Switching between trailers with different connectors doesn’t have to mean carrying extra cords. This TowSmart adapter converts a 7-blade socket to either a 4-flat or 5-flat plug, so you can hook up a wide variety of trailers without rewiring. It’s a simple plug-only design that connects right to your existing 7-way outlet.
No wiring, no tools—just plug it in and you’re ready to tow. The adapter’s one-piece design means there’s nothing to splice or modify. It’s built for quick swaps between trailer types when you’re moving from utility trailers to boat trailers or anything in between.
From small cargo haulers to marine trailers, this universal adapter handles both 4-pole and 5-pole connectors. It’s a handy solution when you tow multiple trailers or share vehicles, keeping your setup clean and compatible without extra wiring kits.
The solid plug body resists wear from frequent connects and disconnects, and its compact size makes it easy to stash in the glove box or toolbox. It’s a simple, reliable piece that keeps your trailer lights working wherever you go.

Hi, everybody. Andy here with etrailer.com. Let's take a quick look at this TowSmart adapter, seven-pole to four-pole and five-pole. Now, this seven-way blade to the four or five-way flat trailer light wiring adapter is gonna be the quickest and easiest way to make electrical connections when hauling a trailer that has a different wiring configuration than your vehicle. This adapter is gonna be great for trailers that require a four or five-way flat connection, but have a seven-way blade towing vehicle. This adapter will obviously connect your tail lights, brake lights, turn signals, and reverse lights.
You notice we have these caps here that are going to cover up those connection points when it's not in use, so that's a nice addition. This single-housing design plugs into your vehicle's electrical socket and requires no wiring. It gives you a ergonomic, durable plastic construction, so this is going to be corrosion resistant, it's gonna hold up to the elements that it's gonna be constantly exposed to. It's gonna be very easy to use but very practical and give you some options there when you need them. Well, I think that's gonna wrap up our quick look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
