    Default OBDII J1996/M conneted to Ethernet (RJ45) pinout

    We own several OBD2 Scanners that attach to DB9,s.

    A project we are doing requires us to pinout 2 OdbII (j1962/male) connectors to ethernet (RJ45).

    I am trying to pinout the Obd2 to ethernet with no luck

    anyone that can kindly assist us with the pinout for that?
    Below is how we connected a DB9. ( FYI )

    It tells you everything you need to know, to save you the trouble here it is.

    V2 RJ-45
    1 - 12V
    2 - CAN + (H)
    3 - CAN - (L)
    4 - GND
    6 - VPW
    8 - GND

    OBDII plug
    2 - VPW
    4 - GND
    5 - GND
    6 - CAN - (L)
    14 - CAN + (H)
    16 - 12V

    But if you are just going from RJ45 to OBD-II then why not use the supplied cable?
