For each trim tab actuator:
Install a 20A fuse or circuit breaker within 7" (200 mm where ISO applies) of
the power source as required by ABYC standards. Use minimum 14AWG wire
(12AWG is preferred).
Connect the red wire of the power harness to the fuse/breaker and the black
wire to the battery negative terminal or negative bus.
Plug the power harness into the actuator harness until the locking tab engages.
Properly secure and strain-relieve the harnesses.

No power source aft
If there is no DC power source of suitable capacity in the stern you will need to create
one. We recommend you use an insulated stud terminal connector (such as Blue Sea
PowerPost or similar) for this purpose. One possibility is illustrated in figure
described below.
For each trim tab actuator:
Install an insulated stud connector within reach of the actuator power harness.
Install a 20A fuse or circuit breaker within 7" (200 mm where ISO applies) of
an available power source as required by ABYC standards. Use wire size shown
in table 5-3.
