Video Transcript for Hands-On with the Curt Tow Bar Extension Cord w/ Socket

Hello everybody, this is Jeff etrailer.com. Today, we're gonna take a look at this Curt eight foot long tow bar seven way RV to four wing round coiled extension cord, with the plug-in socket. Now this part is ideal for connecting your motor home to your tow vehicle for flat towing that vehicle. It includes this four way round socket here, that'll wire into the front of your tow vehicle. So, when you plug it in, it'll provide the operation of the tail lights, the brake lights, and the turn signals on your towed vehicle. The adapter cord connects the seven way blade style connector on your RV.

Just plugged that in. And then it goes to this four way round connector, that'll plug into this socket, that's wired on your vehicle. All you have to do is just line it up, slide it in. Once you slide it in, that cap, the top lid will hold it into place, and now you're ready to go. It provides the lighting you need.

It is a nice coiled cord, as you can see here. So will stretch up to about eight feet long. So, when it does, being coiled, it's nice because it prevents the wires from dragging on the ground. It is a durable molded plastic construction, does resist corrosion. And you can see the cord has a nice blue color to it for easy visibility.

But that should do it for the review on this Curt eight foot long tow bar, seven way RV to four way round coiled extension cord with the plug-in socket..

Nice looking. Problem I have is the 4-way is larger (only slightly, but enough to not fit).

    What you have is the Curt # C49HR which is a 7-way RV to 4-way round. If you don't have a 7-way on your motorhome you will need to add one with the # ETBC7 along with extra wire # 10-2-1. Then you could use the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152. You will also need a battery disconnect # RM-766 if you don't already have one.
