Lambda #1 and Lambda #2 plugs are for connecting UEGO wideband Bosch LSU4.2 sensors (AEM 30-
2001) for 2003-2004.5 models only. The UEGO extension harness (AEM 30-3600) mates the adapter
harness to the sensor (1 required for each sensor used). The AEM Infinity EMS supports the OEM
UEGO sensors on 2004.5+ vehicles through the plug and play harness. The Lambda #1, Lambda #2, and
Battery+12V connections above can be ignored on 2004.5+ applications (assuming the OEM UEGO
systems have been left untouched).
AEMNet is an open architecture based on CAN 2.0 which provides the ability for multiple enabled
devices, such as dashboards, data loggers, etc., to easily communicate with one another through two
twisted cables (CAN+/CAN-).
The 2-pin Flash Enable connector is used as a
secondary hardware flashing option by jumping the
two wires together using the included shunt
connector. Note: Flashing will normally be performed
in the software not using this connector.
Integrated in the 350Z/G35 PnP harness is an
“auxiliary” connector. This is a Deutsch DTM 12P
connector (shown on right) and is used to adapt many
common ancillary inputs and outputs easily. Included
in the kit are a DTM 12P mating connector, 12 DTM
terminals, and a DTM 12P wedgelock. If used, these
components will need to be terminated by the
installer or end user with 16-22awg wire (not included). Note: Pin numbering is molded into the
connector, as shown.
Available I/O Typical Use Notes Component Wiring
Fuel Press This is used for monitoring
fuel pressure input to the
Infinity. It can also be used
to increase or decrease
injector fuel pulse to
compensate for a failing
fuel pump. Typical electronic fuel
injection fuel pressure
varies from 30-100psi. AEM carries 0–5V
fuel pressure
sensors (sold
separately). This w ire goes
directly to the signal
w ire of the pressure
sensor.
Air Tem p Air temperature is typically
used for fuel and ignition
timing correction. The 350Z/G35 comes
standard w ith a MAF
sensor w hich has an
integrated intake air
temperature sensor. This
w ire is run in parallel w ith
the stock sensor. This
means if an aftermarket
sensor is to be w ired
using this pin, the factory
MAF sensor must be
disconnected or else the
signal w ill be skew ed
drastically. AEM carries air
temperature
sensors (sold
separately).
How ever, the
Infinity can accept
any thermistor
sensor and can be
calibrated in the
Infinity Tuner
softw are. Intake air temp
sensors have tw o
w ires w ith no
polarity.
