22  - sense                                Z  GND for steering (steering pin 3)

For upright game, connect the following on the CPU board:

   18 to T and 19 to 20 to strap sound outputs 1 and 3 together
   15 to 16 and X to W to strap sound outputs 2 and 4 together
   7 to M for automatic game start (a start switch could go here)
   5 to 6 to account for lack of brake pedal

Audio outputs need to go to an amplifier (won't drive a speaker directly).
Gas pedal is a 5K pot.
