9. The wiring harness is fairly simple and easy to install. You need to hook a positive and negative cable to the battery, splice into two wires under the carpet (for the steps' retraction/deployment actuation), and plug the connectors together for the Powerbaord controller, the two motors, and the four LED lights.
The Powerboard controller was stuck onto the side of the fender with some double-sided sticky tape, and was the last thing we plugged into the wiring harness.
