Video board, 30 pins, 15 per side, numbered side is back of board, letters
are on component side. Items in parenthesis aren't listed on schematic:

1 Ground A Ground
2 +5 volts B +5 volts
3 (ground) C (ground)
(keyway)
4 (ground) D (ground)
5 (ground) E (ground)
6 (ground) F (ground)
7 (ground) H (ground)
8 (ground) J (ground)
9 Red K (ground)
10 Green L (ground)
11 Composite sync (inverted) M (ground)
12 Blue N (ground)
13 Video return P (ground)
14 + sense R (+5 volts)
15 - sense S (ground)

CPU board, 44 pins, 22 per side, numbered side is back of board, letters
are on component side. Items in parenthesis aren't listed on schematic:

1 Ground A Ground
2 +5 volts B +5 volts
3 (ground) C (ground)
(keyway)
4 Ground for shifter D Ground (coin door 1)
5 Ground for brake E Ground (utility panel 4)
6 Brake F Gas pedal wiper
7 Start 0 H Steering 2 (steering pin 1)
8 Steering 1 (steering pin 4) J Right coin counter 2 (utility panel 6)
9 Left coin counter 1 (utility panel 7) K Test switch (utility panel 5)
10 Service switch (utility panel 9) L Coin 2 (coin door 2)
11 Coin 1 (coin door 3) M Start 1
12 Shifter N (ground)
13 (vol. gnd) P vol. gnd for gas
14 (vol. vcc) R vol. vcc for gas
15 Sound 2+ S (ground)
16 Sound 4+ T Sound 1+
17 (ground) U Audio ground for channels 1 & 3
18 Sound 3+ V Audio ground for channels 2 & 4
19 Sound 1- W Sound 4-
20 Sound 3- X Sound 2-
21 + sense Y +5 for steering (steering pin 2)
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.

I've never tried doing this before and don't know if you also need
power/audio board hookups or not. If you are using a switching power
supply instead (REAL good idea) you will need another way to drive the
speakers. It is also assumed you are trying for an upright cabinet and
not a sitdown. For all I know, you might be trying to make the worlds first
COCKTAIL Pole Position---if so, mount a couple fans!!
