Trailer Brake Control Harness Reese 7805111 1-3 AXLES

Reese Towpower Towing Brake Control Harness (Part # 7805111) and what it is and how it’s used:

📦 What This Is

This is a brake controller wiring harness specifically made to connect a trailer brake controller to your vehicle’s factory tow package or under-dash connector. It’s not the brake controller itself — it’s the electrical wiring that makes installation much quicker and cleaner than splicing your own wires. 

🔌 What It Does

• Provides a pre-wired OEM-style connection between your vehicle and a trailer brake controller.

• One end plugs into the factory brake control connector on your vehicle (if so equipped).

• The other end plugs into the brake controller unit under your dashboard.

• Designed to reduce installation errors, shorten install time, and eliminate messy splicing. 

🚘 Typical Use Cases

This type of harness is used when you want to install a brake controller like the Reese Towpower or other brand (e.g., Tekonsha) in a vehicle that has a factory-ready brake control connector or wiring harness. It’s a simple plug-and-play solution compared with cutting and crimping wires yourself. 

⚠️ Important Notes

• This harness alone won’t stop your trailer. You still need a brake controller unit (e.g., Reese Brakeman IV or a Tekonsha controller) for it to work.

• It’s often specific to certain truck/SUV models that came with a factory towing package — always check your vehicle’s fitment or install guide.
