so going by your pinout:
1:
[blank] [blank] [1Q to 1J] [blank] [blank] [blank] [blank] [Pin 31 - spark output] [blank] [blank] [blank]
[clutch input (js7)] [blank] [fan control] [blank] [blank] [blank] [1J to 1Q] [IGN PIN] [blank] [blank] [12v]
2:
[blank] [IDLE] [INJ 1&3] [blank] [COOLANT] [blank] [blank] [blank] [blank] [CAS - pin 25] [CAS] [GRND] [GRND]
[blank] [blank] [INJ 2&4] [blank] [blank] [AIT] [O2] [blank] [blank] [blank] [blank] [GRND] [GRND]
db37 needs to match this:

you need to ignore the TPS wiring and the wire on 1C. the wire on 1C is after you build a special circuit for the fuel pump. I thought you said you had a diypnp????
