I know about it, $1.50 is not the point, but waiting time for the order is few days, makes no sense as long I can install without. Since You bought specially made wiring harness, I understand why I faced this kind of troubles with the sensors. I just spoke with the dealer and my VIN shows for SENSOR. Park Assist outboard: 6MT25TZZAA. For the Laramie with Parallel & Perp Park: 5YV69TZZAA, same as ordered and received.
Now is clear where was a problem, there are 2 settings to be changed for semi parking, not 1:
VehConfig 1: PTS configuration: Semi Automatic
VehConfig 5: Semi Automatic Parking System Present: Yes
I need to update my instruction in @tbd0021 second post.
@sportgd, thank You for Your finding!
