Here you can connect with our team of experts, keep up to date with the latest company information, and be the first to be informed of new products. Harness Master Wiring Systems (HMWS) was established in 2006 to service a niche market for electrical wiring harnesses, installation kits and lighting bars for mining, automotive, and transport applications. At Harness Master Wiring Systems we offer d

esign and development, manufacturing and, if required, installation services for all electrical wiring systems on light and heavy vehicles. We also supply all accessories including switches, lights, and beacons as well as jump start receptacles and e-stops. Harness Master Wiring Systems is a wholly owned West Australian company and our Australian plant and head office is based in Perth with sales, design, manufacturing and installation capabilities thus giving a strong local support presence for our clients. Harness Master Wiring Systems own plants in Australia and the Philippines, staffed by skilled engineers with many years of industry experience. Our local and global presence allows us to be responsive and understand your needs while remaining competitive. Instant engineering and prototyping is one of our specialities, and we can have you project ready in record time. We are happy to do large or small production runs, and to supply standardised or custom solutions as needed. While we started out making wiring harnesses, we also produce brackets, enclosures, lighting solutions and complete kits and we can produce and supply all engineering and schematic drawings when required. We are currently the specified supplier to Rio Tinto for all their on-site light and heavy vehicles. We also supply our products in quantity to BHP and Westrac.

At HMWS, we design overmolded cable assemblies built for tough environments.

Each unit is fully sealed, with the cable, connector and housing fused into one IP-rated structure.

By eliminating mechanical joins, overmolding eliminates common failure points and creates a seamless barrier against water, chemicals, vibration, and wear.

If your current setup relies on frequent maintenance or field terminations, it might be time to upgrade to a more reliable solution.

At HMWS, IP ratings aren’t just a technical detail, they’re a guide to building products that last in real-world conditions.

In industrial environments, dust, moisture, water, and debris can quickly impact performance if components aren’t properly protected, leading to more maintenance, downtime, and reduced lifespan.

That’s why our wiring systems, connectors, and assemblies are designed with the right level of ingress protection in mind, ensuring reliable performance where it matters most.

If you’re unsure what protection level you need, our team is here to help.

The M10 Feed Through Terminal Stud provides a secure and efficient power connection solution with an IP67 rated design.

Each stud is easily identified with brass components and a durable nickel plated finish, each clearly identified with red and black colouring for fast and accurate use of the positive and negative connections.

Designed with practicality in mind, the compact unit enables a smooth installation process without the need for specialised tools, helping reduce downtime while delivering long lasting reliability across a variety of applications.

Small electrical faults can quickly turn into big, costly problems.

With today’s increasingly complex vehicle systems, protecting your wiring from the start is essential. The right components can help prevent damage, reduce downtime, and keep everything running reliably.

The HMWS ISO 280 Series 6 Amp Diode is designed to do exactly that by supporting better performance and long-term system protection.

Connector corrosion causes costly equipment failures in coastal and chemical environments. Learn how material selections prevent corrosion and extend the electrical system lifespan in harsh conditions.

Treating overmolding as an afterthought is where many organisations fall short. At HMWS, it’s a core part of every project stage.

By managing overmolding in-house, we reduce supplier handoffs, streamline design-to-production, and deliver:
↳ Faster DFM cycles with real-time prototyping feedback
↳ Greater material and dimensional traceability
↳ Secure private label manufacturing
↳ Scalable production without outsourced tooling delays

The result is cleaner cable assemblies, fewer connector failure points, and a more reliable supply chain.

Quality comes standard at HMWS. Durability, efficiency and compliance are built into everything we manufacture.

To keep standards high, we carry out mid-process inspections to monitor performance and catch issues early.

The result is more consistent products, fewer defects and less rework.
It is all part of making sure our customers get reliable, high-quality products every time they work with us.

In environments where downtime, water ingress, and cable failures can halt operations instantly, every connection matters.

HMWS delivers tailored solutions built for performance through high-quality overmolded assemblies, custom metal fabrication, true plug-and-play integration and tooling, we help keep operations moving when it matters most.

Supporting the underground rock industry allows us to develop and hone our expertise to create the most efficient solutions and effective outcomes.

This is carried on after production through our aftermarket support where we assist in reordering parts, assist in servicing and fault finding, and hold stock to support maintenance activities.
