Installing the Wiring Harness and Light

  1. Run the wiring harness along the frame rail away from any moving or hot parts and connect the ground lead to the battery terminal. Use the supplied cable ties to secure the harness.

  4. Pull the indicator leads through the freshly drilled hole.
  5. Install the leads on the indicator light. It does not matter what side the leads are connected to on the light.
