    Hp tuners monitor a ground switch?

    I have mpv1 pro and want to know if it can monitor a hobb switch.

    The switch completes a ground circuit.

    I can have that turn on a led too, but want to know if I could set up in the scanner to see it go from on/off.

    Grounded vs open

    What I mean is:

    Can I hook up the ground wire from the switch that triggers the pump to the scanner.

    Read it in the scanner as on (ground present) off (no ground present)

    Would look like this in the chart. ____/````````````\______ (up its on (1) at bottom is off (0)
