Kolasina Proportional Trailer Brake Controller 90160 — 1–3 Axle, LED Display & Manual Override

The Kolasina 90160 is a proportional trailer brake controller that automatically matches trailer braking to vehicle deceleration for smoother, more controlled stops.

This compact, vehicle-mounted controller uses proportional braking technology to sense tow vehicle deceleration and apply the appropriate amount of trailer brake force. Designed as a direct fit replacement for the Tekonsha 90160 Primus IQ style controllers, the Kolasina 90160 supports trailers with 2, 4, or 6 electric brakes and provides a clear LED readout, manual override, and diagnostic alerts to keep towing operations transparent and adjustable.

How does the Kolasina 90160 adapt braking to different trailers?

The unit senses the tow vehicle’s braking intensity and proportionally applies trailer braking so the trailer slows in concert with the vehicle. This reduces jerking and uneven stops when hauling loads of different weights.

• Proportional sensing matches brake output to vehicle deceleration in real time.
• Works with trailers using 2, 4, or 6 electric brakes.
• Manual slider override for instant additional braking when needed.
• Stable braking across light utility and heavier commercial trailers.

What information does the display provide and how does diagnostics work?

The controller features a high-contrast LED digital display that shows braking level and connection status so you can verify operation at a glance. Continuous self-diagnostics check the system and display alerts if an irregularity is detected, helping you find issues before they become hazards.

• LED screen shows active brake output and connection state.
• Real-time alerts for wiring faults or abnormal brake loads.
• Quick visual feedback during hookup and while driving.
• Reduces time spent troubleshooting trailer brake problems.

How easy is installation and daily use in different vehicles?

Installation is designed to be flexible: the Kolasina 90160 includes a snap-on quick-release bracket plus a screw-in bracket and rotates horizontally or vertically within a 180° range to suit any cockpit layout. Note that vehicle-specific plug-and-play harnesses are not included, so prepare for a hardwire connection or purchase the proper harness for your make and model.

• Includes snap-on quick-release and screw-in mounting options.
• 180° rotation to position the display for driver visibility.
• Compatible with many Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep installations.
• Requires vehicle harness or hardwiring; harness sold separately.

What manual controls are available for on-road adjustments?

Beyond automatic proportional control, the unit provides a manual slider that lets drivers add instant braking power to the trailer—useful for downshifts, emergency stops, or handling heavy loads. The manual control is easy to reach and provides immediate feedback on the LED screen.

• Manual slider for quick, on-demand brake application.
• Immediate adjustment without changing automatic settings.
• Visible output level on the LED display while using manual override.
• Helps manage trailer sway or abrupt slowing scenarios.

Who is this for: The Kolasina 90160 is aimed at drivers who tow regularly and want a reliable, configurable brake controller that pairs proportional performance with a clear diagnostic display. It suits owners of light utility trailers up to heavier trailers with multiple axles who need improved coordination between vehicle and trailer braking, plus users replacing a Tekonsha 90160-style controller who want a compatible alternative with adjustable mounting and a two-year warranty.
