The following guidelines are instructions for installation of the VAITRIX Booster ECU for all FIAT 500 ABARTH and 500T models. 


  • - Vaitrix Booster ECU Unit with Universal Harness (Basic or Pro)
  • - Vehicle Specific Harness
  • - Bluetooth Module Cable
  • - Red positap
  • - 3M sticky pads for mounting


Remember to disconnect your negative battery terminal before proceeding with installation. 








1. Remove the engine cover/air box. This will make getting to the sensors much easier. In order to access the ignition power, camshaft sensor, and boost pressure sensor on the charge pipe, you can also remove the battery and battery tray (caution, the ECU is attached to the back of the battery tray).


2. Below are the sensors we will be locating and working with:


  • A. Manifold pressure sensor
  • B. Boost pressure sensor (on the charge pipe)
  • C. Camshaft sensor (located underneath the PCV housing and vacuum pump, on the side of the engine.













3. The harness and connectors that attach to the factory sensors are apart of the vehicle specific harness. This harness connects to the universal harness for the Booster ECU. 

Once you have mounted the Booster (we recommend either on the back of the battery on the ECU, or on the fuse box in the engine bay), you can connect the vehicle specific connectors to the universal harness. These connectors only attach one way, but make sure you match up the correct attachments.



4. After mounting the Booster ECU, and connecting the vehicle specific harness to the universal harness on the Booster, you need to find ignition power for the red power wire coming from the universal harness. We recommend the wire below, which is located down and in front of the battery. Use the posi tap to connect to this power source.




5. On the camshaft sensor connector harness, there is also a ground wire. This needs to be connected to a reliable ground. We recommend the negative battery terminal.




6. On the universal harness, there's a 4 pin connector and 2 pin connector that have not been used, and are shorter in length. These are for the bluetooth module. Take the bluetooth module and connect to the two together. Route the bluetooth module to a location that will deliver strong signal (do not place below large components or parts of the engine).







8. Now reconnect your battery, and turn on the ignition. Ensure no CELs or DTCs are present. The most common lights to see are codes for barometric pressure and sensors. If this is the case, double check your connections and ensure your power source is well connected.
