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.

Build From Your Design

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.

Wire Harness Design

Design a new harness from requirements, schematic to build-ready package. Then we build it.

  • Schematic to Routing
  • DFM Review
  • Built In-House

Reverse Engineering

Rebuild documentation and BOMs for legacy or undocumented harnesses, then build new units to the recovered spec.

  • Legacy Connector ID
  • Drawing Recreation
  • Rebuilt In-House

Instant Ballpark Estimate

For design and reverse engineering projects. Building your design? Use the configurator above for exact pricing.

10

Each connector housing. Count both ends of a mated pair separately.

50

Each individual conductor. A multiconductor cable counts as one wire per conductor inside it, not one for the whole cable.

5

Each point where two or more wires are joined or branch off.

2

Each continuous run of sleeving, heatshrink, conduit, or loom.

Rough preliminary estimate

$1,323–$1,789

PROUDLY MADE IN THE USA

Authentic American Manufacturing

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.

MiniProto's workspace at the historic Union Hose Company building in Kingston, NY

The Historic Rondout District

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.

“Why do I have to wait multiple days for a simple quote? Haven't we figured out a better way to do this by now?”
