    MM3 Tuner

    Question for you folks with MM3 tuners.

    I know from previous vehicles and having connections to the OBD port that sometimes these connections continue to draw power with vehicles parked.

    Does the MM3 tuner draw continuous power when plugged into the OBD port?

    Reason I ask, I was in the garage fletching some arrows and then I see my dash lights come on in the truck for no reason.

    I recently installed the MM3 and that's the only thing I could think that would wake up the dash.

    Just curious, from previous dead batteries, I always unplug OBD connections when parked for extended periods.

    Thanks
