Help installing MODCHIP

[WAKIM]

I just received the MODCHIP I ordered from MODCHIPSS.COM. I do have sodering experience, but this board is more compact than anything I have previously done. I had looked at someone's site and thought I was supposed to push the wires through the board and solder on the back. I am fine with this. In looking closely at the diagram it looks like they want me to solder to the peice of metal (don't know what you call it) between the chips and the board (what connects the chips to the board). Any advice. I did E-Mail support, but any help would be appreciated as my PS2 is currently in pieces and I want to get it back to gether ASAP.

Thanks
