ECM
The Engine Control Module (ECM) is environmentally sealed and can be mounted under hood, however, avoid extremely hot locations (exhaust, etc.)
or high splash areas. It is not recommended that the ECM be mounted directly to the engine.
Accelerator Pedal
Mount the accelerator pedal per the following dimensional guidelines, mounting details are application-specific and are left to the user. Ensure that the
pedal is securely mounted to the vehicle. A grommet is required in any sheet metal hole that the harness routes through to avoid wire damage.

Mass Air Flow (MAF) Sensor
NOTE: It is critical that the MAF sensor is mounted per the instructions below. Vehicle performance and/or drivability may be affected if it is not
mounted as recommended.
The mass air flow sensor must be installed in the induction system using the supplied MAF sensor mounting boss. The induction system should be 4
inches in diameter and have a minimum straight section 6 inches in length. Mount the MAF sensor in the middle of the straight induction section,
ensuring that the middle of the mounting boss is at least 10 inches from the throttle body.
The MAF sensor must be oriented correctly in the induction system - note the arrow on the sensor indicating flow direction. Be sure to weld the
mounting boss correctly - the sensor will only mount one way in the boss (see diagram).
THE MAF MAY NOT HAVE A FLOW DIRECTION ARROW ON THE TOP. THE CORRECT ORIENTATION OF THE MAF IS AS SHOWN BELOW:
Weld the boss in place before installing the sensor. When installed in the vehicle, the MAF sensor should be mounted with the connector end pointing
between horizontal and fully upright – do not mount with the connector oriented downward.
