W8 Passat Interior Light Installation

Is the mk4 golf interior light just simply plug and play?

I like the idea of having 2 extra 'reading' lights.

Can anyone tell me how many wires I need to buy for fitting this, and the type of wires I need?
Will be going up to TPS for all the bits in one go and don't want to be halfway through fitting and be missing a wire!
( a part number might be easier when ordering if anyone has that )

A must, thank you

didnt know this was possible. might take it to a garage to get done
