cermep auto Electronic Proportional Trailer Brake Controller 90885 — LED Display, Adjustable Boost

The cermep auto 90885 is an electronic proportional trailer brake controller that senses your vehicle’s deceleration and applies trailer braking force automatically for smoother, safer stops.

Whether you tow a small utility trailer or a multi-axle camper, the 90885 installs into most 12V towing systems and provides proportional braking that mirrors your tow vehicle’s slowdown. Designed for compatibility with a wide range of domestic and import trucks and SUVs, this unit offers a digital readout, manual override, adjustable boost levels, and internal protection circuits for reliable on-road performance.

How does the 90885 create smoother stops when towing?

The controller uses an internal inertia sensor to detect the exact rate at which your tow vehicle decelerates, then applies matching braking power to the trailer. This proportional approach reduces jerking and improves stability compared with time-based controllers.

• Internal G-sensor for real-time deceleration sensing
• Automatically scales brake force to match vehicle slowdown
• Reduces abrupt trailer movement during emergency braking
• Adjustable boost for heavier loads or contested stopping

Will this unit work with my truck or trailer setup?

The 90885 supports trailers with 2, 4, 6, or 8 electric brakes and is compatible with common trucks and SUVs from Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep. Note that the vehicle-specific plug-and-play harness is not included, so verify connector type and wiring before purchase.

• Works with 2–8 brake electric trailer assemblies
• Compatible with many factory tow packages on popular brands
• Requires proper wiring harness or hardwiring for installation
• Cross-compatible with controllers like Tekonsha Prodigy P2 in function

What controls and feedback does the driver get?

A clear LED display shows real-time settings and voltage output so you can confirm the controller’s status at a glance. A manual override slider permits immediate trailer braking independent of vehicle deceleration, and multi-level boost provides extra stopping force when hauling heavier cargo.

• Digital LED readout for brake power and volts
• Manual override slider for instant braking control
• Multi-level boost to increase trailer braking as needed
• Diagnostic indicators to help troubleshoot wiring or output

How durable and safe is the 90885 in everyday use?

The controller is built into a rugged housing and includes advanced internal circuit protection to guard against short circuits and voltage spikes. Those safeguards protect both the unit and your vehicle’s electrical system, and the product is backed by lifetime after-sales support.

• Sturdy enclosure designed for automotive environments
• Built-in surge and short-circuit protection circuitry
• Stable connection design to resist vibration and wear
• Lifetime support, warranty, and return service available

Who is this for: The cermep auto 90885 is aimed at drivers who tow regularly and want a dependable, proportional braking solution without proprietary vehicle-only restrictions. It suits owner-operators, weekend campers, landscapers, and anyone hauling trailers with electric brakes who values smoother stops, clear diagnostics, and extra stopping power when hauling heavier loads. Ensure you have the correct wiring or purchase a compatible harness for your vehicle make and model before installation.
