10 Best Electric Brake Controllers 2025 in the United States

The REESE Towpower 8507111 Brakeman IV is a time-delay brake controller suitable for a wide range of towing vehicles, including popular brands like Ford, GM, and Toyota. It supports trailers with 1 to 4 axles, making it versatile for different towing needs. One of its main strengths is the ease of installation, thanks to its Plug & Play connection and compact design, which can be mounted above or below the dash.

The time-delay feature ramps up braking power at a fixed rate, which is ideal for basic towing requirements but may not offer the precision of more advanced proportional controllers. The LED light display is a helpful feature, providing a clear visual indication of trailer connectivity and power output by changing colors. Manual braking can be easily applied using the control lever, giving drivers more control in critical situations.

The time-delay mechanism might not be suitable for those needing more adaptive braking responses, especially in varied terrain or heavy-duty towing scenarios. The product offers a good balance of simplicity, ease of use, and essential features, although it might not meet the needs of users requiring more sophisticated braking control.

The Tekonsha 90160 Primus IQ is a proportional brake controller ideal for trailers with 1 to 3 axles. This means it adjusts the braking power in proportion to the vehicle's braking, offering smoother and safer stops. It features a Plug-N-Play port for easy connection with 2-plug adapters, although it's worth noting that a T-connector, which is essential for installation, is sold separately.

The installation is made simpler with the included snap-in dash mounting clip and hardware, but some users may still find it somewhat complex if they're not familiar with vehicle wiring. The digital LED readout is a useful feature, providing clear diagnostic information and illuminating when issues occur. Additionally, the controller works proportionally in reverse, which is a handy feature when maneuvering a trailer.

The Boost feature is another plus, allowing for increased initial braking power when needed, which can be particularly useful in heavy braking situations. However, users should be aware that the product has been available since 2007, so while it is trusted and popular, it might lack some of the newer technological advancements found in more recent models. The controller's universal fit and smooth exterior design add to its appeal, making it a good choice for a wide range of vehicles and setups. The Tekonsha 90160 Primus IQ is a reliable and user-friendly option for those looking to enhance their trailer braking system, though it may require an additional purchase for full installation.
