I can't help you out with grill pictures for Blue Ox (I use Roadmaster), but I can help you out with the tail light kit.
The little silver tongue below the license plate frame (under the "t" in Portland) is the socket for my tail lights (these pics are in my Garage):
See the black bracket (to the right of the 4 diodes) in this next pic? Regardless of what brand of tail light kit that you buy, if you install the socket in the grill you need to put a bracket on the inside of the grill behind the socket - to anchor the socket. Otherwise, plugging and unplugging the socket will weaken the plastic around it. Spare brackets can be ordered from Roadmaster - because I ordered one. It cost about $14 USD (that includes shipping). If you're good with metal fab, you can make one yourself.
Camping World removed the skid plates and then ran (strung) my tail light wiring right across the bottom of the car and it comes up through the floor behind the passenger seat and into the right-rear quarter panel - with the rest of the car's wiring.
Here's the trick:
DO NOT run the tail light wires from the right quarter panel through the engine bay to the left quarter panel. Camping World did that and it cooked the wires. Run the wires INSIDE the car from the right quarter panel to behind the weatherstripping at the bottom of the tailgate then over to the left quarter panel. The wires won't get hot enough to melt and they're tucked out of the way, out of sight.
In this pic you can see the socket screwed to the bracket in the lower grill (it is below the license plate). You'll also see a length of flex tubing used to cover the wiring for about 2 to 3 feet - to protect it from exposure, untl it's well protected within the skid plate.
