Make and model of alternator ?
Some need a sensor wire, some don't.

IIRC the two large are for positive feeds, use either or both and the small one would be for alternator warning lamp.
If you go to a good auto electrics supplier you should be able to buy a new din plug fitting kit with new terminals to fit. If its from the old Lucas
ACR series alternator.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

Jollygreengiant is correct.
Two large connections are the same and are the positive feed back to the battery.
Small connector is from/to ignition light.
When ign is swithced on, current flows from battery thro ign light to alternator, to energise stator coils - creating a magnet. Once engine is
started, alternator supplies its own current for the stator coils and thereby feeds 12v back out the small terminal to extinguish ign light. (12v on
both sides of the bulb).

lotustwincam is right.
the two big blades (6.8mm) are commoned - usually you need to use one with small - 60 amp or less output alternaotrs; for bigger ones, like land
rovers, you'd wire both in parallel to allow fatter wires to handle the larger currents.
smaller one is 4.7 mm. VWP sell the connector or use 2 or 3 spades.
