    Aftermarket AFR Gauge

    New poster! (less than 10 posts)

    Okay,

    I have AFR gauge which has 3 wires
    red - ignition 12v
    black - ground
    grey - signal from o2 sensor

    Bosch Wideband Sensor LSU4
    Red - IP
    Black - VS
    Yellow - VS / IP
    White - Heater -
    Grey - Heater +

    Can anyone advise how i would wire the lambda sensor to the gauge and also how the spare wires would be connected ?

    i read that heater wires would be connected to 12v and ground ..??

    appreciate any advice or let me know if you need more info
    cheers

    You can't i'm afraid, you need a WB controller for an LSU4 probe (or NTK, or any other WB probe)

    Looks like the gauge you have is a narrow band one.
