    MSD Ignition 7789 - MSD Power Grid Ignition System Details


    The Harness, PN 121-7789, allows a user to use their existing Programmable-7 Harness to install the Power Grid System with minimal changes. The harness is designed to be a direct plug-in for all existing wires, but will need two new wires run if the user desires the two new inputs of the Power Grid.

    The MSD Power Grid Ignition System is an upgraded version of the Programmable 7-Series Ignitions and consists of a central controller and an ignition that is compatible with all MSD boxes, but is specifically designed for use on the Power Grid-7 box. The controller is the brains of the system and is designed to mount on top of the Ignition housing. The ignition is a high output CD ignition that incorporates CAN-Bus technology that reduces wiring and simplifies accessory module additions. The Power Grid Controller includes View Software, wiring harness, micro-SD card and mounting hardware. The ignition (sold separately) includes a harness and mounting hardware.
