X1 Wiring Harness
X1 Primary Wire Connections
The primary wires on the X1 wiring harness connect to the appropriate devices on the vessel to allow for digital
control or monitoring. When connecting a device or devices to a wire on this harness, you must use the wire
gauge specified in the table at the very minimum. For long wire runs, you should consider using larger-diameter
(smaller gauge number) wire to minimize power loss.
NOTE: You should refer to ABYC or your local and regional standards when determining the maximum length
and gauge of wire extensions.
