12Volt Motorsports is a custom car wiring and performance vehicle electrical specialist based in Altona Meadows in Melbourne's western suburbs. We design, build, document and install wiring systems for show cars, muscle cars, classic restorations, drag cars, race cars and high-performance street cars.
Our work includes full vehicle rewires, engine bay wiring, ECU wiring, PDM wiring, CAN bus wiring, custom wiring harnesses, digital dash wiring, sensor wiring, bulkhead connector installation and complete electrical system integration.
We design and build complete wiring systems from the ground up, replacing ageing factory wiring, poor previous modifications and unreliable electrical systems with a clean, modern and serviceable wiring package.
This suits show cars, muscle cars, classic cars, restomods, drag cars, race cars, engine conversions and serious street performance builds where the wiring needs to be reliable, documented and built properly.
For performance and show builds, we specialise in clean engine bay wiring, hidden wiring, ECU installation, PDM wiring and power distribution systems that are designed around the vehicle instead of being routed as an afterthought.
We work with Haltech ECUs and Nexus VCUs, FuelTech ECUs, Holley Dominator ECUs, CAN bus systems, digital dashes, CAN keypads, sensors and power distribution modules.
Every wiring system is designed, built and tested in-house. Harnesses are bench tested before installation, then checked, configured and validated once installed in the vehicle.
We use professional wiring materials including Tefzel M22759/32 wire, Raychem DR25 heatshrink, Deutsch connectors, Sumitomo W5DL adhesive heatshrink and professional crimped connections.
Completed jobs can include documentation such as connector pinouts and wire colours, with build records retained for future servicing, fault finding and upgrades.
12Volt Motorsports supplies and installs the same professional wiring products we use in our own workshop builds. For complete ECU installs, full vehicle rewires and custom harness work, we commonly use motorsport-grade wire, sealed connectors, heatshrink, ECU plugs, sensors and power distribution components.
If you need a custom wiring harness, full vehicle rewire, ECU installation, PDM wiring, CAN bus wiring or clean engine bay wiring, contact 12Volt Motorsports with details of your vehicle and project.
Useful details to include are the vehicle make and model, engine combination, ECU or PDM being used, current wiring condition, intended use of the car and what you want the finished electrical system to do.
