2015-2020 Ford F-150 Trailer Brake Controller Install Guide 

I have a 2019 F150, XTR 2.7L, basic tow package w/out trailer assist. I just used this video to install an amazon OEM controller $169: Had some trouble shooting issues: #1: the latest OBD2 was not recommended by the forscan software for this vehicle. However, it still worked, even though it couldn't read certain things. Make sure you install the latest drivers ( I had to do it twice) and run forscan a few times to get it to find my vehicle. Including restarting the computer a few times. #2: Make sure to enable ALL THREE trailer options in the IPC. THIS INCLUDES the "trailer brake module" #3 after "writing" to the PCM, it looked like my dash and gauges had a 10 second seizure. if you get a trailer "FAULT" screen after updating: check the fuse box for power to the brake controller and ensure you have a 30A fuse in slot 24. Some posts I read said to disconnect the battery for 20 minutes, obviously this wont work if you don't have a fuse in the correct slot.

Thank you for the extremely helpful video! Some of us novices don't understand all the terminology so we need to watch some parts multiple times 😊

Very helpful video! What I encountered and what eventually fixed it - When I installed my brake controller from Levittown Ford Parts, I had enabled services for all 3. I then had the brake module fault error. After searching for this error, found that most commonly associated with fuse. The fuse was missing, so I added the 30 amp fuse. No more fault, yet I wasn't able to adjust the gain even with the trailer attached. I reconnected my pc to the car computer and the brake module had been disabled! Maybe because of the fault error? I enabled it again and it works! Thanks again for your very informative and helpful video!

Very helpful. I needed to get the extended FORSCAN license but it was a free two month trial. Thank you. Saved me a lot of hassle doing it myself.

Thanks for the video. Well done and easy to follow. Took me about 45min start to finish. Looks good and works as it should.

Excellent tutorial. Took 20 min , from starting to tidying up , after getting the extended license. I’ve never used ForScan before either.

Another thanks from me for the video. Great and simple approach to it. Got it done with this being the first time I've take apart my F150 (had it 3 weeks)

Holy cow! Can't thank you enough for this video. Helped me install this so easy. And saved me a ton of money!

Thanks for the video. Clear and to the point. Just finished my install and everything looks good!

Top notch video @Shealeey! I followed you through the process on my 2020 Lariat Sport and it took me 15 minutes

This video was great! Had it all done an put back together in about a 1hr. Very easy to follow.

This video is phenomenal. Made my life 100 times easier.

Video was awesome! Made setting up my break controller a breeze! Thank you!

I've been waiting to do this for awhile and I'm glad I saved your video. Excellent job and was indispensable

Thanks for putting this video together. You saved me a ton of time and money! Really appreciate it.

Very well done and most helpful. Put my trailer brake controller in without a hitch.

Hey thanks for this video. Watched 2 others from others that did not explain things well enough and/or missed steps/ info. ✅✅✅

Thank you! Found this very useful and was able to install it successfully!

Very helpful. Buying a 2019 150 this weekend. Thanks

This was perfect. Thank you!

Thanks for your knowledge, very helpful!!!

Great Video. covers everything THANKS

Thanks man! Only took me 2 hours to set it up completely thanks to you....

Man you are a great help!!

Awesome video

Great video. Thanks.

Video was awesome

Very helpful. Thank you

Awesome video 👍

Good stuff, thanks!

Perfecto! Thank you

well i just completed in a very short time I skipped the under the steering wheel part. pop radio panel pull empty holder out unplug wires, plug in controller and put radio panel back in

I saw another video stating that on the 2015 and 16 only enable the gain? any thoughts on this?

Do I assume a wiring harness if there is a 7 pin connector?

Awesome video, mines currently wired for a 4 pin.. After doing this do I have to rewire it all for 5 or 7 pin?

Is your interior wrapped or painted? I'm looking to do the same thing! I love it

that supra in the back 😁

Is there a trailer controller that doesn't require the computer

Just installed a brake controller on 2017 f150 and now there are no lights at all when we hook to our camper. Had lights before installing the brake control. What fuses should we be checking or anything else we should check?

If you only have a 4 pin will a 7 pin adapter still function the brakes

Hello, I have a question and I hope you can help me, I have the F-150 XL 2020 with the most basic display, I have carried out all the steps, in the IPC module only one option appears to activate, I did it and everything is in order, the intensity controller works, but it doesn't appear on the screen when I increase or decrease the braking intensity, nothing appears but it does work, any suggestions? Do I have to activate something else to get the information on the screen?

Can I substitute xtools D7 OBD2 scanner for the FORSCAN tool?

Thanks for this video, just have question my truck dont have ipc configuration on forscan what i can do? I have f150 xl 2017

What should I expect when I go to add this to my 2016 F150 that has trailer back up assist and no damn center console?

Hi sr nice video, i have a cuestion , do you know how to doi it in a f250 2017 xl? I just got the control in the dash and brought the license for the forscan but on the end when i try to enable the trailer control module for exemple, just show a a message saying " failure blocks , not , compatible " thanks so mucho

If I am replacing the original brake controller in my 2015 F-150 with a new (Amazon purchased) brake controller, do I even need to do the Forscan procedure? Great video, BTW. Thanks!

what about the third option, "trailer brake module" you didn't enable that in your video, and cant find much about it online...

What do you do at the part where you cycle the key on when you have a push button start?

Thank you for the video. Question: I see Three options: Trailer brake control module, trailer brake controller gains setting, and then trailer brake module (which you didn't change, correct?). Is that last one, trailer brake module, something else? Thank you

I keep getting trailer disconnected after installing and won’t let me gain the brakes. Just says “no trailer” Any tips or help would be appreciated.

Hey heads up. The Amazon brake controller boxes are very hit or miss. I heard alot of stories about them melting and or smoking from getting hot

Hi, Do you know if I can do this to the 2021 ford f150. I just bought a new one but doesn't have the trailer brake controller. Thank you for your video

I did this upgrade a while back and just recently purchased a travel trailer. With the travel trailer, I haven’t been able to use the electric power jack or use the slide while hooked up to the truck. Would this be an issue with the truck or the trailer? I saw I have some extra harness in my truck that looks like it might plug into the trailer brake but I don’t really know what it does. Any ideas?

Good Video, simple enough to follow. I'm having a problem though with the trailer being detected. I'm getting power to the trailer and the controller will activate the brakes when i manually grab the controller lever. However the dash will say Trailer disconnected same with the Gain control. Any theories?

Very good video !

Awesome video. My dad installed a knockoff brand and now the trailer brakes are locking up when he connects it. He has purchased the correct brand. Does he have to reprogram after install? Do you know?

What’s the “Trailer Brake Module” in FORScan and why don’t you enable it as well as the Trailer Brake Control Module, and TBC Gain?

2016 F-150. Went through the install and enable process, but no luck. Subsequently realized 30A fuse in engine compartment was blown. Now I'm having another issue. I've begun experiencing a parasitic draw since installation. Based on my 'debugging' procedure, it appears that I'm dropping voltage across (cabin) fuses 12 and 13 which are for 'Climate head module, smart datalink converter, cluster, and SCCM'. Still need to verify, but my question is whether anybody else has commented on or run across anything similar? Wondering if it's a hardware thing, or possibly something to do with the forscan setup. Haven't been able to find anything elsewhere, so this is a bit of a 'shot in the dark'. Good vid. Thanks.

Just did this in record time thanks to you. However curious if you’ve seen the dash say trailer disconnected when trying to activate the brake and any time I raid or lower the gain I get that same error. Also the gain doesn’t go up on the meter when brakes are applied.

My OEM brake controller came with a 30a fuse. I have the 2016 XLT - where does that fuse go, or is it just a spare?

Can I disable the speed limiter on the "my key" setting with that forscan?

Do you have any links for a good controller from Amazon. I’d love to get a more affordable controller vs paying the full price from Ford. Thanks for a great video.

Great video, but I don't get any trailer braking when I apply pressure to the brake pedal. The trailer brakes do function properly when manually applied. Any ideas????

So the forscan program is saying “this adapter is NOT recommended for this car - some Forscan functions may not be available or not work properly.” once I switch over to MS scan it does not run the program (log) any farther. Is this error stating the forscan adapter does not work with my truck or is does it mean the brake trailer i purchased and installed isn’t compatible? I have a 2019 F-150. Any ideas?

I have a '14 Platinum with the factory controller already installed. I just found the two fuses in the glove box and plugged those in but it still says "trailer disconnected." Think I need to have the settings enabled like you did there?

Your notes advise to enable all "3" trailer control modules but you only enabled 2 with forscan? which is correct?, thanks...........

I did this and I have all my gain settings that I can adjust. When I Jack my trailer up the trailer breaks don’t work when I apply the truck break. They do however work when I slide the bar over on the trailer break controller. Any idea how to fix this?

I followed the instructions and upon completion my truck displays "trailer brake module fault" every time I start my truck. Any suggestions?

What is that 3rd module for that we don’t enable?

After doing the installation and Forscan the exact same way, I keep getting a message saying “Trailer Brake Module Fault” Any help ?

Thank you for this video. I installed exactly how you showed and same parts. And synced it with the ELM. Took me about an hour and 15. However, I tested it out today and it’s not powering through the pedal. When I hit the manual feature, it will brake. Also, when I hit the manual slide the truck says “trailer disconnected.” Not sure if this is an issue with the truck or OEM part or trailer. I would be grateful if you could give any input!

Can’t get this to work on my 2016 f150 xl when I go to use it tells me my trailer is disconnected. Does anyone know what the issue might be?

So what does the gain setting need to be set at?

How did the brake controller you got from Amazon hold up? I'm seeing a lot of bad reviews/high rate of returns. Or are those just the reviews of people who don't have a clue of what they're doing?😂

Is any shop in N. Houston able to install this?

So..I have a 2019 f150. I bought an oem controller, hooked it all up. And for the heck of it I was driving and squeezed it and it works.? Didn’t take it to the dealer to get activated yet. However, on the checklist screen the module does not show up as if it’s not there. Strange. The gain setting on the module even adjusts. Any explanation? Haha not sure if I should talk to the dealer

We can't get the key to open on our computer. Any suggestions?

Followed instructions and it seemed to work. But now my ebrake controller is using 3.5 amps in truck off position. 3.5 amps will drain a new battery in 48 hours. Is it the third line that needs to be enabled to fix this?

Enabled all 3 when stepping on brake pedal or using the slider I get a " trailer disconnected " on the dash this is with a trailer tester plugged in

So your truck already has a 7way plug?

Having issue alot of people have. Brakes only working when manually applied on the controller. Then trailer disconnected pops up. No gain showing on screen. 2019 lariat Purchased Ford part. Enabled all 3 on forscan. Anyone find a fix???

Where did you get the gauges

Do you not enable the trailer brake module?

So you don't need to enable "Trailer Brake Module"?

I got the email for the extended license key and click on download but it's not working

No need to pull the metal panel under the steering wheel, save yourself some time

Holy CRAP do they make it painful !!! Next year maybe you'll have to drop the entire engine to get access !! WOW.🙄

I am trying to help a buddy in N Houston, Tx. With his '17 f150 and I am in Atlanta, Ga. He is not very mechanical and won't tackle this. I am hoping to find a shop near 77066 to help him.
