After all the controls are mounted to the panel. All that's left is to wire it up. Here are some pictures of the wiring for the panel. It's is really much easier than it looks.

Soldering wires to the game pad is pretty easy. There are extra solder pads (with through holes) on the game pad that are clearly marked.
Here is a zoomed in shot of the wiring on the left side of the Sidewinder board. You can see the extra pads which are conveniently marked. There a couple of confusing identifications marked on the board. One is marked PR, which is the M button on the pad. There are also some pads labeled BR and BL. These are just auxiliary connections for the right and left trigger buttons.
When wiring to the pushbuttons, there are three connections for each switch. They are marked: 1-COM (Common), 2-NC (Normally Closed) and 3-NO (Normally Open). You only need to use two out of the three connections on each switch. The Common and Normally Open. The Common terminals of each switch are daisy chained together. The Normally Open terminal is the connection used for input into the Game Pad Board. Shown below is a schematic representation of the wiring.
