Help. Can't get blind spot to work when cargo box attached.

@GeorgeGG i think you’re onto something - maybe it needs time to calibrate

Is it a trailer you are towing or a box that fits on the trailer hitch. If a box on the trailer hitch and your rears lights can be seen from behind, then I wouldn't worry about hooking up the 4 pin. From what I see all that is is doing is running up your trailer towing miles.

It is a box, but it is huge and may cover tail lights (depending on what angle you are looking from). It also covers the license plate, so that needs to be relocated to the back of the box and lighted at night. Anyway, it started working now.

@Fizzy . Yep. If it needs time to calibrate, I wish Ford would have said so in the manual. Would have saved me many hours. But I am glad it is finally working.
