I watched a few youtube videos that said if you buy the bed lights and switch the wiring will be there well it isn’t under mine (22 2500 bighorn) and i found out when i looked for it. I seen in some other forums that for a half ton you can replace the wiring harness (jumper wiring ) but i can’t find it for a 3/4 ton and was hoping someone had done this and might be able to steer me in the right direction.
