You're lining up the trailer in the driveway when you realize the plug doesn't match. No time to rewire. You mount the bracket, snap in the adapter, and the lights fire up. Quick install, solid connection, and you're back on schedule.
This plug-and-play adapter converts a 7-way blade socket to a 4-way flat trailer plug, allowing you to tow trailers with different wiring configurations. The single housing design plugs into your vehicles electrical socket and requires no wiring. It provides a sealed plastic construction that helps block out moisture and grime.

Hi, everybody, Andy here with etrailer. Let's take a quick look at this TowSmart multi-tow seven-way blade and four-way flat trailer connector. So this is gonna be compatible with your Ford GMC and Dodge trucks with the factory tow package. So this is basically going to be a plug and play harness that's going to add both a seven-way and a four-way connector, as you can see there. Now, the seven-way connector has a flap or cover here that's spring loaded. So that's going to close like that, and then you'll just push down the four-way just like that.
If you notice, we do have a like a little gasket in here on that seven-way to keep moisture out, and we have an enclosure right here on that four-way to keep that connector protected when it's not in use. So this is going to allow for a multiple trailer type to give you the ability, rather, to run multiple trailers, and this is going to be a very clean install. You're not gonna have to worry about splicing. This is gonna mount neatly near the hitch. It's gonna give you a reliable connection for those trailer lights and brakes, and some measurements might prove helpful for you.
So looking at what I'm calling the width here, we're sitting right about three and a half inches wide. The height about, let me come around and take a look here, say, right at three inches, it looks like, pretty close, tall. The thickness, right at about one and, let's call it one and seven-eighths inches or so. Now, if you happen to have any other questions about this, don't hesitate to reach out. We do want to make sure that you're getting exactly what you need, but very durable.
It's constructed of high density plastic. So it's gonna resist the elements that it's going to be constantly exposed to, but, again, my name is Andy. Thank you for joining me.

I'd be happy to help. Can you explain further? What's the year/make/model vehicle you have?
