If you want a direct, factory-style replacement for your specific GM truck dashboard without worrying about wiring harnesses or complex setup, choose A-Premium Trailer Brake Control; if you need a universal time-delay controller with a digital display and adjustable braking force for varied trailer loads like ice fishing gear, choose Lrichy 8507111.
• A-Premium Trailer Brake Control: Its biggest strength is the precise vehicle fitment for 2014–2021 GM trucks with a direct snap-fit dashboard mount that mimics the original equipment design; its trade-off is the lack of advanced features like manual adjustment levers or digital displays, making it purely a functional switch replacement.
• Lrichy 8507111: Its biggest strength is the upgraded time-delay technology with an LED digital display and manual override lever that allows fine-tuning of braking power for different loads; its trade-off is the requirement to purchase a separate vehicle-specific harness and the more complex installation process compared to a plug-and-play OEM unit.
• The A-Premium unit is strictly for owners of compatible Chevrolet and GMC models who want a seamless, no-fuss restoration of their existing brake control functionality.
• The Lrichy unit is ideal for DIY enthusiasts, those with mixed vehicle fleets, or anyone towing heavy trailers who needs the ability to manually adjust braking force on the fly.
The A-Premium Trailer Brake Control Switch is designed with one clear purpose in mind: to restore the exact functionality of a missing or broken factory brake controller in specific General Motors vehicles. When I look at the specifications, particularly the terminal quantity of eight and the pin-type connector gender, it becomes obvious that this part is engineered to slot directly into the pre-existing wiring loom of your dashboard. It is not a standalone device with its own screen or buttons; it is the internal switch mechanism that your truck expects to find. This makes it the perfect solution for someone who has lost their original control unit due to wear, damage, or a previous owner removing it, but who wants the system to work exactly as the manufacturer intended without any aftermarket modifications.
The fitment data confirms this targeted approach. It is compatible with a wide range of popular GM platforms, including the Silverado 1500, 2500 HD, and 3500 HD series from 2014 through 2019, as well as the Colorado, Tahoe, Suburban, Sierra, Yukon, and Canyon models spanning 2016 to 2021. If your vehicle falls within these years and models, the attachment method listed as "Direct, Snap Fit" suggests a straightforward swap where you simply unclip the old unit and click the new one into place. There is no need to run new wires or drill holes. The reference numbers TBM003, 84108373, and 23145874 further cement its identity as a direct replacement for the OEM part number 23145874.
Who should buy this? You are the right candidate if you drive a 2014–2021 Chevy or GMC truck and your current brake control switch is dead or missing. You want a solution that fits perfectly without requiring a degree in automotive engineering. You are happy with the standard braking behavior provided by the factory system and do not need extra features like a digital readout or a manual slide bar. However, you should skip this product if your truck is not on the compatibility list, if you need to upgrade to a newer controller with modern safety features, or if you prefer a universal controller that can be moved between different vehicles. This part is a repair tool, not an upgrade tool.

The Lrichy 8507111 takes a completely different philosophy, offering a comprehensive time-delayed digital brake controller rather than just a simple switch. The core of this unit is its ability to gradually increase braking force at a fixed rate, which prevents the jerky stops often associated with older proportional controllers. This feature is particularly valuable when towing heavy loads that might shift during transit. The inclusion of an easy-to-read LED digital display adds a layer of transparency, showing settings, real-time diagnostic information, and alarms so you always know what the system is doing. Unlike the A-Premium unit, this is a standalone device with its own interface, featuring a manual lever on the left that allows you to apply trailer brakes independently of the foot pedal, giving you full control over stopping power.
Compatibility here is broad rather than specific. The Lrichy 8507111 is designed to replace the Brakeman IV and works with a vast array of manufacturers including Ford, GM, Chevy, Dodge, RAM, Toyota, and Jeep. It supports trailers with 2, 4, 6, or 8 brakes, covering everything from 1 to 4 axles. However, this versatility comes with a caveat noted clearly in the specs: the vehicle-specific plug-and-play harness is sold separately. This means you must ensure you have the correct wiring adapter for your specific truck model before installation. The mounting hardware included includes brackets and screws, and the unit is flexible enough to be installed in any direction, horizontal or vertical, without affecting performance.
This product is for the DIY installer who wants more control over their towing experience. It is also the choice for someone who owns multiple vehicles and wants a single controller they can move around, provided they source the correct harnesses. The two-year warranty service and free exchange policy add a layer of security for those concerned about long-term reliability. However, you should avoid this unit if you are looking for the absolute simplest possible install with zero additional parts to buy. If you are uncomfortable sourcing wiring harnesses or if you prefer a hidden, factory-integrated look over a visible digital display mounted on your dash, the Lrichy might feel too intrusive or complicated. It is built for users who want to tune their braking, not just turn it on.
• Best for Direct Replacement: A-Premium Trailer Brake Control wins instantly if you have a compatible GM truck and need to swap out a broken OEM switch without buying extra parts.
• Best for Adjustable Braking: Lrichy 8507111 is superior for drivers who need to manually adjust braking force via the lever or monitor real-time diagnostics via the LED display.
• Installation Simplicity: A-Premium requires only a snap-fit connection to existing wiring, whereas Lrichy requires purchasing a separate harness and mounting brackets for a custom install.
• Vehicle Compatibility Scope: Lrichy covers almost every major brand (Ford, Toyota, Dodge, etc.), while A-Premium is restricted strictly to specific years of Chevrolet and GMC models.
• Feature Set: Lrichy offers time-delay technology and digital feedback; A-Premium offers a raw, mechanical switch function with no digital interface.
• Warranty Coverage: Lrichy provides a two-year warranty, while A-Premium offers a one-year unlimited-mileage guarantee, though both cover quality issues.
• Mounting Flexibility: Lrichy can be mounted in any orientation due to its universal design, whereas A-Premium is locked to the specific dashboard location of the GM vehicle.
• Best for Ice Fishing: For the specific demands of ice fishing, where you might tow a heavy camper or sled across uneven terrain, the Lrichy 8507111 is the better choice because the time-delay feature prevents sudden jolts that could destabilize a load on slippery roads.
In my opinion, the Lrichy 8507111 is the smarter investment for most independent buyers, especially those planning trips like ice fishing where road conditions are unpredictable and load stability is critical. The ability to manually modulate braking force and see the status on a digital display gives you a level of safety and confidence that a simple replacement switch cannot match. While the A-Premium unit is excellent for a quick fix on a GM truck, it lacks the adaptability needed for diverse towing scenarios. I would buy the Lrichy because it transforms a basic towing capability into a controlled, safe operation, provided you are willing to handle the slightly more involved installation with the separate harness.
No, the A-Premium Trailer Brake Control is strictly designed for 2014–2021 Chevrolet and GMC models like the Silverado, Tahoe, and Sierra; it will not fit other brands.
Yes, the Lrichy 8507111 does not include a vehicle-specific plug-and-play harness; you must purchase the correct adapter separately for your truck's make and model.
The Lrichy 8507111 is better suited for heavy loads and rough terrain due to its time-delay technology and manual override lever, which allow for smoother, more controlled braking.
While the Lrichy includes mounting brackets and screws for DIY installation, connecting the wiring harness may require some automotive knowledge or a professional technician depending on your comfort level.
