When you had a look once you took the lining off you probably saw space for the two oval shape thingy's to sit in.
the black connector block is part of the whole connector block from the interior map light. Dont worry about this in the pic as its been chopped off from source.
when you get yours all you have to do is follow what position the contact is in from the conerctor block. (i think no.6)?
Unlicip the connector block, remove the connection from it and install it in yours. Remember to ground the earth. You will see a bunch of earthings in the middle of where the map light sits in the roof.
Brilliant thanks for the advice guys.
@GFP - I may take you up on that offer mate, car goes in for spraying next weekend so earliest I could get up would be weekend after. If nothing else pops up in coming week i'll give you a shout to arrange a visit.
