I bought the Chevy Duty kit for my '53 6500 and enough bulk trailer wire to run to the rear. I'm using the white wire for the brake lights and the yellow, green and brown as usual. I haven't gotten it all hooked up yet but I imagine I'll need a ground strap from the rear of the frame to the dump bed where the lights are if it doesn't already have one.(haven't been under that end yet) I don't know if the hinge point will make a ground.
