Plug the ATC Power Pigtail connector into the Control Unit marked "Power
Connection."

Test the trim tabs using the Manual Control. Make sure the trim tabs are

Rocker Control and Racing Control operate the port trim tab and vice versa.)

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."
