Note: This plugin adapter uses only connector 1 on MaxxECU RACE/PRO units, for extra functionality, the second harness can be added to the RACE ECU.
The PRO ECU have in total of four ECU connectors which could be added for extra functionality: second harness, third harness and/or harness 4.
Run both engine fan and AC fan at the same time
Some high horsepower EVO VIII customers might want to activate engine fan and AC fan at the same time to cool down engine faster, you need to reroute
some cables in the harness.
Note: on EVO 7,8 MaxxECU GPO 1 (CMC 1: B4) is connected to AC clutch relay (pin 8) AND AC FAN HIGH (pin 32)
If you don't have AC, just simply cut the pin 8 wire and change the output function of GPO 1 in MTune to Engine Fan.
If you have AC (and inted to keep it), you need to move the AC FAN HIGH (pin 32) from MaxxECU CMC 1: B4 to MaxxECU CMC 1: B1 and activate that output as Engine Fan.
Note: Both fans will then be relay switched, aka PWM fan control will be lost of main fan.
This is just an example, of cource you can use any other available MaxxECU output to control the AC FAN.

ECU location and installation
Stock ECU is located behind plastic guard on passenger side floor.
1.Remove the plastic guard where the ECU is located.
2.Disconnect battery from vehicle.
3.Remove and disconnect stock ECU from vehicle harness.
4.Install MaxxECU adapter harness.
5.Route the included MaxxECU MAP-sensor hose to the intake manifold and connect into the MaxxECU.
6.Route wide band lambda cables to exhaust system, install lambda sensor in exhaust and wire the lambda sensor as instructed below.

Optional: Install external intake air temperature (IAT) sensor
Some vehicles are not equipped with an intake air temperature (IAT) sensor and MaxxECU plugin solutions do have the
option to add a sensor.
The intake air temperature (IAT) sensor should be mounted to sense fresh air flow going into the engine.
Depending on the intake manifold construction, the position of the temperature sensor is not given, but preferably mount
the sensor in the intake, or in the pipe before/after the throttle.
IAT wiring
MaxxECU plugin solution are equipped with an optional 2-pin connector for optional IAT wiring.
Mating connector and wires for external IAT sensor.
