2016 Chevy Silverado factory radio, installing a pioneer DDIN radio. For the life of me I cannot figure out where to hook the red accessory wire coming from the pioneer wire harness to the factory connections. The green 16 pin has a yellow (constant), black (ground) and the other wire for the speakers. I have tested all the pins with the key on, off, accessory mode and door closed and open and cannot figure out which wire in the green connector is an accessory wire or how it turns the stock radio off. Wanted to use the cig lighter but it stays 12v constant no matter what I try to do to see if it loses power. Any advice would be greatly appreciated.
