Con

necting the ground output (GND) from the PDU

This output ground connection is the return path for the device/equipment connected to the
+12V OUT from the

PDU

1. Run the ground wire from device (i.e. light and siren controller) to the

PDU

mounting loca-

tion.

2. Prepare the wire in the same manner as the “+12V OUT” and insert the wire.

Connecting the Ignition Control to the PDU

To activate the ignition control and timed outputs feature, the

PDU

must receive a control sig-

nal from the vehicle.
1. The installer must locate the ignition output from the vehicles wiring harness and run an 18

AWG wire from this point to the ignition input (IGN IN) on the

PDU

Care must be taken to connect the correct ignition control wire from the vehicle wiring har-
ness, some of the newer vehicles have more than one type of ignition control wires.

The in-

staller must consult the factory specifications and wiring diagrams for the vehicle that is
being retrofitted with the equipment and this PDU.
