Inertia Wiring & Power delivers complete electrical for your build: wiring harnesses and component systems designed as a whole and ready to install. There are two paths.

Custom — We start with an in-depth interview about your build and how you’ll use it, then design the schematics, build the harnesses, and spec the component system to match. You get a complete electrical system engineered around your van.

Standardized — Standardized harnesses are pre-designed for builds that follow a standard layout. They’re faster to deliver because the design work is already done.

Every system is built with margin. Wire is oversized for reliability and safety, and we run spare circuits for accessories you haven’t added yet, because pulling apart a finished interior to fish one more wire is the kind of mistake you only make once. That judgment comes from years of running electrical on high-end van builds.
