Searched and came up empty handed...maybe Im not using the right words. Someone has to be fed up leaving their lights on b/c there is no buzzer when you turn the truck off...Ive done it 3 times in the 3 weeks Ive owned it. Ive caught myself each time...but its only a matter of time before I don't. Should be fairly simple though...does anyone have a diagram for it or a writeup of some sort?
