With all Yamaha wiring harnesses, rigging your boat is virtually "plug and play." Installation and service is a breeze. All connections are color-coded and like-sized so they fit together, work together. And all Yamaha wiring harness connections are either rubber-coated or o-ring sealed for maximum corrosion protection. These are the harnesses made to order for your Yamaha power system; there's no need to splice, or guess at proper connections. They are designed by Yamaha, for Yamaha, and are a key component of the Yamaha PowerMatched™ System.
