Can P (Can 1) Connections; General Repower Information - Mercury MerCruiser Service Manual

Installation
The use of both relay kits will result in a maximum of 80 amps of key controlled power at the helm. This multiplies out on dual
engine and dual helm applications as long as the power wires to the helm are adequate to carry the total current demand.

CAN P (CAN 1) Connections

CAN P (CAN 1) data bus—Connection with a terminator resistor in place:
• The CAN P (CAN 1) data bus is terminated at each engine. Terminator resistors must be removed from the helm harness
or junction box and a jumper harness must be installed at the helm to connect the port and starboard CAN P (CAN 1) lines
together.
• If the boat is dual engine and dual helm, the terminator resistor at the lower helm is removed from the connector. The 2‑pin
link harness is installed at the upper station.

General Repower Information

• A 6‑pin fuel paddle boat harness is required.
