DCDC Wiring Harness
If you're wiring up a DC-DC charger or setting up a dual battery system, the right wiring harness makes the job straightforward. No chopping cables, no hunting down fittings, no second-guessing wire gauges. Just quality components bundled together so you can get it done properly the first time.
Our DC-DC wiring harnesses come with everything you need: heavy-duty multi-core cable, Anderson-style connectors, fuse holders, ignition wire, and proper cable protection. It's all sized correctly for the job and designed to handle Australian heat, dust, and rough roads without missing a beat.
Whether you're installing a charger under the bonnet or running power through to a canopy setup, the plug-and-play design takes the guesswork out. The Anderson connectors make it easy to disconnect your system when you need to, and the braided cable sleeving keeps everything protected from abrasion and the elements.
Our harnesses are built to work seamlessly with our chargers and battery boxes, but they're also compatible with most common setups. If you're building from scratch, pair one with our 50A wiring kits to complete your electrical system with quality components throughout.
Installation is simple enough for most people to tackle themselves, and the included fuses and terminals mean you're not making extra trips to find parts. Mount it, connect it, and get back to planning your next trip instead of troubleshooting electrical gremlins.
