Hi, my name is Keith and I own a 2008 silverado 1500LT 2WD. My background is mech. engineering/electronics, and my first job was an electrical mechanic for a european car dealer. Now live in Ontario, Canada and am involved in a new technology loudspeaker industry. Love the truck but ran into some electrical problems for which I am starting to find some solutions, will have some questions and might have some answers.
