You can stick the control knob to the dashboard, plug in the module, and your brake controller installation is done with no drilling and no hardwiring. The knob is large and easy to use, while the main unit is out of sight behind the dash.

Specs:
The Spectrum puts control of your trailer's brakes at your fingertips and, with bright LED indicators, you know what your brake controller is doing at a glance.
You can adjust all of your settings using the control knob. To switch between modes, press the control button in the center of the knob. Each mode has its own distinct LED display with several different colors and patterns to eliminate any guesswork as you cycle through.
Output: Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. You want to set the braking output as high as you can without locking up the brakes.
Sensitivity: This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the set output level. This is a great adjustment to make when you're towing a heavy load and the trailer will need more umph to bring it to a stop so it doesn't push your vehicle forward. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, lower the setting. You may also need to adjust the sensitivity based on your own preferences, or when the trailer load or road conditions change.
Manual Override: The Curt Spectrum keeps the manual override within easy reach. The manual override functions as time-based for a slow reduction in trailer braking, great for stopping sway or controlling your trailer's momentum in an emergency. To engage the manual override, just press and hold the button on the control knob. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.
The Curt Spectrum comes in 2 pieces: the main unit and the control knob. Because the only part that you need to be able to access is the control knob, the main unit can be mounted out of sight and out of the way. You don't have to worry about banging your knee on a bulky brake controller or interfering with your vehicle's lower airbags.
The dash-mounted control knob can be installed in any convenient spot that's easy for you to see and reach. This can be a blank switch panel, an open spot on your center console, or wherever there's space on your dashboard. The knob sits flush against the dash, so you don't have to worry about finding enough clearance behind the dash. You can use either the included screw to mount the knob, or the adhesive pad for a drill-free installation.
Once you've decided where you want to put the control knob, you'll need to find a good place to install the main unit. Your only restriction is the 4' plug-in cable that has to be able to reach between the main unit and the control knob. Thanks to the 3-axis accelerometer, the main unit can be positioned at any angle or position. No matter how you install it, the unit will sense the direction of travel and its orientation.
If your vehicle already has a plug-in brake controller wiring harness, just connect the main control module to it. Otherwise, you will need to purchase a vehicle-specific wiring harness (sold separately) to plug into. If a harness is unavailable for your vehicle, hardwiring will be necessary.
If you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately.
Note: If a custom brake control wiring adapter is not available for your vehicle, a 30-amp circuit breaker (sold separately) may be required for installation.
Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.
The Spectrum uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to ensure that your trailer slows at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Martha was excellent to work with!
A wonderful customer experience. Worked with professionals who guided me in selecting the correct product. Thank You!
Brittany was professional and patient not to mention helpful.
Excellent service
Great shopping experience and quick del ivery.
Only ised a short time and it worked as advertised.
Small form factor works great
Installation was easy, really liked the tape option to try out different placements before drilling for a permanent mount.
Extremely easy to install. Works great!
Install was a breeze because of the vehicle specific pigtail, etrailer's customer service is excellent and the information on installation helped me locate my plug
They were very helpful on the phone to make sure i purchased the correct setup for my truck. I received it that week and installed it over the weekend. So far it is out performing the previous brake that was installed.
As far as activating trailer brakes, it works. The dark mounted knob is too large and cheaply made. I wish I’d purchased something else. Had to pull a trailer, so couldn’t send it back.
