This Is What We Build

Aircraft

Aerospace-grade wiring harnesses for experimental and home-built aircraft.

Everything is built by an IPC/WHMA-A-620 certified technician to the same Class-3 Space Addendum standards used in launch systems and orbital vehicles. 

Auto

Whether you’re wiring a hot rod or custom off-road vehicle, your harness should be built with safety and reliability at the forefront.

Labeled, tested Class 3–compliant harnesses that simplify your build. Crafted using GPT/TXL wire and OEM-grade tooling.

Marine

Our marine products are salt proof, sealed, and 100% reliable. Don’t trust your lights and bilge pump to an overseas supplier.

Panels and harnesses that are built with tinned copper wire, Deutsch or WeatherPack connectors, and IPC/WHMA-A-620 Class 3 workmanship.

E-Bike

EV wiring must handle torque, vibration, and heat without failure. 

Our E-bike and E-moto harnesses are built with Tefzel or GXL wire, sealed connectors, and IPC/WHMA-A-620 workmanship proven in aerospace.
