Made in the USA, or else
Design online or upload a drawing. We build engineer-reviewed harnesses and cable assemblies with no minimum order, shipped from Kingston, NY with rush builds in as little as 10 business days.
Used by Industry Leaders
We Build Custom Wire Harnesses
Bring a finished design, a drawing, or nothing at all. Configure online for instant pricing, upload for an engineer-reviewed quote, or have us design or reverse engineer first. We build it either way.
Production and prototype harness builds from your design. Design it in the online configurator for instant pricing, or upload your drawing and an engineer quotes it.
Design a new harness from requirements, schematic to build-ready package. Then we build it.
Rebuild documentation and BOMs for legacy or undocumented harnesses, then build new units to the recovered spec.

Each connector housing. Count both ends of a mated pair separately.
Each individual conductor. A multiconductor cable counts as one wire per conductor inside it, not one for the whole cable.
Each point where two or more wires are joined or branch off.
Each continuous run of sleeving, heatshrink, conduit, or loom.
Rough preliminary estimate
$1,323–$1,789
Rough preliminary estimate only, not a quote. Final pricing depends on full requirements.

We're not a faceless corporation or overseas operation. We're real people in a real place, crafting quality wire harnesses in a historic firehouse in Kingston, New York.

We're based in Kingston's legendary Rondout, once the third-largest port on the Hudson River and a crucial gateway that moved coal from Pennsylvania to New York City via the Delaware & Hudson Canal. This thriving 19th-century maritime district shaped the entire Hudson Valley's industrial legacy.
Our workshop is housed in the historic Union Hose Company building at 218 E Union St, continuing the neighborhood's tradition of American craftsmanship and innovation.
