This P3 Analog Vent Gauge is specifically designed for 2015 - 2021 Subaru WRX and STI left - hand drive models. It fits seamlessly into your car's air vent, blending nicely with the interior while maintaining the vent's heat and A/C functions. You don't need to use your OBD2 port as it offers two analog inputs, bringing more information to the bold and bright display that you can read at a glance. Key features include analog boost/vacuum, analog battery voltage, an optional auto - dim or manual dimmer, and two universal 0 - 5V linear analog inputs. There are four available analog readouts: analog boost (yellow/purple/black plug, boost tap not included), analog input 1 (brown wire), analog input 2 (blue wire), and battery voltage (red/black wires). It also has an optional auto - dim feature (green wire). Please note that installation requires modifying your factory vent, and it's not a plug - and - play device. You'll need to connect boost/vacuum hoses to the engine and complete the wiring for power, ground, and optional analog inputs. The package includes a display, an analog box control unit, main and hard - wire harnesses, an analog boost sensor (boost tap not included), about 5' of 5/32' O.D. boost tubing, 3 zip ties, and 2 scotchlok wire taps.
Using this P3 analog multi - gauge is straightforward. First, make sure your car is a 2015 - 2021 Subaru WRX or STI left - hand drive model. For installation, you'll need to modify your factory vent. Connect the boost/vacuum hose to the engine and wire it for power, ground, and any optional analog inputs. Once installed, you can start using the various analog readouts. You can monitor analog boost, battery voltage, and use the two universal 0 - 5V linear analog inputs. If you want the auto - dim feature, connect the green wire to a circuit that gets power only when the headlamps are on and enable it in the configuration menu. As for maintenance, keep the gauge clean. Wipe it gently with a soft cloth. Check the wiring connections regularly to make sure they are secure. Also, be careful when handling the boost tubing to avoid any damage. If you encounter any issues, refer to the included documentation or contact customer support.
