Here is our heavy duty replacement wiring system for the D19 Tractors. 1 gauge heavier circuitry used throughout the system rids the system of voltage drop. Heavy wiring all the way out to the Delco Generator. B&B Weathertite connectors to the Voltage Regulator are part of the HD wiring system as well!  HD Delphi 56 female connectors on the Ignition switch side.
 
This kit available with our optional high amp Ignition switch for a bullet proof system!  Eliminates wire stacking on the rear of the OEM switch when extra circuitry is needed.
