      This new harness provides a splice-free installation of the MSD 6-mod controller to factory equipped EFI vehicles making installation a snap. All of the connectors plug directly to the factory units so there is no cutting or splicing of your factory wires. The compact tach adapters ensure that the ECU and the 6-Mod receive the correct signals required to keep both systems operating as designed. Once installed, the 6-Mod allows users to advance or retard the factory's timing curve, program a step retard for use with nitrous systems or even map out a timing curve through a laptop by using MSD's pro-data software.

      Product Features:

      • Provides Splice Free Installation
      • Connectors Plug Directly To The Factory Units
      • For Digital 7 Ignition Controller
