I think "long and hard" about trying this. There's a heck of a lot more than "camera power and backup lights" that are affected. You also have the issues with anti-sway and anti-skid systems that are disabled when the truck is in reverse. Depending on where the computer systems obtains the transmission status, you could be disabling all (or many/most) of your electronic safety systems. It could go as far (if I remember correctly) that the air bag systems are disabled when the truck is in reverse. So putting power "on the reverse power wire" may backfeed to the computer and cause all sorts of "disconnects of vital systems".
So, don't go "tapping into the 7 pin umbilical" without doing your "due diligence" or you might wind up with a truck that won't go into tow/haul, won't shift out of the lower few gears, won't protect you from a skid or a side impact and won't stop "dinging the bells" because the trailer is too close behind the truck..... On my truck, the "center stack screen" is the rear camera screen (when in reverse) and all other "center stack functions" are disabled. Clipping that wire might mean that when you turn on the upfitter switch, you can't adjust the heat/AC or turn up the volume on the radio either....
On some 2021 trucks, with the upgraded towing options, the trailer rear camera is routed to the center screen, on others it's routed to half of the mirror rear view mirror. Depending on the options on YOUR truck, you might wind up with a disabled or partially disabled "in cab system" while powering an aftermarket camera on a system that will shut down to protect itself because of the self monitoring systems.... Computers are "funny that way"....
