NBS Silverado Battery Drain Fix

2007 NBS Silverado would have a dead battery if let sit for more than two days. Or if I would leave the flashers on for more than a couple of minutes with the truck not running. Found that the radio had a parasitic current draw of about 3.5 Amps. Instead of buying a new radio, I figured I would just put a relay in to kill all power to the radio when the ignition is in the off position. Hopefully no more dead batteries!
