Questions

Custom harness FAQ

What buyers ask before sending a drawing

01Can you build harnesses from our drawings?

Yes. Send a drawing, a BOM or a sample harness. We confirm wire gauge, colours, lengths, terminals and housings with you before quoting.

02Can I send a sample instead of a drawing?

Yes. Send the sample harness and we will prepare a drawing for your approval before quoting.

03Can you match the connectors in our current harness?

Send the part numbers or a photo of the connectors. We make 2.5 mm and 2.54 mm housings, headers and IDC connectors and will tell you which of ours fit your layout.

04What are the minimum order quantity and lead time?

Both depend on the harness and on whether new tooling is needed. We confirm them in the quotation, and samples come first.

05How do you check harness quality?

Crimped samples are pull-force tested at set-up and during production, and finished harnesses are checked against your drawing for wire order and terminal seating before packing.

Have a harness in mind?

Send a drawing, a photo of your current harness or a list of connector part numbers. We will review it and come back with a quote.
