basic rundown:
buy attachment kit from Honda
buy aftermarket camera
buy about 10ft of 18-20 gauge wire
buy 09 tailgate handle in your color
buy whatever you choose to splice wires (taps, solder, plugs, etc)

then as per the instructions that honda gives you, take everything apart.
the camera basically fits right into the tailgate handle, and the tailgate
handle is a direct swap with the original, very easy. you may need to lightly
sand the inner part of the hole to get the camera to squeeze in.
the video line will run all the way to the cab, it's long enough. but you'll
have to extend the power wire for it's not very long, that's what the extra
pieces of wire is for.
once in the cab, the video and the power wire for the camera just get
spliced into the factory sub-harness that comes with the attachment kit.
so instead of making a plug and plugging it in, you're cutting a plug and
connecting/soldering some wires.
the rest is just per the oem instructions as far as where to put the wires,
where to tie them, how to take stuff apart, all that. the instructions are
quite solid.
it takes lots of time to take apart the truck and put it back together. running
the wires and connecting them takes less time in my opinion. the whole job
will take you from 3 to 8 hours probably.
