designed to simplify powering the installation of your
system in a compact package that is rugged and reliable.

make for an easy and quick installation.
The PDM’s diagnostic LEDs will provide an alert if a
short is detected.
Mounting
The PDM’s compact and sealed design can be mounted under the hood in a
location not exposed to direct heat sources, such as the exhaust system.
Use the supplied mounting hardware to secure the PDM into place.

The PDM provides Power, Ground, and Switched Connections for many
components within a system on a vehicle such as the Throttle Body, Fuel
pump, Ignition module, and Fan (Optional).

locations along with the LED functions.

recommended for cars that sit for longer periods of time before being driven, to use a trickle
charger while sitting.
