Verifying proper voltage and polarity before plugging anything in for the first time should be standard practice.
If the problem is that the initial wiring was done incorrectly, I don't think a diode would help. It's just as easy to install the diode backwards, or in the wrong wire, as it is to swap the wires when first connecting them. You need to double-check the final connection anyway, and I think it is a lot easier to have just one thing that could be done wrong and which is easily corrected.
