How do we wire the Knsert? Pleas help!

Okay so I need help. This is my first time modding an arcade stick using FGWidget. I’m just really confuse on how to wire the KNsert. I have the solder and stuff. Like what do we do with with the wires? What do i do after I finish putting the KNsert with the wires into the button? Can someone please help? I’m not even sure which wire i have to get. Can anyone also link the wires i should get?

22 to 28 gauge stranded wire, you need 2 wires for each insert, one for +5 volts and one for ground.

You wire them up to the Widget as per its instructions.
