MSD Power Grid Harness Adapter, PN 7730 to Digital-7 Programmable

The Harness, PN 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.
