    Question Pro Link cable to PLX wideband

    Hi all,

    I'm trying to wire in the Pro Link cable to the PLX wideband sensor, I have found a few different ways online, but want to run it buy the brains trust first (I'm pretty new to this).

    Pro Link cable- Black wire (ground)- to a good chassis ground point
    Red wire (analog 1)- to the 0-5v wideband output on the PLX
    Blue wire (analog 2)- Spare
    Orange wire (CAN high)- Spare
    Yellow wire (CAN low)- Spare

    PLX device- Power supply- Red wire (positive)- to the cigarette lighter positive feed, so it is live when ignition is on and uses the existing fuse
    Black wire (ground)- to a good chassis ground point

    - Analog output plug- Pin #1, 3.3VDC- Spare
    Pin #2, 0-1v Narrowband- Spare
    Pin #3, 0-5v Wideband- to red wire on Pro Link cable
    Pin #4, 8.0v- Spare

    Does this seem correct?
    Can I run/should I run the 2 ground wires (black wire on the pro link cable + black wire on the PLX power supply) to the same grounding point?

    Thank you for your time and help.


    Using:
    MPVI 2+ with Pro Link cable and pro feature set

    I also connected the Prolink black wire to a chassis ground. After rereading the instructions it appears it should be connected to the WB sensor ground. Has anyone connected the Prolink to PLX SM AFR successfully?

    How do I get output to gauge and chart to read AFR or Lambda? It currently reads voltage. Am I not understanding transform which appear to select voltage.
