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.

Very easy install!
Install was straightforward and fit was perfect.
Curt products are uniformly excellent. Great design, materials, construction, instructions, and function. Easy to install and work perfectly.
Product is delivered fast and will be a breeze to install once the weather cooperates to do so. Glad to use e-trailer for there good selection on all my towing needs, Thanks again e-trailer!!
Wire harness plugged easily into my 95 Nissan Pathfinder. Works perfectly!
This splitter works great. It was easy to install and tuck out of the way. The 4 way plug is high quality also.
The T-Harness again is very well made. A way better option than the subpar splice job I bought the vehicle with, but again with the instructions. If you’re installing the harness on a hardbody (pickup) it’s your lucky day. If it’s a Pathfinder, go ahead and just throw those instructions away and figure it out for yourself. I wish that Curt Mfg would put as much effort into their instructions as they do their products. But you know what they say… wish in one hand.
Fast shipping and just what I was needing. Thanks
This is my second set of trailer connection wires for my Nissan hardbody’s. I just bought my second truck and had to buy the trailer connection wires this set makes it so easy to install and it works great.
Fits fine, but in my application I've replaced the stock bed with a flat bed, so had to replace the open back connectors with sealed versions. Having a sealed version available for an extra cost would be worth it to me.
Installed with no problem.
