This change was called a Mid Cycle Enhancement. This document will be updated only to reflect a major subsystem change until the next platform major electrical redesign. This document is believed to be correct until the next platform major design change. This document is organized as follows:  \n• Systems Operation – How it works  \n• Component Locator – Where it is  \n• Connectors & Pinouts – What it looks like, and finally,  \n• Subsystem Schematics – Detailed wiring and electrical schematic information.  \nWHAT’S NEW FOR THE LIGHT DUTY C/K FULL SIZE TRUCKS MANUAL  \n• Detailed System Operation Instructions are provided for PTO and Fast Idle operation. Also included is information on Trailer Wiring, Exterior Lighting and the Passlock interface. This section has been expanded to have diagrams integral to the text rather than reference a separate section for graphics.  \n• Component Locator Pages have been included to show the location of major electronic modules on both the Pickup / Cabchassis and the Utility vehicle.  \n• An Acronym an Abbreviation list used in the Electrical Component Legend, Ground Zone, and Electrical Schematic sections is included.  \n• Connector Detail and Location Illustrations are provided for many interfaces. Terminal, Cable Seal, and mating connector information have been added where appropriate.  \n• Detailed Electrical Schematics are provided for most subsystems.  \n• New LLY 6.6L engine information is added for diesel engines sold after 1/01/04 . See LLY ECM Connector and Location Drawings, Engine Controls, and Transmission Schematics.  \n• The LLY 6.6L engine ECM is new for 2006. The connectors changed from a 3-way to a 2-way. Connector pin-outs and location are included in the connector section. Schematics for the ECM and affected subsystems are not included in this document.  \n• An expanded LED Turn Signal page is included in the Application Notes.  \nSPECIAL INTEREST TO UPFITTERS  \nMID BEC provides a convenient in-cab location for interfacing with the vehicle.  \n2003 & Beyond Light Duty C/K Full-Size Truck Electrical — REVISED 04/2006  \n(continued on next page)  \n2003 & BEYOND LIGHT DUTY C/K FULL-SIZE TRUCK ELECTRICAL   \n(Overview — continued from previous page)  \nNavigation  \nThe Table of Contents and Index items are linked to the actual page.
