The integrity of the ignition connection is critical to the safe operation
of the Optimus EPS steering system. Please note the following:
•Whenever possible, make your splice connections in dry areas of
the vessel. If you must splice in a potentially wet area, always secure
the wires in a way that keeps the splice out of pooling water.
•Use sealed, heat-shrink butt splices, such as Molex Perma-Seal,
or a soldered connection with heat-shrink tubing. Always follow the
manufacturer’s installation instructions.
•Secure the wiring on both sides of the splice so that there is no
strain on the splice connection.
•Choose a route for the wires that minimizes exposure to water,
high temperatures, and mechanical damage.
On most vessels you will have one of two options for an ignition source:
a single ignition source wire, or you will have to splice into an existing
ignition wire.
