Dash cams come both ways...5 volt and 12 volt. My wife's Maverick has a 12 volt dashcam, while my Maverick has a 5 volt dashcam. Our Transit has a 5 volt as well. Buck converters are used in our 5 volt versions.I have a dash cam that plugs into the cigarette lighter like most dash cams do. I think the problem with hard wiring the camera is that the voltage from the plug in at the lighter is reduced to 5 volts before it goes to the dash cam. Check before you put direct 12 volts by cutting out the connector, I'm just guessing that might be a problem.
