<h3>Hayes Towing Electronics: A Legacy of Safer Towing</h3><p>When it comes to controlling trailer brakes, few names carry more history or authority than <strong>Hayes Brake Controller Co</strong>, also known as Hayes Towing Electronics. The brand's roots stretch back to the 1950s, when The Kelsey Hayes Company in Detroit, Michigan invented the very first hydraulic-over-electric trailer brake controller — a system that required a direct connection to the tow vehicle's air or hydraulic braking system. By the 1970s, Hayes was once again at the forefront, pioneering the shift to the proportional electronic brake controller that remains the industry standard today.</p><p>Over more than six decades, Hayes has built a reputation for engineering products that dealers and drivers alike can trust. Their controllers are engineered around a core commitment to safety: in a manual braking application, Hayes controllers ramp to 100 percent braking power — not just a preset level — meaning full stopping force is available exactly when it's needed most. It's that kind of real-world engineering philosophy that has made Hayes a go-to choice for towing professionals and weekend haulers alike.</p><h3>The Quik-Connect&reg; Advantage</h3><p>One of the most praised features across the Hayes lineup is the proprietary <strong>Quik-Connect&reg;</strong> system. All of the brand's electronic controller models use an exclusive four-wire connector that pairs with vehicle-specific wiring harnesses, allowing the brake controller to be essentially plugged in without hard-wiring. This dramatically simplifies installation across a wide range of trucks and SUVs, eliminating guesswork and reducing the chance of wiring errors. The system also activates trailer stop lights when the brake control is manually triggered — a critical and often overlooked safety benefit.</p><p>Hayes controllers are compatible with 2, 4, 6, or 8 electric trailer brakes, making them versatile enough for single-axle utility trailers up to heavy four-axle loads. Their product ecosystem spans <a href="/14161-trailer-brake-control-hayes-brake-controller-co-7382">trailer brake controllers</a>, <a href="/200201-brake-actuators-hayes-brake-controller-co-7382">brake actuators</a>, supporting <a href="/200202-brakes-brake-parts-hayes-brake-controller-co-7382">brakes &amp; brake parts</a>, <a href="/7382-hayes-brake-controller-co-electronic-brake-control-wiring-harness-22684">electronic brake control wiring harnesses</a>, and <a href="/7382-hayes-brake-controller-co-electronic-brake-control-relay-3316">electronic brake control relays</a> — everything needed to build or upgrade a complete trailer braking system.</p><h3>Part of a Trusted Towing Family</h3><p>In October 2023, Hayes Towing Electronics was acquired by Hopkins Manufacturing Corporation, joining Hopkins Towing Solutions — one of the most recognized names in towing electrical products. This union further strengthens Hayes's position in the market and ensures continued development of reliable, installer-friendly brake control technology.</p><p>Whether you're towing a boat, an RV, a horse trailer, or a heavy equipment haul, Hayes products are engineered to deliver confident, proportional braking performance with straightforward installation.
