I installed a hoppy wiring kit for my jeep that connected to the factory tailights, ect... few weeks later I was towing my boat at night and noticed that when I turn on my blinker the blinker on the trailer alternates with the blinker on the car when I am using the brakes. when the brake lights are ont on, the lights come on together. this seems strange and I was wondering if this is normal, or if i did something wrong when I installed it.
