(left picture).You only actually need the neg to ground if you want the measure the voltage as well, if you want to do that then load needs to be on the neg side as you say otherwise don't think it matters though I'll check that later to make sure. I prefer using ads1115 for voltage as you can measure differential voltage between to points so no risk of ground loops.
