Our Services
Custom Circuitry builds aerospace-grade wiring harnesses for experimental and homebuilt 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.
✔Precision-built for airframe routing
✔No guesswork: every termination is labeled
✔Designed for real-world vibration, heat, and inspection readiness
Whether you’re wiring a hot rod, airboat, or custom off-road vehicle, your harness should be built like aerospace — not an afterthought.
Custom Circuitry builds labeled, tested, Class 3–compliant harnesses that simplify your build and outperform every kit on the market. Built using automotive GPT/TXL wire and OEM-grade tooling.
✔Cleaner than any box-store “universal kit”
✔Built to spec, not cobbled together
✔Labeling + documentation = fast, safe install
Marine wiring must be saltproof, sealed, and 100% reliable. Don’t trust your lights and bilge pump to an overseas supplier.
Custom Circuitry’s marine panels and harnesses are built with UL1426 tinned copper wire, Deutsch or WeatherPack connectors, and IPC/WHMA-A-620 Class 3 workmanship.
✔Built to withstand water, vibration, and salt
✔Labeled and ready to route — no guesswork
✔Real hardware, not Amazon-grade wiring
EV wiring must handle torque, vibration, and heat — without failure. Don’t risk your build to spliced cables and questionable diagrams.
Custom Circuitry’s EV and emoto harnesses are built with Tefzel or GXL wire, sealed connectors, and IPC/WHMA-A-620 workmanship proven in aerospace.
✔ Built to handle high current and harsh conditions
✔ Plug-and-play for Onyx, Sur-Ron, Talaria, and more
✔ No guesswork, no soldering — just ride
