What counts as a "requirement"

Any format works — we work with what you have

You don't need a finished drawing to start. Teams have quoted with us from all of the following:

Technical drawing

PDF or image with wire lengths, colors, terminals and connector types. The fastest path to an accurate quote.

Part number or datasheet

Give us a reference part number and we cross-reference connector series, pin count and termination style.

Sample or clear photos

Ship an existing harness or send photos from several angles — we extract the specification and confirm it with you.

Written description

"Two conductors, 30 cm, one end terminals, other end a 2-pin white plug, powers an LED module" — that level of detail is enough to start.

Schematic / pin map

Board-to-board or device wiring diagrams help us verify pinout correspondence before production.

A rough idea

Describe your application and constraints. We'll ask targeted questions and put the specification together with you.

Every parameter is yours

What we customize on each harness order

Length & cut tolerance

Cut and terminated to your dimensions, per drawing.

Wire gauge & conductor

Copper conductor selected to suit your current load and flex requirements.

Terminals

One end, both ends, or bare wire — your call.

Connectors

Your connector type, brand series and pin configuration.

Construction

Single wires, terminal wires, connector assemblies or complete branched harnesses.

Finish

Material, color, shielding, jacket type and labeling per requirement.

How an order runs

Four steps, one point of contact

Send requirement

Drawing, sample, part number or description — we acknowledge and review.

Specification confirmation

We confirm wire, terminal, connector and length with you, and quote with lead time and MOQ stated.

Production with in-process inspection

Assemblies built on our line; continuity and visual checks during production.

Final check & shipment

Final electrical and visual inspection, packed and shipped per your instruction.

Electrical check

Continuity and miswire verification on finished assemblies before packing.

Visual & dimensional inspection

Crimp appearance, connector seating, length and labeling against the confirmed specification.

In-process inspection

Checks during production, not only at the end — issues caught before a whole batch repeats them.

Documentation

Certification and compliance information available upon request — see Certifications.

FAQ

Buyer questions about custom harnesses

What do I need to send to get a quote?

A drawing, a part number, a sample, a clear photo or a written specification works. The more detail you share, the more accurate the quote.

Do you have a minimum order quantity?

MOQ depends on the product specification. We confirm the minimum quantity when reviewing your requirement.

What is the lead time?

Lead time is subject to specification, quantity and current production schedule. We confirm lead time with every quotation.

Can you match an existing harness I already buy?

Send the existing harness or clear photos with measurements. We cross-reference connector series and termination style and confirm what matches and what deviates — before you commit.

What materials can you work with?

Wire material, conductor, insulation and jacket are selected according to your specification — including PVC, silicone and other standard insulation types.

Do you provide samples?

Sample availability depends on the specification. Discuss sample options when you send your drawing or part number.

Who is behind the factory?

HSC Connectors is the export brand of Shandong Heshicheng Trading Co., Ltd., operating from our production base in Tai'an, Shandong. See About.
