It works with most light- and medium-duty trucks and SUVs and supports trailers with electric brakes on 2, 4, 6 or 8 brakes. Vehicle-specific plug-in harnesses are not included, so installation may require a harness or hardwiring depending on your make and model.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 90885 create smoother, more controlled stops?\u003c\/h3\u003e\n\u003cp\u003eThe 90885 reads your tow vehicle’s deceleration with an internal inertia sensor and modulates current to the trailer brakes in direct proportion. That prevents sudden, jerky engagement and helps the trailer track behind the tow vehicle naturally during routine and emergency braking.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal inertia sensor for real-time proportional output\u003c\/li\u003e\n  \u003cli\u003eDigital LED displays brake power and system voltage\u003c\/li\u003e\n  \u003cli\u003eManual override slider for immediate trailer braking control\u003c\/li\u003e\n  \u003cli\u003eMulti-level boost for heavier trailer loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat vehicles and trailer setups are compatible with this brake controller?\u003c\/h3\u003e\n\u003cp\u003eThis controller is universal in design and works with many Ford, GM, Chevy, Dodge, RAM, Toyota and Jeep models when hardwired or used with the appropriate vehicle harness.

The cermep auto 90885 suits owners of trucks and SUVs who tow trailers with electric brakes and want proportional, vehicle-synced braking without complex programming. It’s a good fit for occasional and regular tower alike who need smooth deceleration, clear diagnostics and added stopping power for heavier payloads. If you’re installing on a vehicle that requires a plug-and-play harness, plan to purchase the correct harness separately or consult an installer for hardwiring.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the controller need a vehicle-specific harness?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Not always.
