Step 5: Connecting the Trim Tab Wire Harness to the ATC Control Unit
Cut the terminals off the ends of the
•
existing 4-color Trim Tab Wire Harness.
Strip approximately 3/16ths of an inch on
•
each wire.
Crimp the butt splices on the Pigtail for Wire
•
Harness (PT109) onto the Trim Tab Wire Harness, matching color to color.
Plug the Pigtail for Wire Harness (PT109) into the Control Unit connection
•
marked “Relay Module.”
Step 6: Mounting the Relay Module
The Relay Module is best located in a dry
•
location close to the Hydraulic Power Unit.
Disconnect your Trim Tab Wire Harness from
•
your Hydraulic Power Unit.
Plug the Hydraulic Power Unit Harness into the
•
Relay Module Pigtail Connector.
Plug the Trim Tab Wire Harness
•
(already attached to the Control Unit in
Step 5 above)
into the remaining Pigtail Connector coming out of the Relay
Module.
Attach the black wire of the Relay Module Power Connectors to ground (or
•
to the ground stud on the back of the HPU motor) and the orange wire with the
in-line 20 amp fuse to a 12 volt positive source.
Step 7: System Check
Plug the ATC Power Pigtail connector into the Control Unit marked “Power
•
Connection.”
Turn the boat power back on.
•
Test the trim tabs using the Manual Control. Make sure the trim tabs are
•
working correctly. If not, check the connections on the Control Unit, the Manual
Control and the Relay Module. (Remember, the right hand buttons on the
Rocker Control and Racing Control operate the port trim tab and vice versa.)
The ON/OFF ATC Keypad button will not activate the ATC system until the ini-
•
tial Zero Point is set. If you turn on the ATC at this point, the blue Zero Set LED
light will flash. Refer to section 3, “Using the Auto Tab Control for the first time.”
