Peterson Announces NEW Corrosion Resistant Modular Harness System

New Products | 09.12.21 | pzilliox

GRANDVIEW, MO (September 12, 2021) –– Peterson Manufacturing, world-leading innovator in the engineering and production of a complete line of vehicle safety lighting and custom wiring harnesses, is pleased to announce its newest weapon in the fight against corrosion in wiring harness and lighting systems – PetersonPATRIOT™ Modular Harness System. With PetersonPATRIOT, fleets can protect their wiring harness and lights from corrosion, reduce maintenance costs, and trailer downtime.

Corrosion is the number one reason fleets replace harness and lighting systems, and lights are one of the top three CSA violations. PetersonPATRIOT was designed to provide a very strong defense against moisture intrusion and corrosion with a modular layout making it the best solution for the many fleets who fall into one or more of the categories below:

  • Fleets that want advanced corrosion protection and a flexible, modular solution
  • Fleets that turn their trailers over every 5-7 years
  • Fleets with standard configurations or limited add-on electrical accessories

Boasting a five-year warranty against defects and corrosion, the PetersonPATRIOT is a modular harness system with a distribution module that connects all the lighting components to a small footprint central hub to provide excellent corrosion resistance, easy installation, and efficient troubleshooting and repair.

PetersonPATRIOT’s distribution module is the key component of the new design. It uses a circuit board as the junction box which keeps it flexible, compact, and fully protected from moisture intrusion. The compact size also provides manufacturers and fleets maximum flexibility when choosing a mounting location.

Each harness component has industry proven amp-style connectors to stop moisture with silicon seals and built-in locking clips. The connectors are color coded by function, with keyed, one-way connectors which guarantee fast, fool-proof assembly. If a repair is ever needed, PetersonPATRIOT’s modular design allows you to quickly troubleshoot and replace a damaged cable without disturbing the entire system.

Additional components of the PetersonPATRIOT use its proven Maxi-Seal® technology with over-molded amp-style connectors to keep moisture out, our Integrated Moisture Barrier to stop moisture from wicking throughout the entire system when a wire is damaged, our easy to assemble J560 connector, our improved bullet connectors with molded in O-rings and detents offering secondary locking and improved sealing, and our ring terminals with adhesive-filled heat-shrink connectors.
