No, I just changed the wiring harness, and the remote comtrol/Ford key worked perfectly. Just unlock the doors 2x and the tailgate unlocks. To lock the tailgate, lock the doors with the remote.
I have a 22 XL, and wanted the remote locking tailgate. All I had to do was replace the
XL wiring harness NZ6T-14B562 with the XLT equivalent. This was a very easy switch, just required
lowering the spare tire, and taking the back panel off the tailgate, then swapping the harness.
The parts...
It will show it is still in Mexico, UNTIL it arrives at a train depot near your dealership. . You should hear back from Ford about Dec 28, then it will take about 10 days to get to the dealer. Good luck
Don't get your hopes up. Getting scheduled is just the beginning of another wait. My 1/6/2022 eco boost XL was finally built Sept 9th, and has been sitting on a train, at the factory ever since. Nationwide train strike on the horizon, so Dec or Jan delivery MIGHT happen.
