There is a service note out there about this. You may or may not have the connectors. It's an assembly line lottery I guess.
Installing Tow/Trailer Hitch Wiring Harness
I have purchased a trailer hitch kit (FK4Z15A416A) and trailer hitch electrics kit (FK4Z15A416A) for our Transit Wagon (LWB Medium Roof) from a local Ford dealer.
I have installed the trailer hitch. I am in the process of installing the wiring harness kit. I am having trouble locating the connectors at the front and rear of the vehicle to connect the new harnesses to. From the limitted information I have, the vehicle connector should be under the van at the driver seat location and the other should be under the van at the right side rear of vehicle near the rear axle. These connectors are suppose to be branches of the the main vehicle harness that run from front to back next to the fuel tank.
Our wagon do not have the tow package or the provision. I am not sure if this kit is for vehicle with provision only. I do not see any trace of these connector at all. Is there a way to obtain the wiring diagram for the tow/trailer electrical? I greatly appreciate for any info to complete this trailer harness installation.
Thanks.

Thanks Alarmist.
I just found the Q-227R1 SVE Bulletin that confirms what you have mentioned. Our vehicle built date was 1/13/15, before the cutoff date of 1/28/15. Look like I will need the wiring diagram for the tow/trailer electrical and duplicate the missing wire runs and connectors. This is becoming a bigger task than anticipated.
Does anyone know where I can get the wiring diagram for the tow/trailer electrical? Thank you in advance.

Thank you PeterR.
I will try helminc.com.

I just looked at the Helm site, and it may be that they don't have the wiring diagram from Ford yet? If Ford dropped the ball during assembly, and did not install the correct wiring in your Transit, it might be time to ask for the correct one to be dealer-installed at Ford's expense?Thank you PeterR.

Although, as I read the SVE Bulletin you reference, it does not seem to cover your situation exactly, because you did not order any of the trailer towing packages (if I have understood you correctly). Adding after-market hitches and trailer tow wiring into a rolling computer may be more difficult than everyone assumes.
Good luck!
PS -- Edit -- You know about the BEMM? Electrical starts on p. 51 of this PDF:
https://www.fleet.ford.com/truckbbas/topics/2015/2015_Transit_BEMM_v1-0.pdf
with trailer tow items on p. 58.
PeterR, you are correct that the SVE Bulletin is not specifically for this issue. I was just using the SVE Bulletin to understand why our vehicle did not come with the tow/trailer connectors.
I will take the vehicle to the Ford dealer and ask them to install this tow/trailer electric kit. I will report back with any new info.

The Ford site indicates the wiring kit will not work on certain vehicles, the BEMM clarifies which ones. I guess it's not a lottery after all.
Could you give us a link for that please?The Ford site indicates the wiring kit will not work on certain vehicles, the BEMM clarifies which ones. I guess it's not a lottery after all.

What he said. The N in CAN is for network. Your electrical gremlins are now all politicians....Adding after-market hitches and trailer tow wiring into a rolling computer may be more difficult than everyone assumes...
I looked under our vehicle. Our vehicle has the CK4T-14406-RZF. It has one extra letter "F". Eitherway, our bad luck, no conectors.
I am planning to bring the vehicle to the Ford dealer for the tow/trailer harness installation tomorrow. I will update when I have any new info.

What do we suppose that fuel harness is? I have no current plans to add a tow setup, but, it would be good to know my prospects, if the desire arises.Here you go:

Maybe you're in luck and the F means the opposite of what vulgar individuals such as myself would interpret.I looked under our vehicle. Our vehicle has the CK4T-14406-RZF. It has one extra letter "F". Eitherway, our bad luck, no conectors.

That's vulgar. >You mean kenjent is F'd?
I guess you can say that PeterR >.
I hope for better news tomorrow when I bring my vehicle to the dealer for this install and some warranty work. I am not holding my breath though.
I might have to abandon this Ford tow/trailer wiring install and go with one of the cheaper after market trailer wiring harness.

Sorry kenjent, the door was open so wide I kinda fell through . . .
I dropped the vehicle off at dealer last Friday for the trailer harness installation. As expected, they can not install this wiring kit because of the missing connectors in the 14406 main harness. I was disappointed but did expect it.
While I was at the dealer, I spoke to the part counter lady about my problem with the wiring harness. She was able to provide me with some wiring diagram of the 2014 Transit tow/trailer circuit. She mentioned that the 2015 Transit wiring diagram is not available so she gave me the 2014. The wiring diagram did not match our vehicle exactly, but I was able to decipher the wires of the system. With the understanding of the factory wiring diagram and some of the websites for aftermarket tow/trailer equipment (etrailer, Hopkins), I was able come up with the need wiring to install this Ford tow/trailer electrics kit (FK4Z15A416A). I tested the tow/trailer 4-way connector with a LED 4-way flat tester. The LT/RT/Brake on the LED tester lights up as expected. I was not able to test the 7-way connector because I do not have the trailer brake controller install.
I have to make a 6-wires jumper harness between the new trailer module jumper connector (under the van at the driver seat location) and the tow socket jumper (under the van at the right side rear of vehicle near the rear axle). One of the six wire in my jumper harness will go all the way to the engine compartment to pick up the reverse signal per SVE Bulletin Q-227R1. The harness will be approximately 10 feet long except for the one reverse wire that will be 16 feet long. My only problem now is find the mating connectors to the kit jumper harnesses. Otherwise I will have to cut the connectors off the kit jumper harnesses and splice the wires together.
I really want to find the mating connectors but do not know where to start. Would someone have the information of how and where to get these mating connectors?

There was no full size 2014 Transit manufactured in the United States, so it is unclear what the counter lady was referring to IMO. Perhaps you got information relating to a Transit made in Europe in 2014?. . .

You also asked: "Would someone have the information of how and where to get these mating connectors?"
The answer to your last question is to go to a Ford dealer, again in my opinion.
[and yes, I realize this solution is circular . . . ]
