Back-up Light Connection
Does anyone have a wiring diagram for the 05 SD PSD? I am trying to find the back-up light wiring coming out of the Central Junction Box. I have installed a back-up camera. I had to wire it to an Upfitter Switch, but I would like to wire it into the back-up lights.

It's fuse #27, but that will not do you any good. That is just key-on power for the lamps. You need to pick-up the power after the back-up light switch if you want it to trigger the camera. This is a black/pink wire. If you have an auto-dimming rear view mirror, you can find the black-pink running up to it. You can also find it down on the side of the tranny if you have an automatic.
Also in the fuse box under the dash there is a trailer tow reverse light relay. If you can find this, you may be able to use part of it to trigger the camera.
