When you just need a clean, basic wiring setup for your trailer lights, this harness gets it done. The Curt 4-pole flat connector gives you the standard running, turn, and brake light functions in one neat plug. It’s a reliable way to power the essentials without adding anything you don’t need.
The 48-inch lead gives you enough slack to route the harness exactly where you want it. Whether you’re connecting near the hitch or need a little extra length for a tidy install, that extra reach makes wiring simpler and cleaner.
If your setup calls for a direct splice into existing wiring, this harness is made for it. The plug and lead design gives you straightforward wire ends that are easy to match up and secure. It’s a practical choice when you want to build or repair your own trailer wiring the right way.
This harness keeps things simple—no converter box or tow-package electronics to deal with. It’s ready to connect directly to standard trailer lighting circuits, making it ideal for basic towing setups that just need dependable light signals every time you hook up.

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a brief look at this CURT wiring harness with four-pole flat trailer connector. This universal, splice-in wiring harness is going to let you wire your trailer so that you can connect the trailer's wiring to your vehicle's during towing. Now, the length of this harness is 48 inches long. And as you can see, I have it bundled up here for manageability on my tabletop.
And this is designed for use with two-wire electrical systems. And of course, the four-pole flat trailer end connector is going to plug into the four-way flat on your tow vehicle. And the color coded wires are going to allow for simple hardwiring to existing trailer connections. And in case you don't know, the white wire here is going to be your ground wire. The yellow wire is going to be your left turn and brake light.
The green wire is going to be your right turn and brake light. And then finally, the brown wire is going to be for taillights. Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me.
