This following is the guide for the connecting the Apexi SAFC II to your cars' ECU based on non-KARMANN sensor:

Wire from SAFC II:
Red - Power
Green - RPM
Purple - Knock Sensor
Grey - Throttle Position Sensor (TPS)
Brown - Ground
Black - Ground
Yellow - MAF output
White - MAF input


1993 240sx speed sensor at ecu: yellow/green wire (32)

ka24e/ka24de ecu:
Power – black white
Rpm – yellow/red stripe
Knock – none
Throttle – white
Ground – black
MAF(air flow) – white

sr20det ecu:
Power – black/white (47)
Rpm – red/white (8)
Knock – white (27)
Throttle – white (20)
Ground – black (17)
MAF(air flow) – white (16)

here is a link to the ecu pin outs:
