| INSTALL | BOOSTER ECU: Jeep Wrangler JL 2.0L

The following guidelines are instructions for installation of the VAITRIX BOOSTER ECU for all JEEP WRANGLER JL 2.0L equipped vehicles.

PARTS FOR INSTALLATION:

• - Vaitrix BOOSTER ECU
• - Universal Harness
• - Vehicle Specific Harness plugin
• - Add a Fuse connector
• - 3M sticky pads for mounting
• - USB Tuning cable or Bluetooth Module (if applicable)

 The following wire routing and mounting points are recommended (and where we found the most convenient locations). You are free to mount the unit and run the wiring in any location you prefer, the provided power wiring and ground should be long enough to reach many locations. You can also add on to any wiring if necessary.

Make sure to disconnect the battery before working with the engine sensors on the car. 

1. Remove Engine Cover. Loosen the (2) bolts at the front of the cover, and pull engine cover up and off.

2. Remove the side cover. To do this, remove the (2) bolts near the top, and pull up and out. This needs to be removed in order to more easily access the MAP and Boost Pressure Sensors.

3. Now you will take the vehicle specific harness and begin connecting to sensors on the car.

There are (2) parts to the vehicle specific harness. One harness connects to both the MAP sensor and Boost Pressure sensor for boost readings. The other harness connects to the Cam Position sensor, and has a black wire for connection go a ground.

Below is the sensor locations:

A. MAP sensor

B. Boost Pressure sensor

C. Cam Position Sensor (located underneath the charge pipe that runs across the top of the engine. It is possible to get to the sensor without moving the charge pipe, but easier if you do so, we'll detail that below).

A. MAP Sensor

B. Boost Pressure Sensor (located on charge pipe, near the throttle body)

C. Cam Position Sensor

 
If getting to the Cam Position Sensor is easier for you with the charge pipe removed, below is what you will want to loosen or remove. You don't need to take the entire piece off, just remove or loosen enough to move it out of the way.

You can loosen the clamp for the chargepipe at the throttle body. This will allow you to pivot the charge pipe to move it out of the way.

Once you have connected the Cam Position Sensor, complete the rest of the sensors with the vehicle specific harness. Ensure that the charge pipe is put back into place and is secure with all attachments and hoses.

4. Connect the ground wire attached to the cam position sensor harness to a solid ground location, there are many in the engine bay. We simply recommend the negative terminal on the battery, but you can ground anywhere that is easy to access.

 5. Connect the vehicle specific harness connections to the universal harness, which will lead back to the Booster ECU. Again, these connections only fit one way and are all different, so it's difficult to get them mixed up.

6. Mount the Booster ECU using the 3M pads to the location of your choice. We recommend the top of the fuse box on the passenger side of the engine bay.

7. Next, you will need to connect the red power wire from the Booster ECU to a source of ignition power. The best place to take ignition power from inside the engine bay is inside the fuse box. 

Use the provided add a fuse, and simply tap into the fuse location below.

Once this is completed, you can begin to button up the engine bay.

The tuning map comes preloaded on the Booster ECU. You will want to re-connect the battery and turn on the ignition once the installation is complete. Make sure there are no CELs or error messages. If one appears, double check your connectors to ensure that they are all seated properly, and connected correctly. 

If all is clear, you have completed this installation and are ready to take a test drive.

If using the bluetooth module, take the provided bluetooth module, and connect to the (2) bluetooth connectors on the universal harness of the Booster ECU. One connector is a (2) pin, the other is a (4) pin connector, they are near each other.

You can route the bluetooth receiver anywhere in the engine bay, but we recommend a place where it will not be too covered or buried, which will result in a weak signal.
