Engine Harness

               •  Additional accessory load up to 40 amps can be accommodated with an optional accessory harness/relay kit.
            Applications
               •  Both MPI and carbureted engines received the new 14‑pin wiring harness.
               •  A new circuit breaker was introduced on the new engine wiring harness.
               •  The slave starter solenoid currently on carbureted engines has been replaced by a slave starter relay.
               •  Adapters for use with repower are available. If the adapters are used, SmartCraft would be handled by the traditional CAN
                  line (adapters are not for DTS).

                  NOTE: When installing the key switch, verify that the drain hole in the barrel of the key switch is positioned downward for
                  proper drainage.
               •  For non‑DTS applications: For dual helm installation, a key switch is used at the upper and lower station. The key
                  switches must operate independently.
               •  For DTS applications: For dual helm installation, a start and stop switch is used at the upper station. The lower station
                  can use either a key switch at the helm, or a key switch at the main panel and a start and stop switch at the lower helm.
                  IMPORTANT: For dual helm installation, both key switches used must be modified to operate independently.
