5.2.6 Beacon and Buzzer Modules
Verify the Beacon and Buzzer installation locations make
them visible and audible to individuals around the vehicle.
□ Install the Beacon and Buzzer in suitable locations.
□ Connect the Beacon with the mating connector on wiring
harness.
□ Connect the Buzzer wires (with ring terminals) routed earlier.
The red wire goes to positive on Buzzer, and black wire goes to
negative on Buzzer.
5.2.6 Display Box
□ Connect the Display Box to the 4-wire connector coming from
the control box.
□ Install the Display Box in a suitable location with provided
screws.
Mount the Display Box inside the cab or a cabinet protected
from extreme weather. The Display Box is splash-proof, but
not fully sealed. Ensure that it will not get kicked or hit by
tools and equipment.
5.3 Connecting the In-cab Wiring
□ Unplug the OEM foot pedal connector from the foot pedal
assembly.
□ Find the purple-green wire attached to pin 3 on the truck
harness. If needed, pull back any cover on the cable going into
the dash to expose the wires.
Verify with a multi-meter that the resistance between pin 3
on truck harness and truck ground is close to 0 Ohms.
□ Remove insulation on the wire and solder it to the 60” long
green-yellow “DIGITAL GROUND” wire coming from Control
Box. Trim the green-yellow wire’s length as needed before
soldering and sealing.
