Hello guys,very helpful site. I'm trying to wire up my AEM wideband into ECMLink for data logging. I'm a little confused as to which pin to use.
I know the white wire from the AEM wideband is the 5 volt out.
I'm guessing that I am going to use pin 75?
This is the part that confuses me.

- Rear O2 (ECU Pin 75)
- Front O2 (ECU Pin 76) - Only usable when “Open Loop” option is selected, or narrowband O2 simulation is enabled.
- MDP (ECU Pin 73)
- Baro (ECU Pin 85) - see IAT/Baro Notes below - Has internal pull down resistor making it unsuitable for certain sensors (see work around).
- IAT (ECU Pin 72) - see IAT/Baro Notes below
- Coolant Temp Input (ECU Pin 83) - (V3 only) - This will leave the car in “Open Loop”. “Lock Coolant Temp” must be selected, to work properly. Use only as a last resort and only temporarily unless you fully understand the issues.
