Negative lead for your 12V setup, sorted in one piece. This Jaycar 4 gauge tinned lead is 450mm, black for the negative terminal, with tin-plated copper lugs crimped on both ends and colour-coded heatshrink sealing the joint. Tin plating means it won't green up in a damp shed, boat bilge, or outdoor install where bare copper would corrode within a season. PVC insulation stays flexible for routing around engines, fuse panels, or underfloor runs. Rated at 100A. Pair it with the red positive lead and your run's done
