There, I had to drill a hole in the angle bracket welded to the frame that the rear of the cab body mounts to, and then used a small grinder on my dremel tool to take off any paint/grease/dirt to ensure a good ground. The mount has a big rubber doughnut that cushions the frame/cab interface. The bracket is aout 4-6" to the rear of the hole in the kickplate. I have a Knukonceptz digital power distribution block, and with the Big 3 (or 4) I have 14.6/14.7 constant volatage when the engine is running. It drops to 12.4V when the engine is off.
