It would be nice to know what exact spots on wiring loom (connectors, routes...) are they talking about. Maybe it's about wires bellow the tank. If there's something else, it'd be nice to know.
I doubt it's about front non-waterproof connectors, as this TSB is refering to L4, L5 and L6 models and new waterproof connectors were installed in the loom somewhere during L5 model production.
