I’m in need of little help!! I put up a 12’’ nilight for a back up light. The problem I’m having is it’s wired up good. But when I hook it to the rocker switch it will come on. Then once I turn it off it won’t work anymore. I got one ground from the light hooked to the ground on the switch. The other ground has the ground from the fuse box. Then I have a hot wire coming from the fuse box and the hot wire from the light going to the correct spot to where it says to hook them up. I’m using method A. Any and all help is greatly appreciated
