Subscribed to the thread. So is it safe to assume if you have tow tech, tow pack w/360 or Max tow w/360 that you get this harness and sensor set-up versus the old sticker method.
Sort of. You still get the sticker kit but apparently we are waiting on a software update to configure the sticker. In the meantime, the harness with the sensor attachment appears to only apply to 5th wheel or gooseneck trailers. I can't get anyone at Ford or this thread to confirm that -- can you setup the sensor attachment on a conventional trailer?

Ok that makes more sense...stickers remain for conventional trailer and harness/sensor is for 5th Wheel/Gooseneck. Surprised that the sticker config is not already good to go since I assume it's the same technology from 2020. That is one of the top few reasons for me getting my 1st ever F-150. Hybrid, ProPower, Towing/Payload for my travel trailer needs and ultimately all the tech including all the back-up assist.

My 2017 came with like 5 stickers and I only used 2 so I'm taking 2 to my new one in case it doesn't come with any. Hopefully if I get the "software update" I will be good to go.

It still seems baffling if the sensor doesn't work on conventional, and what do folks do with more than 1 trailer, it just seems shortsighted.

Yea my 2016 XLT had the stickers and it worked great. Same stickers come with the 2021– you get a pile of them. Probably 5 but I didn’t count.

Finished setting up the airstream and hitch connections to the new Platinum today. I was happily surprised that I didn't have to adjust the weight distribution hitch, other than change the ball height!

Now to the stickers: Just like everyone else, I have a sensor and harness and a pack of 6 stickers. The manual states that once we get an available update to the truck, which the truck is eligible for, the Pro Trailer Backup Assist will default to sticker mode. Until then, if you want to use this feature, you have to mount the sensor to the trailer, and connect the wiring harness.

Hopefully the update is forthcoming soon. I have some camping and trailering to do!

Is your Airstream a conventional trailer or gooseneck? I haven't tried to mount the sensor on my conventional boat trailer only because the instructions tell me to stick on a piece of the trailer that doesn't move with the trailer. I assume the wire harness is only for gooseneck trailers....

Airstreams are only travel trailers, not goose/5th.

@dog_tired can you share some pics of your hitch setup?

It's conventional. Took it out for a test spin this morning. I can't wait to get the pro back up assist running.

I’d like to see some pics too.

@dog What wdh hitch are you using?
Wish I would have seen this earlier! We took it out this morning and I disconnected everything when we got back home. I will take pictures later this week and I'll share them.

My WD hitch is an E2 with 1000 lb round bars. IT's the same one I used on the X5, and it's a bit overkill for a 6000lb GVWR Airstream, but I have never had any issues towing with the X5 (Florida, limited hills) and it was fine this morning.

One thing I'm happy to disconnect is the Prodigy trailer brake controller, and simply use the integrated one. Got it set even before pulling out of the drive, and very smooth braking at slow and higher speeds.

I have reread the instructions and as I read it the sensor works with conventional trailers. You just place the sensor on tongue of the trailer that pivots during turn.

If it ever quits raining and turns warm I will try it.
Yeah a picture would be super helpful. I'm stuck on figuring out where the vertical part of my trailer that pivots is. I have a winch post at a 70-80 degree vertical....

I would think the placement would be on the v-frame about a foot back. The sensor is about the width of the frame.

I think youre right -- it seems to be the most logical spot. Will give it a whirl next weekend and post an update with pics. thanks!

I did a Google Scholar Search for the patent for the PTBA camera targeting system and read through it. This led me to look more closely at my particular set up. The hitch I had was an extended one, and the drop was 4" which put the angle of the tongue at a slightly downward angle taking the trailer off-level. My thinking was that maybe I pushed the target decal out of the camera range to target it. Today I picked up a shorter hitch with a 2" drop which brought the decal closer to the rear camera and perfectly level. Still doesn't go into calibration when I try to set it up with the decal option. Sorry no progress to report. The more firmly backs up my theory that it's a design flaw in the 2021 - SYNC4 and not user error. Here are some diagrams from the patent document that helped me think it through. The Patent document can be found here:

If anyone has a contact at Ford's Design Team that can address this problem it would help.
