Install Instructions

  1. These instructions expect you to be wiring the module in at the motor for step cover because your coach has a single interface that operates more than just the step cover. If you have a a single switch on your dash that operates the step cover you should use the switch install instructions here.The kit comes with spades and butt connectors to assist in the install. You most likely will not use all of the provided connectors.
  2. Locate the step cover motor. You may need to position the step cover up so that you can access the motor below it.
  3. You will need 12v power and ground to operate the module. You can utilize a chassis ground but will most likely need to run a 12v lead from the fuse box.Attach the ground to the black wire on the module and the 12v wire to the red wire on the module.We recommend simply twisting wires together in the next few steps and testing function before you utilize any butt connectors.
  4. Select a wire going to the motor and cut it. Leave yourself 3+ inches on the motor side as a good rule of thumb.
  5. Attach a single blue wire from the module to the wire you just cut going to the motor.
  6. Attach a single orange wire from the module to the switch side of the wire you just cut.
  7. Repeat the previous 3 steps again for the remaining wire going to the motor.
  8. Before finalizing your connections and reassembling everything, you need to test it to verify that it all works properly. If the cover goes down when it should go up or up when it should go down, simply swap the orange wires with each other and it will change the direction.Once everything is working correctly, use the butt connectors to secure your connections.
  9. If you used the butt connectors, tape them and their connections from both ends of the module. Mount the module in a way that it is not hanging from the connections. It may be necessary to use a zip tie to hold it in place. The module is shock and weather resistant, the only concern is your connections being pulled loose.
