Wiring the Controls
Please note some changes as of 7/8/99, that I've made in the wiring and pin assignments. These changes have made it possible to use just one switch for single to dual axis switching instead of two.
In single axis
1. Use of the +5v output of pin #9 instead of pin #8.
2. Pin #6 now connects to the left brake lug instead of the right.
3. Pin #9, instead of pin #8, now connects to the center brake lug. 
In dual axis
1. Pin #6 now connects to the left brake lug instead of the right.
2. Pin #11 now connects to the left gas lug instead of the right.
This diagram illustrates a single axis setup, which works the same as a joystick. In other words, you cannot accelerate and brake at the same time, because they're on the same axis. Obviously, you cannot push forward and pull back on the stick at the same time. If you want to have both work simultaneously, or to use the "Heel&Toe" Ayrton Senna technique,  then you must use a double axis setup. Go to the second diagram, which is right below this one, for double axis wiring. I've also added an analog clutch to this diagram for games that support it.

A DPDT slide switch looks like this and has 6 terminals on the back of it.
Axis Switch

This is a very simple switch that can be placed on your wheel unit, which allows you to select either a single or dual setup. Some sims allow for only single axis operation, while others accommodate both single and dual. This switch makes it easy to enable either one without having to rewire your pedal unit.
