If you’re a car enthusiast, you might have come across the Apexi SAFC, also known as the Super Airflow Converter. The Apexi SAFC is a piggyback air/fuel controller that allows you to adjust and tune your car’s air/fuel ratio. In this article, we’ll discuss in detail the Apexi SAFC wiring diagram, which is crucial to install it correctly.
What is Apexi SAFC?
Before diving deep into the Apexi SAFC wiring diagram, let’s understand what it is and how it works. The Apexi SAFC is a device that modifies the signal from your car’s Mass Airflow Sensor (MAF) or Karman Vortex Sensor (KVS). It intercepts the signal and changes the signal’s frequency and voltage to adjust the air/fuel ratio.
The Apexi SAFC is widely used in car tuning to adjust the air/fuel ratio, which is crucial for your car’s performance. It can either enrich or lean out the air/fuel mixture, depending on your tuning preferences. However, to install the Apexi SAFC, you need to understand its wiring diagram.
Apexi SAFC Wiring Diagram: Understanding the Basics
The Apexi SAFC wiring diagram is a crucial aspect of installing the device correctly. It’s essential to have a wiring diagram to connect the device to your car’s ECU and power supply. The wiring diagram consists of different wires with different colors and functions. For example, the red wire is the power supply while the white wire is the ground wire.
To install the Apexi SAFC, you need to connect the device to the Powertrain Control Module (PCM), which controls your car’s fuel injection system. The wiring diagram shows you how to connect the device to the PCM and the power supply.

| Wire Cutters | 1 |
| Wire Strippers | 1 |
| Electrical Tape | 1 roll |
Step 1: Disconnect the Battery
Before starting the installation process, disconnect the battery to avoid any electrical shock. Use the wire cutters and disconnect the negative terminal of the battery.
Step 2: Locate the PCM
The next step is to locate the Powertrain Control Module (PCM) of your car. The PCM is typically located near the engine, and it controls the fuel injection system. You can refer to your car’s manual to locate the PCM.
Step 3: Connect the Wires
The Apexi SAFC wiring diagram consists of different wires with different colors and functions. To connect the wires, strip the ends of each wire using the wire strippers and connect them according to the wiring diagram. Make sure to connect the wires to the correct terminals of the PCM and power supply.
Step 4: Power Supply Connection
Connect the red wire from the Apexi SAFC to the ignition switch’s ACC terminal to provide power to the device. The black wire should be connected to the ground wire.
Step 5: Final Testing
Once you have connected all the wires, test the Apexi SAFC by turning on the ignition switch. The device’s LED light should turn on, indicating that it’s working correctly.
