Applicable truck models covered
The diagrams cover International 3200, 4100, 4200, 4300 and 4400 units, the 7300 through 7700, 8500 and 8600, plus the MXT and RXT built within the stated date range. Each figure lists cavity, circuit, wire gauge, color and terminal part numbers for accurate repair. See the manufacturer at International Trucks official website.
Who needs the International RXT wiring diagrams
Auto-electricians tracing shorts, opens and body builder circuits need these RXT wiring diagrams because they map every connector cavity, wire color and terminal number, including the WABCO hydraulic ABS and trailer socket harnesses.
Each schematic follows Navistar drafting conventions, using the circuit number identification chart and schematic symbol chart at the front so a reader can trace a wire from fuse to load across several sheets. The power distribution chapter maps battery feeds, accessory power and every chassis and instrument panel ground, while later chapters detail the horn, heated and power mirrors, the wiper motor and body builder lighting circuits. Connector composite pages close the book with cavity-by-cavity tables listing circuit, wire gauge, color and terminal part number, exactly what a technician needs when repinning a damaged connector or adding an authorized accessory circuit.
