Proportional Brake Controllers
If you are pulling a heavy RV or equipment trailer, you need an electronic brake controller. Hopkins proportional controllers (like the InSIGHT or Agility) use internal accelerometers to sense how hard you are pressing the brake pedal in your truck, and apply the exact same amount of braking power to the trailer axles for smooth, jerk-free stopping.
Simple Plug-In Vehicle Wiring
Avoid the nightmare of cutting, splicing, and soldering wires. Hopkins offers custom vehicle-to-trailer wiring kits. These harness connectors plug directly into your vehicle's OEM taillight assembly and provide an instant 4-way flat connector to power your trailer's stop, turn, and tail lights securely.
Frequently Asked Questions
What is the difference between a 4-way flat and a 7-way round trailer connector?
A 4-way flat connector only provides basic lighting functions: right turn, left turn, brake lights, and running lights. A 7-way round connector provides those same lighting functions, but adds circuits for electric trailer brakes, a 12V auxiliary power feed (to charge RV batteries), and reverse lights.
What is a Hopkins Time-Delayed brake controller?
Unlike proportional controllers, a time-delayed brake controller applies a pre-set amount of braking power to the trailer after a set amount of time once you touch the brake pedal. While they are more budget-friendly and can be mounted at any angle, they do not provide the exact 1-to-1 smooth braking feel of a proportional unit.
