Heavy Duty Vehicle Wire Harness

Home / Products / Heavy Duty Vehicle Wire Harness

Trucks may travel from muddy slush or freezing cold to scorching, dusty heat in the same trip. As a result, every part of the trailer, including the electrical system, must be able to withstand the widest range of operating conditions. At KINKONG, we build custom harnesses for all types of rigs, from forklifts that load and unload ships to semi-trailers that haul cargo from one shore to another. We'll evaluate all the environmental stresses your truck is subjected to and build reliable truck harnesses to keep your equipment running wherever it goes.

Our custom braiding equipment allows us to make the toughest trailer wiring harnesses that allow the cab to control every part of the electrical system, from lights to brakes. We also develop custom potting for your wiring harness or connector to increase durability and minimize replacement costs, making the right material for each application. We will work from your drawings or work with you to develop a manufacturing process for trailer hitch harnesses that can withstand wear, water, shock, vibration, corrosion and extreme temperatures.
