    Default connecting 5v pressure sensor directly to v2

    not sure if this forum is active but I have a general question..

    If I wanted to connect a 0-5V pressure sensor directly to the V2, does the V2 source the 5 volt power to the sensor? or can I just only run the signal back to the V2 and I need to find my own 5V source?

    Also generally looking for more info on connecting directly to these ports on the V2, like pin outs and such.

    Found this on Page 104 on the EFILiveV75Scan.pdf.

    You will need a 5 Volt source from the PCM to power your sensor.

    FSV2 does not provide 5V output, you have to provide your own.

    FSV2 only provides signal input and signal ground.
