Questions & Answers

What exactly do the three leds mean?

That connection is currently being established.

Is it possible to cut the rubber cord that holds the led dust cover in place, or will this cause the lights to stop working? I don't want it to be dangling while I'm towing or launching the boat. ?

Why would you want to chop it up? This is a dust cover that also indicates whether or not all of the power for your lights is present. Is a useful troubleshooting tool that will not cause any harm.

Is it true that the blade and pin terminals are made of brass?

It has a brass-like appearance but isn't magnetic. So I'm going to say it's brass.

What is the method of operation of the tester? When I start my car, only one of the leds on my test cover lights up. Is this something that happens frequently?

Turning on your turn signals and braking will cause the lights to turn on. The fourth pin, which is always on, is for the running lights.

For Honda Ridgeline and Honda Pilot, this isn't a viable option

3/5

This was purchased for my 2017 Honda Ridgeline, but it does not fit tightly into the OEM 7 pin socket. The pins align and make contact, but the adapter is slid into the socket loosely. And the retention mechanism isn't going to work. With just a little pressure, the adapter will pop out. Owners of both the Honda Ridgeline and the Honda Pilot are reporting the same issue, according to the internet. If you own one of these vehicles, I would recommend that you look for something else.

The light feature is particularly appealing

5/5

It's nice to know how the plug works before you hook up the trailer because you won't have to guess what's wrong.

The 2015 Audi Q5 is being worked on

5/5

This is what I use to connect incandescent (not LED) trailer lights. This is an excellent choice. It works fine, and I like that we have test lights to ensure the adapter is in good working order.

It was a perfect fit for my 2021 Ford F150

5/5

Great product with easy-to-pull-out grips that make detaching a breeze.

This does exactly what it says on the tin

5/5

This is something I make use of. This does exactly what it says on the tin. This is what I used to make my 2016 Nissan Frontier 7 blade compatible with my small trailer.

Convert a 7-pin connector to a 4-pin connector

5/5

If you need a 7 pin to 4 pin adapter for your trailer, this is the one to get. Nobody sold an adapter for my VW Atlas, which came with the 7 pin (round) connector. This was a lot less expensive than the part that VW had forgotten to give me.
