When you just need a clean way to hook up trailer lights, this harness gets it done. The Curt Vehicle Wiring Harness with 5-Pole Flat Trailer Connector comes with a 60-inch wire lead that gives you enough length to route and position the plug where you want it. It’s the straightforward plug and lead setup that keeps things tidy and reliable.
Some wiring kits require converters or adapters, but this one doesn’t. It’s a splice-in design made for direct connections, so you can tie your circuits in cleanly without adding unnecessary parts. The harness is simple, functional, and ready to integrate into your existing wiring.
Each circuit in this harness uses 18-gauge wire for consistent strength and signal flow. That’s ideal when you’re wiring a setup that keeps the brake and turn signal circuits separate. You get a dependable connection that holds up over time and keeps your trailer lights working as they should.
The 5-flat connector supports the usual lighting functions—running, left turn, right turn, and ground—plus an extra circuit for reverse lights or another auxiliary function. It’s a versatile choice if you’re wiring up a trailer that needs one more signal than a standard 4-flat can handle.

Item just what I was looking for ..
Haven't used it yet. But it's wire to my car.
The harness appears to be well made. I won't get a chance to use it until Spring.
I received my order sooner than expected. Looks to be what I expected. Have not installed yet. Thanks!
Good product,good price,good shipping.Thank you etrailer
Nice inexpensive wiring kit if you arent afraid to diy. I had our van wired up in about 30 minutes.
Ordering was easy and delivery was prompt. I have not yet installed the product, but I found it to be just what I needed and the instructions are clear and concise. I would recommend this product and the website; easy to do business and the price is most competitive.
I wouldn’t buy nothing from etrailer. Tried to return the item I bought and was told to sell it online it would cost your company to much money to pay for shipping then the wiring cost in the first place.
Curt Custom Fit Vehicle Wiring for Toyota Highlander --
Piece of cake!! Installation basically a no-brainer, especially with the help of the video installation clip from e-trailer. Complete installation took less than 30 minutes including the modifications I made to the wire harness and the floor of the vehicle to get a permanent installation underneath the vehicle adjacent to the trailer hitch frame mount. I'll definitely get another wiring kit from e-trailer whenever this vehicle gets replaced.
Dummy me. I ordered this thinking that it was for my trailer, not my motorcycle. Customer service was outstanding in helping me obtain the correct one. I will definitely be ordering from them again when I need additional parts.
