---|---|---|---|
Simple, rotary knobAll trailer brake settings and conditions are communicated through the simple but powerful rotary knob of the Spectrum trailer brake controller. It provides highly responsive operation without cluttering up the look of your vehicle’s dash. |
Ramp-up LED displayThe Spectrum brake controller displays all settings, preferences and operations through 10 tri-color LED lights. Encircling the knob control, the lights flash, ramp up and change color based on the various braking conditions and user input. |
Two mounting optionsThe rotary knob can be mounted onto the dash for a completely integrated look with the vehicle’s other controls. Each brake controller comes with hardware for a drill mount, as well as an adhesive pad for a surface, stick-on mount. |
Out-of-sight moduleThe main module that controls and operates the trailer brakes is separate from the rotary knob, allowing you to mount it out of sight. This promotes a factory look and feel in the interior of your vehicle, unlike most other aftermarket brake controllers. |
Vehicle-specific installation
Spectrum installs easily with a CURT quick plug brake control harness. Each wiring harness is made vehicle-specific for a custom fit on each unique make and model.
Smart brake controller operation
|
|
|
---|---|---|
Highly responsiveThe Spectrum electric trailer brake controller not only has a subtle, integrated design, but it also provides intelligent, responsive braking. It uses an advanced accelerometer circuit to measure the inertia of the vehicle on three separate planes. It is able to sense the motion of the vehicle and trailer while braking, to provide proportional power for a smooth, safe stop. |
Manual overrideThe Spectrum brake controller also gives the driver advanced control over the vehicle-trailer combination, providing an easily accessible manual override. The rotary knob itself has a built-in push-button feature that manually applies the trailer brakes whenever needed to maintain full control over the towing setup. |
Automatic levelingWith its smart braking operation, the Spectrum is easy to set up for any towing scenario, including a diverse combination of vehicles and trailers. It features an automatic leveling system and automatic calibration to eliminate time-consuming requirements during the setup process. It is able to operate two to eight trailer brakes at a time, making it a perfect fit for most vehicle-trailer combinations. |
Product Description
The CURT Spectrum trailer brake controller provides powerful brake operation while maintaining a clean, consistent OE look and feel on the dash of your vehicle. It is comprised of a main module and a separate user interface. This interface is a simple rotary knob with a push-button and ten tri-color LEDs to control and monitor all trailer brake activity. It also features a triple-axis accelerometer for highly responsive, smooth stops on any grade. The separated module and interface of the Spectrum brake controller allow it to integrate with the vehicle unlike any other. The main module can be mounted behind the dash and completely out of sight. The separate rotary knob provides a sleek, subtle interface that mounts on the dash of the vehicle wherever desired. It features ten LEDs with three colors each (red, green and blue) to indicate trailer brake activity and power adjustment. The rotary knob and integrated push-button allow for simple and effective operation of the control settings and manual adjustment. The Spectrum trailer brake controller offers superior safety and helps protect the life of your vehicle and trailer with its advanced triple-axis accelerometer. This integrated circuit detects the motion of the vehicle and trailer when making stops and applies the precise amount of brake power for maximum efficiency and effectiveness. The three axes of the circuit also enable the brake control to compensate when going up or down a hill. Like most CURT brake controllers, the Spectrum installs using one of our vehicle-specific quick plug harnesses. It also has automated leveling and calibration capabilities to simplify and speed up the installation process. The Spectrum trailer brake controller comes with mounting hardware for a complete installation.

Reviewed in the United States on February 16, 2021
I gave it 2 stars just because I like the idea of it, but 2 stars is definitely over rated for it. The first problem I had is it wouldn’t adjust, I could push the knob in 10 times and out of those 10 times it would let me adjust the dial maybe once, and even then I’m not sure what or if it was adjusting because it seemed to make no differences in anything. I thought I’d just limp it along driving 2600 miles by manually pushing it in to activate my trailer brakes every time I needed to stop but you can’t do that either, if the foot brakes on your truck are being pressed the manual engagement of the brake controller doesn’t work, why would they do that? It must of made sense to someone who had no sense.
Then as we were coming down a steep grade on I80 in Salt Lake my wife who was following called me on the radio and said the trailer tires were smoking. I looked down at the brake controller knob and all the red lights were lit even though I wasn’t even pressing my brake pedal, it had locked itself up and was holding my brakes with full force.
There’s also no way to test this thing to insure its even working! Before leaving I installed and adjusted all new trailer brake hubs and bearings. With the wheel jacked up I spun the trailer tire and had my wife hit the brake pedal, nothing. I called Curt tech support thinking they weren’t working and he said this was how they are, they have to sense the truck is moving to work and there is no way to test them, another design element that made sense to the same person who had no sense.
Wish I would have seen this sooner, but when I was trying to find troubleshooting information there was a tech support article on etrailer that said Curt’s brake controllers are notorious for internal electronic problems, they were absolutely right. I had it too long before getting a chance to use it and find out it didn’t work to return it so now I’m stuck with a nice looking very expensive controller that’s absolute junk.

Easy to connect, set up and adjust. For a first time trailer owner I'm very pleased with this product.
