Installed it last weekend. I used a multi-meter to verify the correct wires behind the fuse panel, just forgot at first that it was set to two-stage unlock, had to hit the unlock button twice to verify. I ordered the Pop & Lock from Amazon and it did not contain the shorter wire for inside the tailgate, so I had to get a replacement unit.
Also, they changed the wiring, it is no longer two wires inside the corrugated plastic loom, it came with a cable containing the two wires. I decided to add some of the plastic loom where it goes through the tailgate jam and also into and out of the frame.
On the 2014 Supercrew, the grey/brown stripe wire connects to the green and the violet/grey stripe connects to the blue.
