    NSA Ready Brute Elite II tow package
    I have a 2020 Jeep Grand Cherokee Trailhawk and am looking for some help with a problem. Just added the NSA Ready Brute Elite II so I can tow the jeep behind my moterhome. All has gone well except for the moterhome brake light. A wire goes from the my cab to the Jeeps brake peddle brake light switch. When the peddle is pressed the light comes on. The you tube videos show a white switch with 5 wires. Mine is a dark switch MOTOKU with 3 wires. I figured one is 12v one is brake lights and one is the high third light. But that doesn't explain how the car needs the brake pressed to start. Anyone got ideas?
