Inertia-based vs. time-based
|
|
|
---|---|---|
Two types of brake controllers:CURT electric brake controllers fall into one of two categories: inertia-based or time-based. These refer to the method of activation used by the brake controller. Both types are safe and effective for stopping a trailer. However, depending on your needs, one may be preferred over the other. |
Inertia-basedInertia-based or proportional trailer brake controllers use an electronic mechanism, called an accelerometer, to detect the momentum of the vehicle-trailer combination while braking. The controller accentuates the trailer brakes in proportion to the momentum, allowing for a smooth, highly efficient stop. |
Time-basedTime-based activation is less complex than inertia-based. When stopping, a time-based brake controller accentuates the trailer brakes based on whatever gain setting is input by the driver. Although simple in operation, time-based trailer brake controllers are effective and provide a more budget-friendly option. |
How to select a trailer brake controller
|
|
|
|
---|---|---|---|
Heavy-duty towingIf you are towing a heavy trailer or cargo, an inertia-based brake controller will provide superior control to make smoother stops and to put less strain on your vehicle. |
Light-duty towingIf you’re towing a simple boat trailer or popup camper, a time-based trailer brake controller may be sufficient. CURT time-based controllers are easily adjustable for varying loads. |
Frequent towingIf you’re planning to tow often, an inertia-based brake controller is recommended. The sophisticated operation will help prolong the life of your vehicle and trailer. |
Occasional towingIf you only plan to tow a few times a year, such as for family camping trips during the summer, a time-based brake controller is an effective and budget-conscious option. |
Product Description
It takes a lot of power to stop a moving trailer, especially when that trailer is hauling livestock, construction materials, industrial equipment or other heavy-duty cargo. Play it safe when you tow and give your trailer brakes the control they need with a CURT trailer brake controller and brake controller harness. This brake controller wiring kit is designed for vehicles that do not have an included towing prep package. It includes cables, ring terminals, cable ties and a circuit breaker to splice into your vehicle's wiring system and allow installation of a CURT trailer brake controller. This wiring kit is compatible with systems with up to eight brakes.

However, some customers report issues with the cables and completeness. They say that the duplex wire is only 10 ft. long and that the black and white wire is way too short.

One suggestion: seller could throw in a brake signal wire tap in the package so it could save buyers a trip to auto parts store.
