Anyway, I was able do get started. This is the supplied DC high-voltage, high-current cable. It's called welding cable or locomotive cable, and is made up of hundreds of hair-sized wires, so it's very flexible.
EA is supposed to supply a cable lug crimper, but it hasn't shown up yet... I checked around at work with the electricians I know and found that Kelly Minton has a great hydraulic crimper. You can see the steps to make a solid crimp below.
You can see the crimper crimps from 4 sides for an extremely good connection. The final step is to put some shrinkwrap tubing and shrink it down.
I mounted the controller to the backing plate. This was heavy and messy due to the white heatsink compound. I built cables and mounted to the controller and the motor. The rest will come in when I mount the contactor in the box.
