Replacement Connector

This replacement wiring harness is engineered for Peterbilt 359 models from 1970 and compatible applications requiring Type D electrical configurations. The harness assembly provides reliable electrical connectivity for trailer systems and is constructed to meet the demanding requirements of heavy-duty truck operations. The 14-foot long 7-wire cable design accommodates standard trailer coupling connections and supports multiple electrical circuits simultaneously. This component is essential for maintaining proper trailer lighting, braking signal transmission, and power distribution between tractor and trailer units. The harness comes equipped with a complete 7-way connector system for secure and efficient installation. Designed as a direct replacement for original equipment, this harness ensures compatibility with existing Peterbilt 359 electrical systems and integrates seamlessly with factory-installed components. The construction materials and specifications are engineered to withstand the vibration, temperature fluctuations, and demanding operational conditions typical of long-haul trucking and commercial transportation applications. Ideal for fleet maintenance departments, independent truck repair facilities, and Peterbilt owners performing restoration or electrical system upgrades. This harness supports critical safety functions including trailer brake indication and marker light circuits. Proper installation of this replacement component helps maintain DOT compliance and ensures reliable nighttime visibility and brake communication between tractor and trailer units. Suitable for both restoration projects and ongoing maintenance applications where original electrical harnesses require replacement due to age, damage, or wear.
