| INSTALL | PLUG & PLAY BOOST GAUGE: ALFA ROMEO GIULIA/STELVIO 2.0L

The following guidelines are instructions for installation of the VAITRIX Plug & Play Boost Gauge for all ALFA ROMEO Giulia and Stelvio 2.0L equipped vehicles.

PARTS FOR INSTALLATION:

• - Vaitrix GEN2 Gauge
• - Vehicle Specific Harness plugin
• - Red positap
• - Ring Connector
• - 3M sticky pads for mounting
• - Gauge Pod stand
• - Remote control

The following wire routing and gauge mounting are recommended (and where we found the most convenient locations). You are free to mount the gauge 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.

1. Disconnect your negative battery terminal (located in trunk).

2. Remove engine cover.

3. Below is the sensor location we will be working with. You need to remove the piece of engine shielding in order to access the manifold sensor.

4. This is the Manifold sensor. Take the Vaitrix MAP sensor boost gauge harness. One side connects to the sensor on the manifold, the other side connects to the factory connector.

This part of the wiring harness will make it's way back to the gauge and plug in at the back. 

5. Locate a pass through to the cabin. The below location is recommended.

6. The gauge wiring harness consists of a black, yellow, red, and blue wire. We will not be using the blue wire. The black wire is for ground, red wire is for 12V power for gauge memory storage, and yellow wire is for the ignition power.

7. Connect the black ground wire to a reliable source. We recommend below.

8. Open the fuse box access panel on the passenger side cowl. Remove the box cover. This is where you will source your 12V power and connect the red wire from the gauge wiring.

9. The yellow ignition power wire will connect to the wire cluster harness on the passenger side of the engine bay near the ECU. Use the positap to tap into the wire below.

10. Once you have the gauge mounted and wiring connected, reconnect the battery in the trunk. 

11. Reconnect your battery, and turn on the ignition. The gauge should power on, and then read near zero. If the gauge is flashing alternately, this means you need to double check your connector at the sensor or power/ground for a solid connection.
