I thought that when I ordered my 02 crew cab Dmax with the HD trailering package and Fifth wheel provision I had everingthing I needed for hauling trailers. Problem, I hooked up a new Wells Cargo trailer, it has auxilary 12 volt lighting. I know the plug on the rear platform has a 12 volt lead. It is not getting juice. I have tryed to figure it out with no solution. I don't want to make a trip to the trailer place if I don't have to. Can anyone help I know it is probally a simple solution. Thanks in advance.
