Harness Design & Schematic Software

Wiringly simplifies the process of creating complete, error-free wiring schematics. Using our interactive digital canvas, you can drop the Holley TerminatorX directly into your project, automatically load these control unit pin assignments, and connect them to your power distribution units or engine control units.

The platform tracks your wire colors, gauges, and terminal types automatically, compiling a complete bill of materials (BOM) and cutting list for your physical build.
