Application specific instructions
How you wire the ignition will depend on the number of engines and actuators.
See table 5.

Connect the ignition-sensing wire to the
engine ignition.

The ignition-sensing wires must be connected in
such a way that an ignition-on signal is received
when either of the engine ignition switches are
on. Some boats may be wired to deliver such an
ignition signal, but you may require a Dual Ignition
Kit (HA1201) to combine the ignition from a pair
of engines into a single source. See figure 19.
