Hi there Trailblazer runners, today on your 2021 Chevrolet Trailblazer, we're going to be taking a look at and showing you how to install Roadmasters crossbar style base plate. And this is what our base plate looks like when it's installed. You can see that the attachments are going to pass through the bottom here of our fascia. And this is a nice base plate cause it's given us places to mount our breakaway switch and our diode wiring. So you've just got everything you need right up here at front for you. It's a nice clean look.
The black powder coat finish blends in with the exterior of the vehicle really well. And it really just all looks like it was kind of meant to be there. There's five main components you'll need when flat towing your vehicle behind your motor home. You'll need your tow bar, which is the connection between your motor home and your vehicle. You'll need your base plate, which is the connection point on your vehicle that your tow bar will attach to.
You'll need your safety cables, which is a supplemental connection, in addition to your tow bar. You'll also need your diode wiring, which will take the lighting signals from your motor home, and transfer them to the lights at the back of your vehicle, so people will know your intentions when going down the road. And lastly, you'll need your supplemental braking system, which will apply the brakes in your vehicle when you hit them in your motor home to help you come to a safe stop. Some additional components you'll want to consider is a high-low adapter. This is what we've got installed here, and this is only necessary if the height of your motor home and your base plate differ more than three inches.
We've you've got an eight inch drop installed here, in order to give us a difference of only one and a half inches between the two, giving us a nice level tow bar here. Because if the angle is too extreme, what will happen is every time that you take off, you will either pull up, or down on the suspension on your vehicle. And that can prematurely wear out those components. By having it be completely flat like this, we're just pulling it straight, and we're not going to be affecting our suspension in any way. You will need to, to make sure that you got the additional pins so you can get these all attached.
Another thing that you'll maybe want to consider is your safety cables. If they are coily cables, in most cases, your, usually will have the length that you'll need, but, adding a high-low adapter does often make your straight cables not quite long enough. And we've got extensions here at each trailer, if you we're to need those as well, to ensure your cables are long enough. We're going to hook up to our motor home now. So I've pulled up to it. And when you're ready to attach to your motor home, we're going to take our crossbar style arms here. This is going to insert in place. We can click that one in. We'll take our other one. And you can notice that that they are labeled on them, so it makes it nice and easy to know which one goes on which side. The tabs here are also going to be towards the top. Once those have been clicked in, we can grab the crossbar. This just slides down on top, and then we'll simply secure it into place with the included pins. At this point, this base plate is now ready to attach to any Roadmaster tow bar, but we've also got adapters available here at each trailer. So you can take another manufacturer's tow bar and swap those out and get those two attached directly to this base plate as well. We can now go ahead and get a tow bar attached to it. So we're just going to take our tow bar here, get it out of our storage position. We'll spread our arms to line up with our base plate. We'll then slide that arm in, so the hole and the tow bar lines up with the hole in our base plate here. We'll grab our pin. We're going to slide it from the outside in. And on the opposite side, we'll secure it with the clip here. We can then repeat that procedure over here on the other side. And now at this point, we are ready to take our, the rest of our flat tow components, such as our diode wiring. Our safety cables, and when attaching your safety cables, we do want to make sure that we are crossing those. So we're going to take the safety cable from the passenger side there on the motor home, and make sure that we connect it to the attachment on the driver's side on our vehicle. We'll do the opposite with the other one. And this will ensure in the event of a catastrophic disconnect, that we will have a, cradle here, underneath of our tow bar to keep those components up from dropping d
