The 90885 offers a strong feature set for drivers who want more control and visibility from their trailer brake controller. Its diagnostics and removable design are convenient, but the missing vehicle-specific harness should be included in installation planning.
How We Picked the Best Trailer Brake Controllers
We focused on the features that matter most during real-world towing: braking response, compatibility, installation, adjustment range, display visibility, and safety protections. The selection includes proportional controllers that respond to the tow vehicle’s braking force, as well as time-delay models that apply a preset braking level. We also included a wireless Bluetooth option for drivers who want to minimize permanent cabin wiring.
Axle coverage was another important factor. Some controllers are designed for one- or two-axle trailers, while others support up to four axles and eight brakes. Because towing setups vary widely, the best choice depends on matching the controller to both your vehicle’s electrical system and the trailer’s brake configuration.
Quick Comparison
- Best overall style for smooth braking: Proportional controllers such as the REDARC, CURT TriFlex, briidea proportional, and 90885 models.
- Best for minimal wiring: The CURT Echo Bluetooth controller, which uses a 7-way connection and mobile-device controls.
- Best for straightforward adjustment: Time-delay models such as the CURT Venturer, CURT Discovery, and briidea time-delay controller.
- Best for larger trailer setups: Controllers rated for up to four axles and eight brakes.
Key Buying Factors for Trailer Brake Controllers
Proportional Vs. Time-Delay Braking
Proportional controllers sense how strongly the tow vehicle is braking and apply a corresponding amount of trailer braking. This usually produces smoother stops and reduces abrupt trailer tugging. Time-delay controllers apply braking according to a preset setting, making them simpler and often less expensive, but they may require more adjustment for different loads and road conditions.
Axle and Brake Capacity
Confirm the controller’s rated trailer capacity before buying. A controller intended for one to two axles may not be suitable for a four-axle trailer. Check the trailer’s number of electric brakes, not just its overall size, and leave no uncertainty about compatibility.
Installation and Controls
Plug-and-play models can simplify installation when your vehicle has the correct wiring harness. Traditional in-cab units require a convenient mounting location and may need additional wiring. Wireless or Bluetooth designs reduce dashboard hardware but depend on a compatible 7-way connector, a charged phone, and reliable app operation.
Adjustment, Display, and Safety
Look for accessible gain and boost controls, a readable display, and alerts for wiring faults, overloads, or short circuits. A controller should be easy to adjust while parked and easy to monitor without distracting the driver.
Who Should Buy Which Trailer Brake Controllers?
Choose a proportional model if you tow frequently, carry changing loads, or want the most natural braking feel. A time-delay controller is a practical choice for occasional towing, simple setups, or buyers who prefer a predictable manual adjustment. Choose a Bluetooth unit when a clean installation and portable controls matter most. For multi-axle trailers, prioritize a model explicitly rated for the trailer’s total brake count rather than choosing based on price alone.
