Helpful Expert Reply:

The Curt Vehicle to Vehicle Tail Light Converter # C56196 that you purchased (along with some additional trailer lighting) separates the combined stop/turn signals fed to it into discrete stop and turn signals that can be fed to the individual lights. Since your toy hauler has incandescent lights on it the addition of a LED third brake light should not pose any issues related to current demand.

This vehicle-to-vehicle converter connects at the toy hauler lights at the rear of the trailer. Try to mount it in a protected location safe from moisture and road debris. You might consider using a junction box such as # 38656 to house the converter module. Note that the brown running light circuit completely bypasses this converter; only stop/turn signals are fed to the input side (which also has a white ground wire that grounds to the trailer frame). Since this converter splits the blinking turn signals out from the stop lamp signal, the stop lamp output on the red wire will not blink, but instead deliver a steady brake light signal.

The red output wire from the converter connects to your Optronics LED 3rd brake light, part # STL80RB, which also requires a ground connection to the trailer frame through its ring terminal. You will not need to connect the green or yellow turn signal output wires to your trailer unless you wish to add additional turn signal lights. If not needed the green and yellow output wires can be capped off.

I have attached a diagram showing how this unit is wired into your trailer lighting system.
