Hello, I have a 2005 3500 Dually with a 5.9. A previous owner added a flatbed, and did not install the lights correctly to keep it from hyper flashing. I tend to be very good with vehicle wiring, so I planned on fixing it myself. I added resistors, dummy lights, anything you could think of. The previous installed did a hack job that I’m sure is causing my issue so I’m planning on reworking it all together however I can’t find any diagram anywhere labeling the wires in the wire loom leading to the rear taillights. Anyone have any insight?
