Ryan - to go one step further, you should teach a proper technique on preparing the wires (Anderson's, spade connectors, etc.) as well as proper strain relief. A great mentor in NH on 2342, "Mr. T", teaches a technique (where applicable, depending on the connector) of crimp, solder, and shrink tube that I've never seen fail on robot in 5 years.

Also caution teams on long runs of unshielded PWM cables. A discussion on EMI/EMC/signal integrity is probably going to go over their heads, but "too long" needs to be something in their vocabulary.
