Questions & Answers

Why am I still getting the message "trailer brake not connected"? Is it possible to get a limited edition Ram 1500 in 2016?

To ensure that voltage reaches the trailer, check for voltage at the brake wire from the truck/plug. It's possible that the truck's fuse has blown. If that's the case, there could be a problem with the brakes or the harness.

My Toyota 4 Runner will not work with this adaptor. Is there a single one?

Yes, a 7-way round rv connector should be installed on your vehicle.

Is the "connector end to end" distance 16"? Is the 'cable' part 16" or is it the 'cable' part? I'd like to know how long it's going to take from start to finish. ?

The cable between the adaptors measures 17 inches in length, with a total length of 24 inches.

Is this compatible with the Ford F-150 2017 model? 150?

The 7- The round molded plug is made to fit into a standard 7-pin connector. Late-model vehicles, such as the Ford F-150, have round vehicle connections. 150

Recommendation for good quality

5/5

Very good quality, and a must-have for newer vehicles with a trailer wiring plug that is located a long way from the hitch. This adapter is compatible with all 5 pin and most 4 pin applications. I have a 2008 Ram with a 7-pin outlet all the way up near the license plate, which makes the non-standard outlet non-standard. Extended adapters aren't compatible with most trailers because the wiring rarely extends beyond 6 inches. The trailer hitch extends 8" beyond it.

Great quality for the price, and I especially like the fact that each connector end is hermetically sealed with thick rubber (some aren't)

5/5

I believe this will last for a long time.

5/5

I haven't tried it with my trailer yet, but I am confident that it will work. The price is reasonable.

Everything is as it should be

5/5

Perfect for switching from a flat 5 pin connector to a 7 pin connector on my trailer.

What I was looking for

4/5

It's quite effective. However, this is to tap into a 7-way / backup system, similar to the surge brakes on my boat trailer.

This trailer light adapter is very nice

4/5

This trailer light adapter does exactly what it says it will, and all of my trailer lights turned on right away. The car connection is a little tight, but with continued use, it should loosen up.

The cable is of excellent quality

5/5

Everything went smoothly. Many people will need these converters/extensions for their boats and trailers now that the connection is up around the license plate instead of under the bumper on newer trucks. The cable is of excellent quality.
