HARNESS TESTING

We design and fabricate custom front panels, gauge and accessory panels and enclosures that combine functionality with a clean, professional look. Whether for control systems or display interfaces, we tailor every detail to your technical and aesthetic requirements.

Protect your equipment with custom-designed Pelican cases featuring foam inserts, wiring access, panel mounts, and integrated electronics. Built for durability, mobility, and convenience in demanding environments.

Every harness we build or repair can be thoroughly tested for continuity, shorts, and proper pinout using industry-standard equipment. Our testing ensures your harness is reliable and ready to perform right out of the box.

CONNECTOR POTTING
