Aftermarket Wiring Harnesses and Solutions

HARNTECH designs and manufactures ready to fit assembly kits to decrease installation time and ensure a quality product is fitted repeatedly.

Most aftermarket systems requires wiring harness assemblies to

interface to both OEM equipment and individual systems.

HARNTECH has successfully partnered with various body builders and manufacturers of Water and Diesel Bowsers, Service Trucks and Fire Trucks to seamlessly integrate their product to OEM equipment.

To improve safety and reduce downtime for the off highway vehicle markets we manufacture Isolation and Lockout Stations, Power Distribution Units, Boarding Light Controllers and Optional Lighting Upgrade Kits.
