I had to wire in the power supply cable for the Power Box that I situated in the gap behind the wheel arch in the tub; it took 40 minutes and a half-dozen cable ties to route the Power Box''s pre-terminated and fused 5m in-vehicle charging cable. And as everything else – battery monitor, DC-DC charger etc. – is already wired in, that was it!
