The AllSpark Grid Wiring Kit is the complete, pre-terminated solution for connecting your vehicle's start battery to The Grid alternator-based power management system. Built with heavy-duty 4 B&S (21mm²) cable throughout, the kit supplies a full 6 metres of positive run — from the start battery through a 70A circuit breaker and a 100A heavy-duty relay, out to a 50A Grey AllSpark Anderson plug ready to mate with The Grid's alternator input port. Every cable arrives factory-terminated with the correct M6 or M8 ring terminals at each end, so there's no cutting, crimping, or guesswork on the side of the road. The 100A relay is triggered via a dedicated 6mm black ignition wire, ensuring the high-current positive line is only energised when the engine is running — protecting your start battery and preventing parasitic drain while camped.

Designed specifically for Australian caravanners, overlanders, and 4WD tourers who run The Grid power management system, this wiring kit removes the most time-consuming part of the install. Whether you're fitting out a HiLux, Patrol, LandCruiser, or a camper trailer, the generous 6-metre cable run gives you the flexibility to route neatly through the engine bay and into the cabin or chassis rail without splicing extra length. The 2-metre black earth cable connects the Anderson plug earth contact back to a solid body or chassis earth point, completing a properly earthed, high-current circuit. For off-road adventurers heading deep into the Kimberley, Cape York, or the Simpson Desert, this kit means your auxiliary power setup is wired correctly from day one — no undersized cable, no improvised connections, just a solid 12V foundation built to survive corrugated dirt tracks and the harsh Australian climate.
