Given the inevitability of ripping off the 7-pin trailer plug, I decided to do something about it. The two ways most people get around it are to make a bracket that puts the connector facing the ground, or, find a way to put it in the bumper. I went the bumper route as it looks cleaner and more OEM'ish. To the install!
First off was disassembling the Toyota 7-pin plug. I don't have many pictures of this as it was a bit of a pain, but the basic steps are.
1. Unbolt the plug and bracket from the truck.
2. There are 4 tabs around the perimeter of the plug that need to be depressed. These hold a cover on in the inside of the connector. It sucks trying to hold the cover open while fishing the cover out and making sure all of the tabs stay depressed, but, with enough manipulation you can get it pulled out.
3. Remove the O-ring behind the cover.
4. Pull the white plastic cover out. Once again, it is snapped into place and requires some work to get it out.
5. The wires will now pull out of the back and you should be left with the separated plug and the wiring harness.
Tada!

Not wanting to re-use the Toyota plug due to the weird shape, I sourced one from Amazon. It was a sealed Pollak connector. It was the right shape so I grabbed it. Feels like a quality unit.

I chose to mount it right next to the license plate. Taped up the bumper for cleanliness, marked the center of the hole, then gave it a whack with a center punch to keep the drill bit from wandering.

I drilled out the center with a bit slightly smaller than the hole saw arbor bit to make it a little bit easier to get things going. There's no going back now!

Even more now going back now. Took a 2" hole saw to the bumper and cut out a big ole' circle to fit the plug.

Test fit the plug to figure out where I needed to drill the mounting holes. Drilled all 4 and primed them up to hopefully prevent any rusting. Done! Time to mount the plug.

Like an idiot I forgot to take a picture of where the stock wires connected to the plug to figure out what color wires went to what terminals. After a bit of googling I came up with following:
White = Ground
Red - Left Turn
Brown = Right Turn
Black = 12V hot
Blue = Brakes
Yellow = Reverse Lights
Green = Tail Lights
All wired up. Things aren't all twisted up so I'd wager that it's right. Not to mention I rarely tow anything, so if it's wrong I guess I'll find out in a few years.

4 5mm button head cap screws later and it's done! Very good looking.
