Hello all. As the title states, I'm in need of some information on the back-up lights on my 2009 2500HD 6.0L (I know this can make a difference in the wiring harness) The problem is that I have no backup lights. They don't come on when I put the truck in reverse, they don't shine when the perimeter lighting is engaged, and there is no power going to the trailer plug when there is supposed to be. I have check the fuses and they are good. I have also run a jumper wire to the fuse and the lights come on. I know the bulbs and sockets are good.

Despite what the google machine says, there is no relay on this particular truck. Does anyone have an idea of what the problem could be?

I focused on the two red ones (10 amp?) at the bottom right hand corner of the fuse box that are labeled for the truck and trailer backup lights. I have tested them with the truck running in reverse and they are not getting power. Is there another one that I may have overlooked?

In my mind, the easy solution is either another fuse or a backup light switch. The hard being a BCM or even a fuse panel.

Edit: I have had some time to search various parts websites for a backup light switch. I'm seeing that it either threads into the side of the transmission, or it is integrated into the neutral safety switch.....can anyone shed some light on this for me?
