The single row plug went right in, no issues. They both physically snap into the door moulding. Second time around installation was about 30 minutes, first time was an hour trying to find all the screws to pull and not using a fish tape to pull the wire. Shoving a limp wire that catches on everything you cant see was the most frustrating part the first time...I highly recommend using a pull wire to pull it thru as the christmas tree pins get caught overything and you cant fit your hand in there to free them.
Ive got an RL3Z-14A626-AA keypad new, as shown above if anybody has the 2 row plug like the poster who showed the invoice had...$50 shipped takes it.
