Video Transcript for Review of TowSmart Custom Fit Vehicle Wiring - ProClass Plug In Trailer Adapter With Tester - TS89RR

Hi everybody, Andy here with etrailer.com. Let's take a real quick look at this TowSmart pro class plugin trailer connector adapter with wire tester. Now, this TowSmart pro class adapter is going to convert your four-way flat vehicle wiring to fit a seven-way trailer plug, and it is a plug and play solution for light duty towing. If you notice, we do have a built-in LED tester that's gonna confirm that brake lights, tail lights, and turn signals are working. And the molded grip is gonna make it very easy to plug this in and remove it without tools. As you can see, we do have this loop here, I think they call it the euro grip that you can use to pull that out.

So it feels like it's pretty durable construction on the four way flat here. You've got a a tethered cap there to keep that plug protected from moisture, dirt, debris when it's not in use. But I think that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
