I invented the system and it is totally independent from the factory set up. It fits the Viking, gen1 wolverine, X2, and X4. The kit comes with a plug and play harness that connects to your factory harness and zip ties to secure the harness. A LED lit waterproof switch that plugs to supplied harness. An electromagnet actuator pre installed to its custom built bracket. The necessary hardware for attachment and in color picture by picture detailed installation instructions. With the press of the switch the electromagnet locks the brakes at all four wheels giving you the best park brake on the trail. The actuator can also be set manually. The kit is $175 shipped anywhere in the US. I hand build the kit entirely and I also test fit every kit for proper fitment and operation. If you have more questions feel free to call me my number is 1-270-246-0544. I have kits built, tested, and ready to ship. I also have a installation video as well. Thanks for the interest in my product. You will love a Mello FAB 4-wheel park brake on your machine!
