The AllSpark 120A Grey Anderson Plug Kit gives you everything needed to terminate a single heavy-duty DC power connection — the grey SB120-series housing plus two crimp contacts rated for 2 AWG (33.6 mm²) cable. Rated at a continuous 120 amps and up to 600 V DC, the grey colour-coding provides an instant visual identifier in multi-connector wiring harnesses, making it the connector of choice for high-current auxiliary battery circuits, DC-DC chargers, and solar charging systems across caravans, camper trailers, and 4WD builds. The robust glass-filled nylon housing offers excellent resistance to UV, heat, and vibration — conditions that are par for the course on Australian outback tracks and corrugated dirt roads.

Whether you're wiring a second battery system under your caravan chassis, connecting a portable solar panel array to your RV power centre, or hooking up a winch on your 4WD, this kit provides the correct-gauge contacts to handle sustained high-current loads without overheating or voltage drop. The hermaphroditic connector design means both ends are identical, so there's no chance of reverse-polarity connection — a genuine advantage when working in the dark at a remote campsite. Compatible with all standard Anderson SB120 housings from other suppliers, this kit integrates seamlessly into existing setups or new off-road and off-grid electrical builds.
