so I am starting to wire the OS-2BOSE to the z1 harness and have a few questions, I am keeping the Bose and onstar for now. comming off the deck I have a blue and a blue white wire. according to the PAC OS-2BOSE instructions I have to wire the blue/white wires together, and the blue is for the antenna lead. My questions is what lead can I use to turn on my amp. do I just splice into the blue/white wire?

 

thanks for the help
