Mission accomplished.
I went ahead and made a hole in the existing cover on the back (it was quite nicely sealed against the trailer) and routed the cable in that way.
I remembered to turn the headlights to parking/on this time too.
Of course, I got it mounted a little crooked.
But in the end, it's doing the job that I need it to do.
The Haloview camera along with the new towing features of the 2022 Toyota Tundra will make for a safe experience.
BIG CONGRATULATIONS!!! You are going to love it.
By your screen name, are you an EMT?
