The P3 Analog Gauge *This gauge IS NOT plug and play. Boost/vacuum hose to the engine is required and wiring needs to be completed for power, ground, and optional analog inputs.4 Available Analog Readouts Analog boost (yellow/purple/black - dedicated plug for analog boost sensor) *boost tap not includedAnalog input 1 (brown wire - can read any 0-5 volt linear output sensor)Analog input 2 (blue wire - can read any 0-5 volt linear output sensor)Battery voltage (red wire / black wire - read through power and ground wires)optional auto-dim feature (green wire - connect to any circuit that gets power only when the headlamps are on and enable feature in the configuration menu for the display to auto-dim when the headlamps are on)Optional Add-OnsOBD2 power/ground tap harness allows you to connect to power and ground through your OBD2 port without any wire splicing (does not add OBD2 functionality)P3 ESVA (ethanol sensor voltage adaptor) allows your gauge to read ethanol content and fuel temp directly from any Continental/GM Ethanol sensor *Ethanol sensor not includedLC-2 Wideband o2 Sensor Kit allows your gauge to read your vehicle's Air/Fuel Ratio. Includes everything you need to add a wideband sensor to your exhaust.Any Other 0-5 Volt Linear Output Sensor Can Be Read oil pressure, oil temp, coolant temp, air ride pressure, egt, etc...OEM Vent OptionWe install the display in an OEM vent for your vehicle to make your install even easier.Analog gauge base kit includesIntegrated displayAnalog Box control unitMain harnessHard-wire harnessAnalog boost sensor *boost tap not includedApproximately 5' of 5/32" O.D. boost tubing with 5/32" I.D. hose at each end3 zip ties2 scotchlok wire tapsYou asked, we answered.The P3 Analog adds even more user control to what the P3 Boost-gauge already offered. We added 2 analog inputs so that you can bring even more information to your display without the need of your OBD2 port.There when you need it, hidden when you don't.No more bulky pillar or column pods... No more squinting to read tiny pixelated screens... While retaining the OEM plus design that blends into your interior, the P3 Analog packs a punch with it's bold, bright display that allows you to pick up info at a glance.Hot or Cold? No problem!Even though the P3 Analog installs in your air vent, we keep in mind that you need that heat and A/C while designing each gauge.Electronics in a harsh climate? We've got that covered too.We've torture-tested our gauges to the extreme. From frozen solid at -94 F to physically melting at hundreds of degrees, our gauges function far beyond the limits of the in-car environment. Part #AP3VGT4 / LAP3VGT4 / LAP3VGR4
