How to Install the Roadmaster Automatic Battery Disconnect on a 2019 Chevrolet Colorado


Today we'll be taking a look at the Roadmaster Automatic Battery Disconnect Switch as part of a complete plateau set up for your 2019 Chevrolet Colorado. We'll start with our baseplate which we'll be using Roadmaster's EZ5 Baseplate Kit. In addition, we'll be using Roadmaster's Duo Wiring Kit, SMI's Stay-In-Play Duo Supplemental Braking System, Roadmaster's Battery Charge Line Kit, Roadmaster's Automatic Battery Disconnect Switch, Roadmaster's Falcon All-terrain Non-binding Tow Bars, and lastly Roadmaster's 64" Single Hook Safety Cables. So, you're looking to flat-tow your Chevy Colorado. We've got our whole set up here and there's several components we're going to need to complete that. Let's go over those now.The first component you're going to need is your baseplate.

This is the interface that's going to allow your vehicle to be connected to your motorhome and pulled behind it. This baseplate is easy to install. You do have to remove the fascia, but there is no drilling required. It replaces your factory tow hooks, and is squeezed between the bumper beam. It's going to provide you an attachment point for your safety chains, as well as a place to hookup any Roadmaster tow wire.

You can hookup other brands using adapters found here on our website. When not in use, the connection point for your tow bar is removable. Simply pull the pin, twist it and pull it out. This'll give you a more factory appearance.The next component is our diode wiring. This wiring kit allows you to transfer signals from your motorhome through the included cable, down to our connector, and to the lights at the back of our vehicle.

Our diode wiring is going to connect into both our passenger and drive-side taillight assemblies, intercepting the turn and taillight signals. As you can see here, we have our right turn signal, left turn signals, tail lamps, and brake lamps.The next component is our SMI, Stay-In-Play Duo. That's an electric supplemental braking system. It uses signals from the motorhome, as well as an inner sensor to proportionally apply the brake pedal to assist with stopping. The operating unit located under that hood, taps into the brake vacuum system, and uses air pressure to apply the brake pedal.

Our braking system also includes a breakaway switch. This safety device has a cable attached to it, so in the event of a catastrophic disconnect, the pin will get pulled, applying our braking system to help our vehicle come to a safe stop.When the braking system pulls the pedal, it'll eliminate the LED on the backside of our mirror. This way we know the system's working properly. While this system is designed for a motorhome that has hydraulic brakes, if you have air brakes on your motorhome, you can get SMI's Air Force One. It installs fairly similarly, but is designed to work with air brakes on your motorhome.For our Colorado, we'll also need a battery disconnect. This allows us to disconnect our battery from the vehicle with a touch of a button. Since our vehicle requires the battery to be disconnected when placed into tow mode, this way we can do it quickly and easily. Our wiring just connects to the battery, and then to a switch that you'll mount inside your Colorado. Now, when we press our button, it'll disconnect our battery. When we press it again, it'll reconnect our battery.We've also installed the battery charge line kit. This will allow our motorhome to charge our batter as we're going down the road. And now even though our battery is disconnected, it is powering our braking system and a few other components. This way we can ensure when we get to our destination our battery's going to be charged up and ready for us to start our adventure. We'll attach it to the center post on our six pole connector, and that way it'll receive our charge from our motorhome to this circuit.You've now all the necessary components installed on your Colorado, but you need a way to connect that to the back of your motorhome. We're going to be using Falcon's All-Terrain Tow Bars to do this. As the Falcon All-Terrain is a Roadmaster product, it easily connects to our base fit that we have installed.The quick connect arms on our baseplate will easily attach to our Falcon's arms. We slide those down in the slot there. We take the large pin, slide it through both arms, line up the hole on the opposite side, and put the locking pin down and in it, making sure to fold it over so it can't become disconnected.Our tow bars are non-binding. This is great because if you're parked on uneven terrain, it can be difficult to disconnect it from your baseplate. You simply pull the lever and that'll allow the arms to free up, slide in and out, making it easy to get them disconnected.I think the last is just to wrap your safety cables. What I was thinking about the All-Terrain, is that it has a channel on each arm to route your wiring and cable through. We simply slid those through, made our connections at our baseplate, and then our motorhome side, making sure to cross your safety chain cables, hook up your wiring, which we also ran through the other arm. We have our southern pole on our motorhome side, and our six pole on our vehicle side, and then hook up our breakaway switch for our braking system.Depending on your RV, you may need a hi-low adapter. You want to be towing as level as possible. Since our RV is so much higher than our vehicle where the baseplate is, we are going to be using a 6" drop here to level that out. Now, we can take a look at our Colorado as it's flat towed behind our motorhome.That completes our look at a complete flat tow set up for our Chevrolet Colorado.
