Legally a trailer only needs right and left turn signals, brake lights, and running lights. The license plate light will be tied into the running light circuit. On a trailer, the turn signals and brake lights are on the same circuit on each side. So the minimum you will need is 4-wire bonded wire such as # 16-4B-1 that you have referenced.

For a trailer side 4-Way you can use # A20WB and you would not need the wire by itself. This is a 20 foot length and the running light circuit is split, one for each side of the trailer. White is ground, brown is running lights, yellow is left turn and brake lights, and green is right turn and brake lights.

Or you can get everything you need in one kit such as # TL5RK. You will get tail lights, side markers, quick splice connectors, a license plate bracket, and a harness.

I have linked our trailer wiring help article for you.
