Adding trailer wiring usually means cutting into factory wires, but this harness avoids that. The Curt T-Connector plugs directly into the tail light connectors, giving you a clean 4-flat trailer connection. It’s a straightforward plug-and-play setup that keeps your factory wiring intact.
When you hook up your trailer, the powered converter keeps the vehicle’s electrical system from being overloaded. It draws power straight from the battery instead of other circuits, so your trailer lights won’t dim or shut off due to shared power. That extra protection keeps both systems running smoothly and safely.
If your vehicle didn’t come with a tow package, this harness makes it easy to add one. The included power lead runs right up to the battery, giving you everything you need for proper trailer lighting. It’s a smart fix for anyone setting up towing for the first time or upgrading from a basic setup.
The 4-pole flat connector provides running lights, turn signals, and brake lights—everything needed for standard trailers. Once installed, it delivers reliable communication between your vehicle and trailer so your signals always stay in sync on the road.

I personally haven't ever seen someone add the hole to the bumper for the 7-way...it looks so clean! Thanks for sharing the photo and your genius!
