    I don't quite understand that. You want the black and white each connected to one terminal the heater element, and the bare ground connected the green screw in the housing. If the screws aren't meant for 2 wires, you want to wire nut the 2 blacks to a third short length connected to the screw. White and bare the same.

    Other than that, it is just how I would wire it.
