2 trucks later and still going!
I bought this switch box back April 2nd 2012 and its still working great. Out lasted the first truck and it's doing great in the second truck. I have a 2013 Silverado and it's mounted on the roof console and relay box under the passenger seat. The protection circuit works on this thing too. I had a trailer warning light wire get damaged and the control panel diagnostic red light showed me I had an issue. Sure enough, blew the fuse caused by damaged wires and after a quick splice and new fuse, up and running again.
