I have a listing of the pinout definitions:

Connections and Wiring
----------------------

+5V Power and GND
+5V - +5 Volt from MS (Powers: Seq. Shift Lights, Nitrous Control, Launch Control, Dual VR Conditioning, and BOTH Table Switching)
GND - Ground for whole board

Dual VR Conditioning Circuit
T1 - VR Sensor #1 Input (To Base wheel - i.e. 2pin Wheel in rotary)
T5 - VR Sensor #1 GND /w Load Resistor
T3 - Conditioned Output for VR Sensor #1 [Pin 6 of U4 on MS Board]

T2 - VR Sensor #2 Input (To Reset wheel - i.e 24pin wheel in rotary)
T6 - VR Sensor #2 GND /w Load Resistor
T4 - Conditioned Output for VR Sensor #2 [Pin 11 on U1 on MS Board]

T1 and T5 should be for the 2 pin wheel
T2 and T6 should be for the 24 pin wheel

Sequential Shift Lights
T7 - Input #1 [Pin 11 of U1 on MS Board]
T8 - Input #2 [Pin 10 of U1 on MS Board]

T16 - Output 1 Relay
T17 - Output 2 Relay
T18 - Output 3 Relay
T19 - Output 4 Relay
T20 - +12V Power for Relays [To Battery]

Table Switching (Active High Input)
T21 - 12V Switched from Clutch Switch or Knock Circuit
T22 - Output [JP1 pin 6 on MS Board]

Table Switching (Active Low Input)
S1 - Active Low Switch Input [Toggle Switch to GND]
T38 - Output [JP1 pin 6 on MS Board]

Boost Control
T23 - Output [X4 Jumper on MS Board]
T24 - To Fast Acting Solonoid Valve

Water Injection Control
T25 - Output [X3 Jumper on MS Board]
T26 - To Fast Acting Solonoid Valve
*You must use one of the outputs in the Output circuits to X2 Jumper on the MS Board

Nitrous Control
T27 - Output [Pin 6 of JP1 on MS Board]
T28 - Anti-Lag Switch
T29 - Relay 1 Contact
T30 - Nitrous/Fuel Solenoids
*You must use one of the outputs in the Output circuits to X3 Jumper on the MS Board

EGT Logging
T31 - To K Type Sensor (Alumel [Red]) + ***Splice into a Ground from the Daughter Board
T32 - Cromel (Yellow)
T33 - Output [To X6 Jumper on MS Board]

2nd O2 Sensor Input
