The remaining of the two sensor wires (black) then would need to go to the car body/battery negative? Is that right? I would hate to let the magic smoke out.

From memory I am pretty sure that is exactly how I did it, and mine seems to be reading correctly.

I have no idea what this means, but if you work it out let me know!
