cermep auto Trailer Brake Controller replacement for 1-3 axle trailers — proportional braking, diagnostics

cermep auto's trailer brake controller replacement for Tekonsha 90160 delivers proportional braking control and diagnostics for 1–3 axle electric-brake trailers.

If you tow trailers with electric brakes, this direct-replacement controller restores proportional brake modulation, easy manual override, and a clear diagnostic readout. Built to match the Tekonsha 90160 Primus IQ footprint, the unit accepts 2-, 4- or 6-brake trailer loads and offers multiple mounting choices so you can position it for convenient access in most trucks and SUVs. Note that vehicle-specific plug-and-play harnesses are not included; hardwiring or purchasing the correct harness separately may be required.

How does this controller improve towing safety?

The controller senses vehicle deceleration and applies trailer braking in proportion to the tow vehicle’s braking force, giving smoother stops and reducing trailer sway or jerking. A built-in inertia sensor and advanced circuit protection work continuously to adapt braking across different speeds and loads.

• Proportional braking via inertia sensor for coordinated stops
• Advanced circuit protection to prevent electrical faults
• Manual lever override for immediate additional trailer braking
• Real-time self-diagnostics to detect connection or performance issues

Will it fit my vehicle and trailer setup?

This replacement is designed as a drop-in alternative to the Tekonsha 90160 Primus IQ and supports trailers with one to three axles (2, 4 or 6 brakes). Compatibility depends on your vehicle’s brake controller harness—many Ford, Chevy, Dodge/RAM, Toyota, Jeep and GM models are compatible when paired with the correct plug harness.

• Fits trailers with 2-, 4- or 6-brake configurations
• Compatible with a broad range of OEM wiring harnesses (harness sold separately)
• Matches Tekonsha 90160 mounting footprint for easier replacement
• Hardwiring is an option if a vehicle-specific connector is unavailable

How easy is installation and everyday adjustment?

The unit includes both a snap-in clip and an adjustable bracket that rotates up to 180°, so you can choose a tidy, ergonomic location on the dash or under it. A manual control lever provides instant fine-tuning of trailer brake force, letting you adapt quickly to loaded vs. empty towing or changing road conditions.

• Snap-in clip for quick mounting or adjustable 180° bracket for custom positioning
• Manual lever for immediate braking adjustments while driving
• Clear digital display shows settings and connection status at a glance
• Self-diagnostic feedback helps simplify troubleshooting during installation

What diagnostic and reliability features are included?

The controller offers a readable digital display that shows current brake gain and connection integrity, plus ongoing self-tests that alert you to wiring or performance issues. Designed with robust connectors and circuit safeguards, it aims to sustain reliable operation under typical towing use.

• Real-time diagnostics on a clear digital screen
• Continuous self-checks to flag faults early
• Durable connection design to resist vibration and corrosion
• Lifetime after-sales support including warranty and return services

Who is this for? This cermep auto replacement controller is intended for drivers who tow small to medium electric-brake trailers and need proportional braking performance comparable to a Tekonsha 90160 Primus IQ. It’s a practical choice for truck and SUV owners who want easy mounting options, immediate manual control, and on-board diagnostics but may need to purchase a vehicle-specific harness separately or have the unit hardwired by a technician.
