Default obd1 ecu harness questions

ok i purchased 2 obd-1 ecu clips w/ 8+" of wire.

i have a couple questions.

i'm told both are from a DX. Yet both have vtec wiring (no Knock sensor as they're d series). This mean they're from a 92 right?1

1. according to pinouts i see there should be 2 Grn/Yel wires are pin a7 and a8. one harness has this, one doesn't. Pinouts say these are "Fuel Pump". anyone got some details on that?

2. pin a21 and a22. a21=ICM, a22=ignitor
one harness has both, one has a21 only.

3. According to my pinouts D11 (TPS Wire) should be Red/Blu. But one harness it's Light Green and the other it's Pink/blk..

4. on my pinouts there should be a Wht/Yel wire @ D16. the pinout says VREF/Empty. Im guessin that is a b-series only wire?

5. what is the "Data link connector" (pin d7)

thanks
