International Truck and Engine Corporation reserves the right to change specifications or design without notice and without incurring any obligation S08311 3-1 Introduction Note All wiring connections between components are shown exactly as they exist in the vehicles It is important to realize, however, that no attempt has been made on the schematic to represent components and wiring as they physically appear on the vehicle For example, a 4-foot length of wire is treated no differently in a schematic from one which is only a few inches long Furthermore, to aid in understanding electrical (electronic) operation, wiring inside complicated components has been simplified Central Junction Box (CJB) (14A067) 13−4 Hot in run F2.6 5A 31 C270a 1405 LB/BK See page 13−8 11 C220a Instrument cluster (10849) 1) Traction control 12 Complete Circuit Operation Each circuit is shown completely and independently in one cell Other components which are connected to the circuit may not be shown unless they influence the circuit operation 939 15 Current Flow (1) Each cell normally starts with the component that powers the circuit, such as a fuse or the ignition switch Current flow is shown from the power source at the top of the page to ground at the bottom of the page In order to concentrate on the essential parts, power supply and ground connections are sometimes simplified by a dashed line in the schematics A full representation of the power supply of a fuse or the power distribution from a fuse to various components is given in cell 13 “Power Distribution” Full representation of the ground connections are shown in cell 10 “Grounds” Switch Positions (2) Within the schematic, all switches, sensors and relays are shown “at rest” (as if the Ignition Switch were OFF) Splices (3) A dashed line indicates that the splice is not shown completely A reference is given to the page where the splice appears in full It is also listed in the Index 939 62−3 16 VT 603 27

S200 530 LG/YE G104 Introduction Component Referencing (4) Each component on a schematic has a reference to the component location view or the page where it is shown completely It is located to the right of each component Component Names, Notes and Base Part Numbers (5) Component names are placed on the right hand side of each component Any notes that describe switch positions or operating conditions follow the name Descriptions of the internals of the component are also included here The page where the component appears in full is listed in the Index The base part number for a component is listed in parentheses next to or under a component These part numbers will appear any place the component name appears in the publication Internal Name and Function Identification Numbers (6) Some components on each page have internal symbols with an identification number located to the right You can identify the internal symbol or function by finding the corresponding number under the component name Circuit Function Identifiers (7) Some components without internal schematics use symbols or text to describe the function of a circuit in a system 3-2 3-3 Introduction Fuse and Relay Information Cell 11 “Fuse and Relay Information” contains a view of the fuse-/relay box in which all fuses and relays are identified Fuse and Relay Numbering and Naming F1.12 F1.1 F1.13 F1.2 F1.14 F1.3 F1.15 F1.4 F1.23 F1.24 Fuse and relay numbering and naming follow the indication of the fuse panel cover In addition, a prefix precedes the fuse number to facilitate finding the fuse in the Component Location Charts, e.g “F1.” precedes Power Distribution Center fuses, and “F2.” precedes Central Junction Box fuses Power Distribution S130 Battery Cell 13 “Power Distribution” shows the current feed circuit The current path is shown from the battery to the ignition switch and to all fuses It also shows the circuits protected by each fuse The circuit is traced from the fuse to the component All details (wires, splices, connectors) between the fuse and the first component are shown 57 Fusible Link A 1) 12 gauge 2) gray S131 BK F1.20 10A F1.21 20A G1002 Hot at all times Hot at

Introduction Ground Distribution Cell 10 “Grounds” contains the schematics that show the complete details for each ground connection or main ground splice This is useful in diagnosing a problem affecting several components at once (poor ground connection or ground splice) All details (wires, splices, connectors) between the ground point and the components are shown These ground connection details are shown here in order to keep the individual cell schematics as uncluttered as possible Headlamp, right (13008) 85−2 57 C1041 BK C162 57 BK Fog lamp, right front (15200) 86−1 57 Side lamp,

Introduction Component and Connector Information Cell 152 “Component Location Charts” helps the user find where the various items depicted on the schematic can physically be found on the vehicle A brief written description of the location is given, along with a reference to the component location views Cell 151 “Component Location Views” show the components and their connecting wires as they can be found on the vehicle Cell 150 “Connector Views” show the views of the pins and/or cavities of all connectors The pin and cavity sides are shown separately as if the connector were disconnected The color of the connector housing is indicated next to the connector number when available The harness causal number is located above the component name and below the connector number or above the connector face itself Wiring harness designations are listed in cell 152 “Component Location Charts” Circuit function charts are located below each connector C150 (BK) 12A581 Wheel speed sensor, left
