CONNECTING B+ UNSWITCHED POWER (RED
WIRE)
CAUTION: Before doing any electrical
maintenance, turn battery disconnect switch
OFF or disconnect negative (-) battery cable.
Damage to electrical components or
personal injury could result if a power wire
is shorted to ground.
This connection supplies battery voltage to the
communications controller regardless of key switch
position.
Typical connection for unswitched power is B+ terminal
on the alternator.
If connecting B+ Red wire terminal to an existing
machine wire, use VCU10018 Connector and T178552
Heat Shrink Tubing.
CONNECTING D+ SWITCHED POWER (BROWN
WIRE)
This connection supplies switched power to the
communications controller.
Connect to a place where battery power is present
with the key switch ON and not present with the key
switch OFF.
Typical connection for switched power is D+ terminal
on the alternator.
1. Connect D+ Brown to switched power source. If
splicing into existing machine wire, use VCU10018
Connector and T178552 Heat Shrink Tubing.
2. If alternator does not have a D+ terminal, locate
another source for switched power.
Use a VCU10018 butt splice to connect to an
existing wire or terminal.
Cover splice with heat shrink tubing to prevent
shorting to ground.
CONNECTING GROUND (GND) (BLACK WIRE)
This connection provides a ground for the system.
Connect Black Ground wire to alternator case or
machine frame.
CONNECTING W+/R+ ENGINE RUNNING (PURPLE
WIRE)
This connection provides the communications
controller with a signal indicating the engine is running.
A minimum of 6 volts is required.
Typical source for this signal is the W+ or R+ terminal
on the alternator. This provides a signal when the
engine is running.
Three W+/R+ Purple wires are included in the harness,
each has a different connector. Choose the one that
fits your alternator. Tie the other Purple wires to the
harness so they won’t be damaged during normal
operation.
If Machine Has: Connect Purple Wire To:
W+ terminal on alternator W+ alternator terminal
R+ terminal on alternator R+ alternator terminal
If alternator does not have Switched power source
above terminals
