On page two of the Spike manul, it tells you most of what you need to know. The black wire going into the spike is the ground wire, the red wire controls the M- terminal, the white wire controls the M+ terminal. So you wire the black wire to one a ground pin on one of your digital outs, and you wire the red wire to a Signal pin on one digital out, and the white wire to the Signal pin on the second digital out.

How you wire it depends on if you have some terminal crimpers and 3 position female SIP connectors, a soldering iron and some patience, or some wire nuts and absolutely no patience at all.
