Trailer lights wiring

2017 Prius 4. Is there an easy way to wire a trailer hitch for this car? I purchased this cool rear light accessory and would like to wire it in with as little hassle as possible. I was hoping there was an easier way to wire it in than to splice many wires.

I have not tried it yet, so I do not know how good it is.
