I have plow prep package, under the seat was the plow upfitter package(8466970) listed in bulletin 147, as well as the wire harness (84732643) in 161 . I'm not sure if the dealer just didn't get the switches or I need to order it, is there anything else I need? does the switch just plug in somewhere under the dash? seems like the power listed in bulletin 153 is the same as the plow upfitter package? You'd think if your truck has plow prep package, the switch would be part of it automatically
