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.

    • Awesome Brake Controller
Review Image by T. Howard T. Howard
This is an awesome brake controller. Works perfect. Manufacturer VERY helpful when called and asked a question about the wiring connection. Installation is straight forward, and it looks like it was factory installed.

I was looking for a brake controller that didnt get in the way of my knees, old style brake controllers always annoyed me and just plain look bad, so when i found out about this brake controller from curt that only shows a remote knob, i figured i would try it, it is very expensive compared to other brake controllers, but its kinda a specialty for people like me who dont like normal brake controllers, so i was willing to spend the money, first off ill say everyone that had problems with the controller flashing when not in use almost made me not buy it, but i figured i would wire a on/off switch if i had that problem but it never happened to mine, I havent actually hauled a trailer yet, but i did connect to one just to see what happens, nothing different than when not connected, except when i unplugged the trailer i did get the flashing blue lights which mean the trailer was disconnected, those lasted about 10 seconds and then it returned to the normal mode, for my fellow 07-13 silverado owners thinking about buying this, just make sure you order the wiring harness adapter, its like $8 you wire it up to your trucks already pre existing brake controller wires under the dash and then it plugs directly into the module that comes with the brake controller, and then connect the 2 wires to the fuse box under the dash, they are already there from the factory, google should make all that easy, but overrall its super simple to install and super easy to use, i should be hauling a trailer soon, if this is the last you hear from me about this brake controller it means it worked great, if it does not work great i will be back to change my review ... show more

    • Best controller out there!
Best controller I've used in the last 30 years. I've owned allot of brake controllers from every price point out there and this is the best. I set it up the first time, tweaked it once and haven't touched it in almost a thousand miles. No fiddling trying to get a better stop or working out the lurches of the trailer stopping you. I can ease to a stop or punch the brakes hard, and I get the right amount of braking every time without adjusting it again. It looks OEM in the truck and the brightness is plenty adjustable, this coming from someone who will turn his dash lights off to avoid distraction. It does it's thing and I just drive. ... show more

    • Like the compact size and fairly easy to install. Decent value for the $.
Like the compact size and fairly easy to install. Decent value for the $. Functions mostly as expected with one small quirk. It sometimes has random lights lit. When I contacted the manufacturer they said this was typical and not a sign of a defect. Used for a couple years in my Jeep Wrangler before selling the vehicle. ... show more

    • Controller works, remote mouting is a nice feature, but....
It seems to work okay but the LED often stays lit, even if the vehicle is off. I found it quite annoying that, after braking, some LED's would stay lit. When this occurred, it wasn't always the same LED location or color but completely random. Often, a quick tap to the brake pedal would make it go off, until the next time I actually braked. Then, repeat the process. During the day, it wasn't awful but at night the LED's are very bright and very distracting. This issue occured whether or not I was towing, it was constant. Additionally, this was consistant between both vehicles I installed it in. The biggest issue i experienced is that the LED's would stay lit after i turned the vehicle off. So, you guessed it, my battery drained after I got out and the vehicle wouldn't start. I eventually contacted CURT customer support and they responded "this is a known issue with this model...". This is completly unacceptable to me so, i am replacing this unit and am done with CURT products. ... show more

    • CURT provided excellent technical support addressing some minor installation problems.
I installed the CURT spectrum trailer brake controller in my 2023 GMC 2500 Siera. The controller was easy to install, looks and works great. The Installation problem was simply a blown fuse in the vehicle fuse box.
