ECU PINOUT DATABASE
ECU PINOUT DATABASE
I would like for a moderator to place this as a STICKY or in the TECINFO section. This is very helpful information. This site has the ecu pinouts for many different cars, as well as OBDII, OBD1 and pre OBD 240sx's.

For reference, here are the extras. Taken from 89-94 USDM 240sx FSM. No guarantees on accuracy. Also note that the ECU connector shown on the above website is pictured from the harness side, or looking into the ECU.
!EN is active LOW output: when this pin is low(ground) the device will then enable/turn on
!IN is active LOW input: when low(ground) this signifies the device is active.
1: power transistor NPN base output
3: to dropping resistor to NPN collector
8: EGR Temp Sensor
9: condensor fan !EN
11: AC condensor !EN
12: A/T
22/30: CPS Signal 1
24: CEL !EN
25: Swirl Control Valve sol !EN
27: Knock sensor input
28: A/T

This one should be pretty accurate I went threw the 91 wiring diagram, I did find a few in inaccuracys from other pinouts, cant remember which ones but this is pretty much straight out the 91 FSM.
