Features to know about

Handles Any Trailer Setup: 7-Way and 4-Way Connector in One

Switching between different trailers is simple with this Multi-Tow connector. It combines both a 7-way blade and a 4-way flat connection on the vehicle end, so you can hook up small utility trailers one day and larger campers or boat trailers the next without swapping parts or using adapters.

Built for Everyday Towing: ProClass Construction

Made to hold up to regular towing, the TowSmart ProClass design uses solid materials that stay secure in the socket and keep a good connection even after repeated use. It’s built for reliability so your trailer lights and brakes work every time you plug in.

Clean, Universal Fit: Vehicle-End Plug for Easy Wiring Upgrades

This plug installs at the vehicle end as part of a trailer hitch wiring setup. The universal fit makes it a go-to choice for adding a dependable connector or replacing a worn factory plug. Once mounted, it gives you a clean, factory-style finish ready for towing duty.

Ready for Future Upgrades: Works with Common Harness Types

Because it’s designed as a vehicle-end connector, it pairs easily with most standard trailer wiring harnesses. Whether you’re wiring from scratch or updating existing tow wiring, the Multi-Tow plug keeps your setup flexible for whatever you plan to tow next.

Video Transcript for Review of TowSmart Custom Fit Vehicle Wiring - ProClass Multi Tow 7 And 4 Way Connector - TS87RR

Hi everybody. Andy here with etrailer. Let's take a quick look at this TowSmart ProClass Multi-Tow seven way and four way flat trailer connector. Now this is going to give you both a seven way and a four way trailer connector in one convenient housing as you can see here. So you're gonna be ready to tow a wide variety of trailers without needing adapters or separate wiring solutions. So whether you're pulling a small utility trailer with a four way plug or a larger trailer that requires a seven way connection, you're gonna have the right connector available.

The seven way connection gives you all the functions needed for those larger trailers, including running lights, turn signals, brake lights, electric trailer brakes, and a 12 volt charge line. That means that it's gonna be fully equipped for campers, enclosed trailers, car haulers, and other trailers that require more than basic lighting functions ins. Installation is going to be pretty straightforward because the vehicle side plug is gonna combine both the connectors into a single assembly. Once installed, this is going to mount neatly near your hitch, giving you a clean, professional looking setup. It's gonna be make it very easy to plug in your trailer whenever you're ready to tow.

The connector is built for long term durability. It's weather resistant ProClass designs are gonna help protect the terminals from moisture and corrosion. That's going to ensure a dependable connection even when exposed to road spray and other harsh conditions. If you notice here the seven way cover here, it is spring loaded, so it's gonna, when you let it go, it's going to close firmly by itself. And on the four way flap, you're just gonna push that down manually like that.

But especially on that seven way here, we have a gasket here that once that's closed, it's gonna do a great job of protecting the inside there. And then for the four away, we've got like an enclosure here, so that actually closes over that plug. So it's gonna keep that protected as well. You might want some measurements, so let me give a ruler here real quick. Give you a few, looks like we're three and a half inches wide by right at about three and let's call it three and a quarter inches tall or so.

Overall depth, about three and three-quarters inches. I think that's gonna wrap up our quick look today. Again, my name's Andy. Thank you for joining me.
