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• The slave starter solenoid currently on carbureted engines has been replaced by a slave starter relay.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).

• 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.
