How to wire AEM Map sensor,IAT,Boost,etc

[Flicktitty]

Cut the 3 wires going to your factory MAP Sensor (located on your intake manifold)

Wiring is as follows:

CAR HARNESS_____________MAP SENSOR
Blue/Red_________________Red____________5 Volts
Brown/Black*_______________Black__________Ground
Black/Yellow_______________Green__________Output

* on the 97-98 Supras the Ground wire is White/Black

This applies for both 3.5BAR and 5BAR map sensors from AEM.

Follow these instructions to wire in your sensors. (30-1100)

MAP Sensor
There are 3 wires on a MAP sensor. It requires MAP signal, 5V reference, and sensor ground. If you're using an AEM MAP sensor: MAP signal is green or white, 5V reference is red, and sensor ground is black. The signal wire needs to be dedicated, meaning that should be the only wire making contact with that pin. The sensor ground and 5V reference wire can be tapped. Please follow the pin out below to wire in your MAP sensor. If you did everything correctly, with an AEM 3.5 bar MAP sensor, your MAP voltage (setup/sensors/map sensor parameters) should be about 1.6V with the key on engine off, with an AEM 5 bar MAP sensor, your MAP voltage should be about 1.3V with the key on engine off. Remember to select the correct sensor in your MAP sensor wizard.

MAP signal - Pin 62B
Sensor ground - Pin: 28B and 65B (tap to one of these)
5V Reference - Pin: 41B (tap to this pin)

Air Intake Temp. Sensor
There are 2 wires on a AIT sensor. Polarity does not matter. It requires AIT signal and sensor ground. Please follow the pin out below to wire in your AIT sensor. Remember to select the correct sensor in you AIT sensor wizard.

AIT signal - Pin 45B
Sensor ground - Pin: 28B and 65B (tap to one of these)

Boost Solenoid
There are 2 wires on a boost solenoid. Polarity does not matter. It requires switched 12V and PW2 on EMS. Please follow the pin out below to wire in your boost solenoid.

PW2 - Pin 60B

Wideband (this is for EMS without built in wideband)
If you're using 30-4100 (Gauge type wideband controller), 30-2300/2301 (Dual/Single channel wideband controller), or other wideband controller with a 0-5V output, you will need to tap the 0-5V output wire to the O2#1 or O2#2pin on your EMS. White wire on 30-4100, and orange wire on the 30-2300/2301. Please follow the pin out below to wire in your wideband.

O2#1 - Pin 47B
O2#2 - Pin 48B
