Built by problem-solvers, for problem-solvers.
Founded in 2024, M.A.D. Wiring helps builders, manufacturers, and innovators get their projects moving with custom wire harnesses and cable assemblies.
We specialize in automotive, marine, specialty vehicle, and one-off applications—especially the projects that don't have an off-the-shelf solution. Need a prototype fast? Working on a custom build? Developing something that's never been built before? That's where we do our best work.
Our goal is simple: deliver high-quality, dependable wiring solutions with the speed, communication, and attention to detail our customers deserve.
