The Power Distribution Module (PDM) is a perfect accessory that removes the manual process of connecting all your electrical wires and moving them into a module for an easier electrical installation. Simply slide the stripped wire ends under the correct spot and adjust the set screw. You have the option to also have it distribute power to your Holley EFI fuel pump and a single fan (2nd fan can be connected, refer to installation instructions). The option of adding two additional 2 amp circuits for powering low current accessories like gauges, trigger relays, etc. is also provided. On the lid of the PDM is an easy to read diagram of where to connect the wires for your inputs and outputs. Mount the PDM for an impressive polished look and you're all set.
