Anyone soldered a neo12 to a ver 9? Help!

[eejit mk1]

Hi, I'm a noobie and couldn't find any info on a search so I thought I'd post. I bought the chip and kit- Neo 12 for ver. 9 PS2 silver.

Can't figure the diagram as there seems to be 21 solder points and it only requires a 12 wire solder. Could someone explain to me please. I'm a virgin at this caper.
This is the diagram here :

and where does the two yellow wires go ? Ground and....positive?

Thanks awfully
