Custom wire harnesses · Prototype to short run
Upload a drawing. Get a quote. Get your harness.
Most harness shops take days to return a quote and weeks to return parts. HarnessMax is built the other way around: send us the drawing and get moving the same day.
No account required · PDF or photo · Your drawing stays confidential
Standard
10 business days
The default for most prototype builds.
Expedite

Subject to connector and wire availability.
How it works
Three steps, and none of them is a sales call.
- 01
Upload your drawing
A PDF harness drawing, a marked-up print, or a photo of the sketch on your bench. No account, no sales call, no NDA round-trip before you can even get a number.
- 02
Get a quote
We read the drawing, price the wire, connectors, terminals, and build labor, and send the number back with the assumptions we made — so you can see exactly what we read.
- 03
Approve and we build
Approve the quote and it goes to the bench. You get tracking when it ships. Reorders are one click, at the same price.

Your drawings stay yours
We treat an uploaded drawing the way you would want yours treated.
Uploads are encrypted in transit and at rest, stored in a private bucket that is never publicly readable, and visible only to HarnessMax staff who are quoting or building your job. We do not share them, and we delete them on request.
