Connect the green wire from the actuator to the right turn signal / brake light circuit on the trailer. Connect the white wire from the actuator to the negative terminal ( - ) on the trailer battery and to both a ground connection on the trailer and to the ground wire in the wiring harness from the tow vehicle. The unit will not operate properly without a direct connection to the ground circuit on the towing vehicle. Grounding between the trailer ball and coupler without a direct connection to the towing vehicle ground circuit will result in system errors. Connect the black wire from the actuator to the positive terminal ( + ) on the trailer battery and to one side of the emergency breakaway switch. Connect the blue wire from the actuator to the positive side of the trailer brakes and to the remaining unused emergency breakaway switch terminal.

G. Installation Check Procedures:
Checks With Tow Vehicle Engine NOT RUNNING, Park Brake SET, In-Cab Controller Unplugged-
Turn on the tow vehicle running light switch. Verify that the trailer running lights are ON, and that power is being supplied to the BROWN wire on the CARLISLE actuator. Make any necessary repairs.
Apply and release the tow vehicle brake pedal several times. Each time the pedal is pressed the brake lights on both the tow vehicle and trailer should be illuminated, and power should be supplied to both the yellow and green wires on the actuator. Make any necessary repairs.
Turn OFF the tow vehicle tail / running light switch. Activate the breakaway system by pulling out the breakaway switch plunger. Verify that power is being supplied to the blue wire on the actuator, and that the trailer brakes are functioning correctly. Replace the plunger on the emergency breakaway switch.
In-Cab Controller Operation - 1. With the tail/running light switch OFF, plug the in-cab controller cord into the cigarette lighter receptacle (not an accessory power receptacle). A “beeping” sound should be heard, and the in-cab controller should display a rapidly flashing yellow light. Turn on the light switch – the sound and flashing light should stop. If it continues to sound and flash, recheck for 12 volts to the BROWN wire, and/or for correct GROUND circuit wiring.
