  • LSU 4.9 Wideband O2 question

    Wondering if anyone has the answer to this question.

    I am wiring the wideband voltage signal through the PCM A/C pressure sensor wire (red). I don't have an A/C after the turbo install and decided that would be the best route. It is for the HP Tuners Scanner for data logging wideband.

    I have a Glowshift Wideband gauge (cheaper I know, but it works) and it uses the LSU 4.9 wideband sensor.

    What wire would I splice from the sensor to send the voltage signal into the A/C pressure wire to the PCM? Or is this a wire that needs to come from the controller box?

    Thanks
Working...
