhone using Tapatalk
