Supercharged
I couldn't spot anything that it may plug into. Is just a 2 terminal connector, unfused, going from the battery (guessing from the terminals on the other end) to seemingly nothing. One of the guys here reckons it's for a trickle charger/battery tender, but I think the wires look rather flimsy for that. Will have a bit more of a look around tomorrow as well as have a bit of a peek at the wiring diagrams to see how the fuel sender is wired.
