Jeff Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this CURT seven-way trailer adapter for towing trailers with LED lights. Now, this'll basically plug into your existing seven-way socket, and it provides a new seven-way socket that's able to recognize LED trailer lights. They use built-in resistors, which'll enable the LED signals from your trailer to be read by your vehicle's computer. And to install this, there's no cutting or splicing required. It's basically just a plug-in.
This is great for use on the vehicles with the trailer lamp out sensors, like the Audi, the Mercedes and the Volkswagen vehicles that have the factory tow package. What this adapter will do is simulate the increased power draw so the vehicle thinks there's incandescent lights on the trailer. Then you won't get the lamp bulb out reading that usually flashes on the dash of those vehicles. You can see it also, right here, has a nice spring-loaded dust cover. This'll help protect the terminals from moisture and debris when the connector is not in use.
Overall length on this from one end to the other is about 12 inches, and you can see it is a flexible cable. But that should do it for the review on this CURT seven-way trailer adapter for towing trailers with LED lights..

Glad we had the fix for you Mark! Not sure why the LED lights don't like to play with the Chevy/GMC wiring. They will get it figured out one day =)

What brake controller are you using, or is it the OEM one? What is the year and model of your Chevy? Are they just electric brakes, or electric over hydraulic? And can you please explain the issue? Just trying to dig a little deeper so we can get you sorted out =)

It still works. I wish there was a sleeker version.
Do you have a question about this Custom Fit Vehicle Wiring?

Hi k-dub, thank you for the update. This 7-way adapter is more for the trailer lamp out sensors, not trailer disconnected sensor. I did a little research on that issue with the Ford and it seems to be an issue with the pins of the 7-way on the trailer side. They don't always fully seat with the 7-way plug on the truck. Is the 7-way cord on the trailer side an older plug?
