You need the adapter that places the wheel and pedals on two different
axies (is that the plural of axis?) of the same joystick. If you don't
have it, Thrustmaster will send you a replacement. I got mine within a
week of e-mailing them.
In the Win95 Joystick Control Panel choose custom. Choose 2 axis, 4
button, and for some reason Microsoft (in the Monster Truck Madness help
File) says not to choose any of the other options (not even the 'is a
racecar controller' option). You should then be able to follow the
on-screen instructions to calibrate it properly.
