Hori Fighting Stick V3 Mod Help.

Hi, I recently got a Hori V3 and I decided to mod it.

I have my new 30mm Sanwa buttons and I know how to de solder and solder everything back together, but I came upon some photos of someone else modding this.

It shows everything wired back up. It shows that he got rid of the Daughter Board and has cut all of the wires. What did he use to connect the wires to the buttons and the motherboard to the black wires on the buttons?

I'm completely new to modding, thanks for any help!

Also, where did he get his terminal blocks?
