I have been searching for a brake controller connecting wire for my new truck so I can hook up my Prodegy 3 controller and guess what.....I can't. I have to buy an OEM controller and have it flashed to the computer$400.When I looked online there were so many conflicting fitments so I called the dealership. The truck came with a hitch and a 4/7 pin connector soooo you would think if you HAD to have THEIR controller it would already be there.I bought one off the lot in January so I did not spec it but come on Ford...really?? Am I right in thinking if it has a 7 pin it should already have the controller as part of that package...or am I just becoming a cranky old man?

Bean counters counting beans, everywhere they can shave off a 1/4 inch of wiring. I would have to ask, did you check and see if there's a brake switch wire to tap into to activate the after market brake controller? The others are just +, - and the blue wire to the back 7 pin receptacle.

maybe this will help:etrailer support

Fisherman, I did not crawl under the dash (I was looking for a starting point).I checked on line to see what the plug end might look like but ran into so much conflicting information. The tekonsha website says there is no harness,Ford says there is no harness available yet the e-trailer website(referenced by enblethen) says"it's right here and shows a picture. The picture they reference is not that of a 2022. Sooo there is my confusion. In the end I have made an appointment to have one installed and are going to use "points" to help soften the blow.If nothing else I want to warn those who are buying a truck without a factory controller that they will need one and can't just plug one they have in.

Well, if it's true that there is no plug n play harness for an aftermarket controller, then see if there is a physical brake light switch on the brake pedal arm. If there is, you're in luck, just have to do it old school and wire up the +, -, trigger (wire to brake switch) and brake lead to light connector in back.While it seems silly, I can see this happening, as "most" trucks seem to come with a factory brake controller for several years now.

2022 F-150 Can Not install aftermarket brake controller!!!!!

To your point, a new truck, if it didn't come with a pig tail to wire onto a brake controller to plug into the truck harness, you're probably correct in it not being plug n play for aftermarket controllers.
Again, if it has a simple, physical brake light switch (which idk anymore, could be integrated into the system somewhere), it's not difficult, just more time consuming to hard wire in your own controller.

You want the Ford controller, the reason they have to flash the PCM is because of the anti-sway software. The computer uses input from all suspension and powertrain sensors to detect sway and apply the TT brakes as needed, something you will never get with an aftermarket unit, as good as the P3 is.

I agree you would think if you have the trailer connector it would have the controller...maybe the chip shortage played a factor and it got shipped without it? At any rate, with the $$ you have wrapped up in that new truck, spend a few $$ extra to get the Ford controller and have it programmed in, you will never gat the level of performance otherwise. Write the check and enjoy your new truck!

Side note, did you see the video posted here of another forum member taking his 7200 lb TT up Monteagle grade in TN with his little 2.7? Really impressive performance! Hard to say, but it pulled better than my old Suburban with the 8.1L!

NEVER been too impressed with the P2 or P3. OE is MUCH better.

At least my money will be well spent. Thanks for all the input.

On my '19 F150 if you pull off the filler plate on the dash you should find a plug waiting for the OEM controller. Get an adapter and you can use your P3.

I like my OEM controller much better than the aftermarket

I had the same surprise…21 F350 and no brake controller, but I can tow a 18,000 lb trailer… just can’t stop it. Dealer wanted $200 for controller & $50 to install. Bought a $30 one on EBay and had dealer install for $50.
Your truck should have come with a pigtail to use your P3. Getting to the plug requires pulling the dash apart, not that hard once you watch a video.
