At Hotham, we specialise in the deisgn and manufacture of advanced automotive & custom electrical harnessing solutions, for heavy-duty, industrial, and emerging technologies. We combine technical precision with practical experience to deliver reliable, production-ready wiring systems tailored to each project. Our expertise spans prototypes to full production builds, providing robust harnesses that meet industry standards and perform in harsh environments. With strong technical capability across automotive, mining, off-highway equipment, and machine electrification, Hotham supports OEM solutions and industry partners with dependable electrical systems and strong engineering documentation.
Electrical systems and harnessing are Hotham’s core focus, with all work built around delivering reliable, well-engineered wiring solutions. We provide installation, integration, and diagnostic support to ensure every system operates safely and to specification.
Hotham provides complementary mechanical support services to ensure our harnessing solutions integrate seamlessly with the equipment they are installed on. This includes fabrication, fitment, and minor mechanical modifications required to achieve optimal routing and reliability.
Hotham delivers end-to-end harness design solutions, including specialised reverse-engineering of OEM and legacy wiring systems.
When equipment is unsupported, discontinued, or urgently needed back in service, our team can rapidly capture the existing harness layout and convert it into modern, fully documented, and manufacturable designs.
This capability reduces downtime, improves reliability, and ensures our customers stay operational with high-quality, locally engineered harness replacements.
