Here's a screenshot of the stuff from the BEMM book:
View attachment 152146

After some digging on the Tasca website, I managed to track down several of these parts.
This is the part from the SVE bulletin that @Michael Ophus provided. It appears to be the full kit, including the grounding plate.
JC3Z-18813-A
This is the part (one of them, at least) mentioned by @theophile. No image and no description is provided, unfortunately.
LK4Z-19A390-A
I wasn't able to find an exact match for the part listed in the BEMM that @eranrund provide. In fact, couldn't find a single part with the KK3T or KTKK3T prefix. My guess is that the prefix is merely a model designator. I found several parts for 18812 with different prefixes, but none of them were a full kit. Most of them were just cable assemblies, such as this one for the F-150.
JL3Z-18812-C

The 18813 kit seems like the best choice.

BTW, if anyone wants to do his/her own search, I recommend using the "site" search term with Google instead of the search box on the Tasca website.

That's interesting, as that kit seems to suggest the "shark fin" is only for satellite radio. I wish there were a way to know for certain what this antenna is for. Does anyione have a wiring diagram or schematic for the radio system?

 

I didn't know about this shark fin. How tall is it? Is it new for 2020? I'm also trying to fit a 2020 low roof in my garage and don't have much room to spare. I pulled my friend's 2016 into my garage but not all the way because I need to modify my garage door opener arm.

 

I didn't know about this shark fin. How tall is it? Is it new for 2020?

It is different than the previous satellite antenna and appears to be for some combination of the various antennas needed, particularly the new FordPass/modem feature.
These are random images from ford.com that show it:

 

Here's a picture I took trying to park a test-drive 2020 Transit in my garage. The roof should just clear but it looks like the shark fin will clip the trim board.

 

Try to reverse in, I'm pretty sure the rear end is higher and you don't have much clearance there!!!

 

.
Chop a bit of the board off?

Why do house builders build such low roof garages?

A lot of people drive proper trucks.
.

 

Can you measure the fin and tell me how tall it is? I'll likely do the same thing you're doing and bring one home to try.

 

I may ultimately have to modify the garage door opening if the rear of the van is taller than the front, but I presume that even so, the highest point on the horizontal plane is probably the tip of that antenna. I've got a possible aftermarket solution but I need to verify a couple of things. I realize that this antenna is new for 2020 so this may be an "emerging issue," but maybe there are some Ford electrical engineers on here who might be able to weigh in?

Anyway, here is an aftermarket rooftop low-profile antenna for GSM/CDMA cellular service. It's got two leads, each with SMA connectors. The stock shark fin also has two leads coming off it, with a double fakra connector:

It's not the best picture, but based on the color of the connector and what I can tell from zooming in on it, it looks like the "bottom" prong is the fakra "C" form factor:

According to the chart below (which I found on ebay, so take that for what it's worth) the fakra C connector in US vehicles is typically used for GPS telematics or in a "multi way application" combining GPS and GSM signals:

That seems consistent with the notion that this shark fin is a combined GPS and GSM antenna, and that one of the two leads may simply be "dead" wiring in a vehicle without GPS functionality.

So, assuming all of this is correct, I am thinking that I could buy this aftermarket GSM antenna, get a Fakra "Z" (universal) to SMA adapter, and essentially make a low-profile replacement part that connects to the factory wiring on the prong that carries the GSM signal, leaving the GPS prong empty.

Is anyone sufficiently familiar with the 2020 electrical system that they could confirm or correct this? Also, does anyone happen to have the shark fin remove/replace procedure from the shop manual? Thanks in advance!

 

The link by MO above (Post #2 ) says it can be relocated, maybe that's the best option.
The one on mine is a like a raised disk (hockey puck) no edges like the new fins.

Semper Fi

 

I'm hesitant to do anything that would require drilling new holes in the body, especially since I'd still have to cover the hole at the stock mounting point anyway. I think there's a good aftermarket solution, assuming I can get confirmation of the part number/function, and ideally a pinout. Is this information available yet?

 

Thanks to your post, I checked out a 2020 transit from the dealership today to see if it would fit. The shark fin doesn’t touch the weather stripping but it’s close. I think the front slope of the van helps. The dealership suggesting swapping it with the mustang antenna which is very low. Or maybe there’s an antenna from another Ford model that would work? You could even get the paint color to match. Could work but please know that I know way less than you do.

 

I'm going to call the parts department of my local dealership tomorrow and see if they can confirm the part number. Nobody seems to have it, and the part number I posted earlier is from the 18-19 Expedition. I think it's the same part but not certain. I'll also ask the service department if they have the wiring diagram or connector pinouts.

The Mustang GPS antenna only has one lead, which is what makes me think the shark fin version is doing double duty as a GSM antenna too. Somebody knows the answer, I just have to find them...

 

Perhaps the photo angle is different but it appears that a 10" wide area of that trim could be removed along with increasing the 'raise' travel limit on the door to above the curve in the track so the leading edge of the door travels another seven or eight inches further in the track - - And perhaps remove a portion of the bottom stiffener on the door - - Good Luck - -

 

theophile,

Another option that hasn't been mentioned here for awhile, maybe get some air bladder shocks for the front. Lower the front end going in and raising it back up when you exit.

Semper Fi

 

Or just add some weight if you're planning to put stuff in it later. Just remember to tell the kids not to bounce when you're going into the garage.

 

.
If you don’t have kids, round up some fat neighbours.

This in a way makes me happy I decided to upgrade from my current LR to the MR. I would have been pissed if I got the LR and couldn't fit it in my garage because of the fin. What a waste of height on Fords pars.

 

I don't think it's new as my 2017 has it.

Possibly just remove the trim board altogether as it serves no purpose. Is this a double garage w/ one door? If not, then the opener arm is probably going to hit.

 

Sorry for the delay. I went by the parts department of my local dealership and got a more accurate part number. The 2020 Transit part number begins with "LK4Z-19A390-" and then the suffix seems to depend on the vehicle VIN or options. There are three that appear to apply to the low-roof model:

p/n LK4Z-19A390-A applies to:

• 10/21/2019, Transit V363, All Reg/Ext Vans/Wagons & Cutaway, With Low Roof, ICE- Low Audio (0C), Cellphone Interface System - 4
• 10/21/2019, Transit V363, All Reg/Ext Vans/Wagons & Cutaway, With Low Roof, ICE - Mid Audio W/BVC, Cellphone Interface System - 4

p/n LK4Z-19A390-FL applies to:

• Primed, 10/21/2019, Transit V363, Bus (M2), With Low Roof, ICE - Mid Audio W/BVC, Cellphone Interface System - 4
• Primed, 10/21/2019, Transit V363, Bus (M2), With Low Roof, ICE- Low Audio (0C), Cellphone Interface System - 4

p/n LK4Z-19A390-EL applies to:

• Primed, 10/21/2019, Transit V363, Bus (M2), With Low Roof, Cellphone Interface System - 4, Low Level Audio 2

Unfortunately, the dealership didn't have any of these in stock so I couldn't look at them or take photos of the connectors. I can't find any photos online either. I'm also not sure from the above application descriptions whether the different part numbers actually function differently, or if they are purely cosmetic differences (such as painted vs. primed).

Along these lines, does anyone know what the abbreviations "ICE" and "BVC" mean? Maybe "bluetooth voice control" for the second? And what are "low audio" and "mid audio"? There also appears to be a distinction between "Low Audio (0C)" and "Low Level Audio 2." Anyone know what that's about? Finally, does anyone happen to have access to any of the above three part numbers such that you could post some photos of the connector(s)? Thanks!

 

Eight months later... Did you come up with a solution? Did you figure out the two connectors and associated signals? I'll be tackling this problem soon myself and would really appreciate any feedback you can offer. Thanks!

 

Unfortunately I never did get to the bottom of things. I had planned to get the aftermarket short antenna and then just experiment with the connections, but when my Transit came in, I found that it did in fact just barely clear the garage door.

 

Running into a problem with this antenna as well in my 2021 high roof. I want to place a roof rack and it's in the way. The 2020 BEMM mentions a relocation kit but googling those part numbers shows no result - does anyone know what thats about? I am not sure that the relocation kit mentioned above in this thread is compatible - GSM/GPS might be a different connector/antenna than the satellite radio one.
Here's a screenshot of the stuff from the BEMM book:

Some thought that I've had regarding this - I am planning on having a WeBoost or similar signal booster. I wonder if in that case I could relocate the existing antenna inside the van?

Figuring out how to properly seal the roof hole is another challenge...

 

See Post #2, The photo shows some other ford truck but this is for the Transit too.

 

drop your tire pressures....

 

Hi there!
I also have a WeBoost I am planning to install.
Did you end up moving the shark fin inside? elsewhere outside?
how did you seal the hole?
thx!!

It's been four or five years, so previous posters have presumably figured out that the shark fin antenna is NOT the highest point on the roof of their vans--the rear roof is. At least, mine scraped the standard-height garage door trim the day I brought it home from the dealer, while my shark fin has always cleared with ease. I removed that useless piece of trim and ever since I've had a full 3/8 inch clearance to spare.

Watch out for ice and snow buildup just outside your garage door, which will also cause clearance problems. Don't buy larger tires, including snow tires with their deeper treads. If you buy used, bear in mind that your tires may be worn enough to lower the van by about a half-inch. And be sure all nails and screws in your trim are fully sunk (ask me how I know this).

Hope that helps someone stumbling across this thread.
