Setting Up the Ford Integrated Trailer Brake Controller (Raptor, If Equipped)
Ford's official walkthrough covers the controller itself. Here's the Raptor-specific context: how to check you actually have it, how to set gain safely, and what changes when you tow with it.

Who this is for
This applies to any Raptor — Gen 2 or Gen 3 — if equipped with Ford's integrated trailer brake controller (TBC). If you tow with electric or electric-over-hydraulic trailer brakes and your truck has the TBC, this is the setup you need before you hook up. If you're not sure whether your truck has it, the first step below covers how to check. Trucks without the factory TBC can run an aftermarket controller instead, which is outside the scope of this write-up.
Tools
- A trailer with electric or electric-over-hydraulic brakes, wired to the truck's factory 7-pin connector
- A safe, open, low-speed area to test brake feel before you tow on the road (an empty parking lot works)
Parts
No parts required for this job.
Steps
Confirm your truck actually has the integrated TBC
Check whether your truck has the factory TBC before anything else. Look for a dedicated TBC control with plus/minus gain buttons, usually near the steering column or on the dash, and check the message center menu on the instrument cluster for a TBC settings screen. If you don't see either of those, your truck most likely doesn't have the integrated system, and you'd be looking at an aftermarket controller instead.
Connect the trailer and power up the system
Plug the trailer into the truck's factory 7-pin connector and switch the ignition on. With a trailer connected and its brakes wired correctly, the TBC should recognize the load — if the system reports no trailer detected, check the connector and the trailer's brake wiring before assuming the controller itself is at fault.
Open the TBC menu in the message center
Navigate to the trailer brake settings in the instrument cluster's message center. This is where you'll see the current gain setting and be able to adjust it, along with any trailer-type settings the system offers.
Set the gain using a real test stop, not a guess
Gain controls how aggressively the trailer's brakes respond to the truck's brake pedal. Rather than pick a number and hope, drive to an open, low-speed area, start with a lower gain setting, and make a firm brake application from around 20 mph. If you don't feel the trailer brakes contributing much, increase gain incrementally and repeat the test. If the trailer brakes feel like they're grabbing or the trailer feels like it's pushing the truck under braking, back the gain down. The right number is the one where the trailer brakes help you stop smoothly without locking up or lagging behind the truck's own brakes — and that number is different for every trailer and load, so don't carry a setting over from a different trailer without rechecking it.
Use the manual override for real-world adjustments
Most integrated controllers include a manual lever or slider that applies the trailer brakes on their own, independent of the truck's brake pedal. This is useful for settling a swaying trailer or testing brake response without touching the truck's brakes at all — get familiar with where it is and how it feels before you actually need it on the road.
Recheck gain whenever the load changes
A gain setting that felt right for an empty trailer will usually feel too aggressive once it's loaded, and vice versa. Get in the habit of doing a quick low-speed test stop any time the trailer's weight changes meaningfully, rather than assuming last trip's setting still applies.
Specs
No verified specs apply to this job — check your owner's manual for exact figures.
Safety notes
- Always test a new gain setting at low speed in an open area before towing on the road — never dial it in during normal traffic.
- A trailer brake setting that's too aggressive can cause the trailer to lock its wheels under braking; back the gain down if you feel that happen.
- A setting that's too weak leaves the truck's brakes doing more work than they should with a loaded trailer attached — don't skip the test stop just because the trailer feels light.
- Recheck the 7-pin connector and trailer wiring before blaming the controller if the system doesn't detect the trailer.
Owner questions
- How do I know if my Raptor has the factory trailer brake controller?
- Look for a dedicated TBC control with gain plus/minus buttons near the dash or steering column, and check the instrument cluster's message center for a TBC settings menu. If neither is present, your truck likely doesn't have the factory system.
- What if my Raptor doesn't have the integrated controller?
- You'd be looking at an aftermarket trailer brake controller instead, which is a separate install and outside what this guide covers.
- What's the correct gain setting?
- There isn't one correct number — it depends on your specific trailer and load. Use the low-speed test-stop method above: start low, increase gain until the trailer brakes contribute noticeably without locking up, and recheck any time the load changes.
- Is the setup the same on Gen 2 and Gen 3 Raptors?
- Functionally yes — Ford's integrated TBC works the same way across Raptor generations that have it, if equipped. Menu wording can vary slightly by model year.
- Does it work with electric-over-hydraulic trailer brakes, or only electric?
- Ford's integrated controller is designed to work with both electric and electric-over-hydraulic trailer brake systems.
