Hey Salman, so since your Jeep does not have a traditional stop light switch circuit, you'd need to use the RoadMaster Stop Light Switch Kit # RM77RR.
If you didn't want to use that, then you could also use a wireless brake controller like the Curt Echo # C51180 which just gets installed in your 7-way.
