I do have a round receptacle on my truck, but isn't that a 7 wire plug?
Not necessarily; it could still be a 4 wire. I have a round 4 wire on my boat trailer

Brown wire to the tail or parking lights. Green wire to right turn signal/brake light. Yellow wire to the left turn signal/brake light. White wire to common or chassis ground.

I hooked the greens together, and the yellows together, the whites together, and the browns and the white paired with the brown together, still nothing works.

I did not have it hitched to my truck. I just backed up enough to plug it in. Wouldn't it be grounded through the plug? If thats what the problem is, then holy shite, I'm a moron... I will try on my lunch break and report back.

It should ground through the plug but the frame-hitch-ball ensures it’s properly grounded all the way to the truck battery, in case the plug wiring isn’t enough. LEDs it’s a non-issue since the current is low but with incandescent bulbs, and that they felt it necessary to run three independent grounds, you may not have thick enough ground wire for the draw. I’d be surprised but not shocked if that’s the case.

Pull new wires front to back

Did you save the old plug? Do you have a multimeter (like the $7 one I posted above)?
Use the continuity function of the multimeter to see which wire goes where on the old plug. Test each one of the 4 pins on the plug and test each wire. When it says you have connection, make a note of it. Then take your 4 wire harness and wire accordingly.
Easy peasy.

Except you missed the fact that the original plug is busted, which is why I'm in the spot that I am in. Before getting a multimeter, I'm going to put new tail lights (bulb was busted on one of them). If they don't work, then I'm going to pull new wire.

From the Manual:
Yellow Wire - Left Stop & Turn
Green Wire - Right Stop & Turn
Brown Wire - Taillights, Rear Marker Lights, Front & Rear Side Lights
White Wire - Ground
State and Federal regulations require all types of trailers to be equipped with tail, stop, turn and side marker lights.
Trailers over 80 inches wide must have clearance and identification lights. All the necessary lights are supplied by us, the
manufacturer, however it is the owner’s responsibility to maintain them in good operating condition at all times.
Make sure the ground wire is attached to both the trailer and towing vehicle to make a sure, positive ground. Some towing vehicles are equipped with a 4-wire taillight systems. It then becomes necessary to use a four to a three wire converter

Ohh trust me, I fully expect a
I checked all my fuses in my truck. I have the rewire kit, and new LED tail lights. When I get home, I'm going to install the new lights, and wire everything up as we all assume it should be wired, check my ground to the trailer, and hitch it up. Then crank the truck. Hopefully everything will turn on like nothing was ever messed up...

Then cut it open and follow the wires. Even it it's broken, you can use the meter to test continuity on the broken part of the plug. so long as there is still some metal there, it will work.
This really isn't that hard.

Yes, it is. The plug is molded around the wires. I fought with it for 20 minutes last night using cutters that weren't quite big enough, and a serrated blade knife. Barely made a dent in it.

Alright, just to give everone an update:
I replaced both tail lights with LEDs, and connected like colors of the 8 wires of the trailer to the same colors of the four wires of the new plug, and now everything works. Not sure where the issue was as the running lights up front were not coming on previously, and I did nothing to those, but those now work as well. It does not have to be hitched to work.
Each tail light has three wires. A ground, a running light wire, and a signal/brake light wire as we all assumed. Again, I don't know where the problem was, but if I had to guess, it was in a short somewhere in the ground of the plug or at the ground connection of the tail lights.
What do you think?
