4 Pin, 4 Wire Power Cable (part# 10030)
This cable is similar to the Pin, 3 Wire Cable but it adds a green chassis ground wire. This power cable is only needed
for vehicles equipped with negative side battery disconnect switches (typically construction equipment).
This cable requires the vehicle to physically move at least 5 MPH for at least 100 feet to properly complete new
installation checkout. If this is not performed, GPS and discrete input data will not be present in Ground Tra ic Control
until those thresholds are met.
4 Pin Testing and Cable Management
The 4 pin power cable is used on Non-J1708/J1939 and non-OBDII installs. It is also used on J1708/J1939 installs with
switched power issues (as indicated by flashing “Status” LED with engine running). See General Guidelines and the
following requirements.
1. All power leads must be connected to the vehicles protected circuitry (for example, the fuse panel and circuit
breaker panel protected circuits). Never electrically connect Zonar equipment to unprotected circuits (for example,
directly to the battery).
2. All power leads (red and white) must be protected with a 3 to 5 amp fuse and inline fuse holder (included) for
optimal system protection.
3. Electrical fuses should be installed as close as possible to the source of power.
4. For vehicles equipped with “noise kill” switches (late model school buses) –
Do not
wire any Zonar equipment to
the “noise kill” circuitry.
Power Bundle Wiring – 4 Pin
Red – Constant DC (+8 VDC to +32 VDC), dependent on system type
Black – Battery Ground must be less than 1 ohm (measure from 4 Pin connector to chassis attachment point)
