I just got the same one to replace my analog tstat. I haven't installed it yet as it just came today.
It comes with pigtails, stripped with wire nuts as the wires are soldered to the circuit board on both tstats. when you take the analog off the wall there should be enough slack that when pull up the wires from the tstat you see they are crimped to the outgoing wires. Simply cut, strip and wire to match the colors.
