The third light is connected to the positive wire factory reverse light circuit and even grounded. When reverse gear is selected, all three lights.
Extra switch is powered from the light´s circuit and is connected directly to the circuit of reverse lights. When I turn on it, all three lights lit.
For me it works only when the parking or headlights lit. But it can be connected to the brake light switch circuit

Backfeeding a circuit like that is very bad.

As is overloading factory wiring. Powering a 55W directly from stock reverse light wire is not wise. Use the stock wire to trigger a relay that draws power from battery is better, or use a few watt LED directly, not a 55W halogen off the tiny stock reverse circuit! It will surely work, but for how long and for how much potential damage down the road? A pair of these is adding 9 amps draw to the circuit. Reckless is right.

Besides that, all the rear lights have a fuse that will blow before the wiring running to them ever reaches a point where the wiring could catch on fire, thus the fuse is there to prevent such a thing. So if the fuse blows, then that answers your question.....that you then need to run a separate wire from the front and use a relay. No need to over think this, or act like the sky is gonna fall if you tap into the existing wiring.
So tap away.

So "if" tapping into the rear tail lights was such a high risk of causing fire like some are trying to lead you to believe....do you think Mopar would be selling a JK trailer wire harness that does exactly that?
