The black sleve / sheild you pulled off the old set of wires...put it back on the new one. I assume since there are so many wires down there, this is necessary protection. Push it up as far as possible to give yourself room to put the wires back in the connector. Get them all up snug in the connector, and simply slide the red locking plastic piece back in. Give a little tug to see if all lines are secure.
