Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Roadmaster coil tow bar power cord. Now, this cord is going to power your flat tow brake system, tail lights, diodes, and other accessories, and it is coiled so it won't drag on the ground. And this seven-way connector is going to plug into your RV and then the six-way round connector plugs into your towed car. And this does extend up to eight feet.
And this is durable. It has a UV resistant vinyl coating, so it's gonna hold up really well to the elements that it's constantly going to be exposed to, and it's gonna be a very easy installation. And if you decide that this is going to be exactly what you need, we would love to hear back from you regarding your experience with this cable. You can leave us a review on this product page or a comment, and if you leave a review, you can send us some photos of your towing setup and photos of this in action. We would love to hear back from you.
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.

That is correct Matt, I am very sorry you ordered this one. In order to install through sleeves on tow bars you would indeed need the # RM-1676-7 as it has the longer straight part to go through, then you will wire on the 6 way connector.
