I'm going to use an M4-ATX to get the nice regulated 12v into my Lilliput EBY701.
Just curious, if i ground the lilliput to the car chassis or the ground of the actual molex where i'm getting the power from.
being that your going to use the m4 for power, i would recommend to ground it to the m4's wires.
My OLD 2001 Mitsubishi Eclipse GT:
"The Project That Never Ended, until it did"
next project? subaru brz
Always ground to the power source.
