Wiring a trailer doesn’t have to mean tracing wires or splicing into factory circuits. The Curt T-Connector plugs directly into existing tail light connectors to give you a 4-flat trailer plug. It’s a simple plug-and-play setup that gets you ready for towing lights without any guesswork.
This harness includes an inline converter that makes sure the trailer’s stop, turn, and running lights all work correctly. It takes care of combining or separating signals as needed so the trailer lights match what the vehicle is doing every time you brake or turn.
Unlike powered kits, this setup doesn’t need a run to the vehicle battery. It pulls the power it needs from the tail light wiring, which makes installation quicker and cleaner. That means fewer wires to route and no extra fuse connections to worry about.
The 4-way flat connector gives you the standard lighting functions—running lights, turn signals, and brake lights—so it works with most small or mid-size trailers. You can also add a 4-to-7 adapter later if you want to hook up a 7-way plug for more advanced towing setups.
This will not affect how the tail lights on your vehicle operate.
