For EV conversions and gasoline builds.
Built to your exact lengths.
Wiring · Made to length
Made to your agreed component positions and cable lengths.
Order in four stepsFormosa EV makes custom low-voltage harnesses and high-voltage cables to length for each build, to your schematic or requirements, or as OEM reproductions. No minimum order.
Plug-and-play low-voltage harnesses.
High-voltage cables made to length.
Low-voltage harnesses and high-voltage cables
Custom to your schematic or requirements, or an OEM reproduction.
One harness is enough. One-offs and low-volume runs are built to the same standard; design consultation is available on request.
Every low-voltage harness is checked circuit by circuit. Every high-voltage cable is hipot tested, and fine connector pins get microscope inspection.
Automotive-grade or mil-spec connector and wire options for OEM and aftermarket components. Wiring diagrams and schematics are not supplied.
Low-voltage harnesses and high-voltage cables from one supplier, made to your agreed measurements.
Each harness is specified for the components and cable routing in your build.
Supplied parts
Low-voltage harnesses and high-voltage cables.
Applications
