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
metal butt splice and T178552 heat shrink tubing.
2. If alternator does not have a D+ terminal, locate
another source for switched power.
Use a VCU10018 metal butt splice to splice to an
existing wire or terminal.
Cover splice with T178552 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
Testing Power Harness Connections
1. Using a voltmeter measure voltages in the 4-pin
connector of VCA10002 Power Harness as
indicated in the chart below.
