How to Install the Demco SBS Stay-IN-Play DUO Supplemental Braking System on a 2020 Jeep Wrangler


Clayton: Hey guys, how's it going Clayton here at etrailer.com. Today, we'll be taking a look at and I'll show you how to install Demco Stay-IN-Play DUO supplemental braking system on a 2020 Jeep Wrangler. So our supplemental braking system is going to keep us safe on the roadway. Worst case scenario, if our tow bar comes disconnected from our vehicle, our breakaway switch will be pulled and it'll apply the brakes in our Jeep, stopping our vehicle and keeping everybody else safe. Our supplemental braking system is one of the key components in a flat tow setup. So we do have supplemental braking system, our wiring, our safety cables, our base plate, our tow bar, and our stoplight switch.So one really nice feature about our kit, is it has an inertia switch.

That inertia switch, is going to sense whether we're breaking or just traveling down the road. That way, if we are breaking, it'll apply the brakes using the signal from the motor home. One really nice feature of our kit is we have an indicator light. We stuck that on the back of our mirror. And all that does is it lets us know whether our system is working or not working.

So if we're waiting to turn it'll flash, or if the brakes are being applied, it'll flash straight red. Our kit is going to come with an actuator. What this does is it pushes our brake pedal down, applying the brakes when we use our brakes in our motor home. So this is what it looks like when it's working. As you can see, it's pushing our brake pedal down.

Then when we take off the brakes, the peddle releases.Located right here is our G-Force controller. What this does is it allows us to put our vehicle in tow mode. So when we're ready to tow, we slip this over and then we follow the instruction manuals listed in our vehicles or owner's manual. And that'll tell us how to put the rest of the vehicle and tow mode. This is very nice because it's super easy.

Just to flip a switch. You do want to make sure when you install it, that the Demco logo is facing the passenger side. And this is our operating unit, the best place to mount it on our vehicle, was underneath our driver's seat. But there are a couple of different options that you could explore with mounting it in your engine bay or behind your front bumper.This is going to be the main signal for when we're sneezing our brakes. This is going to have our vacuum line and our airline tube that connect to our G-Force controller and our brake booster and the engine compartment. So in terms of installation, installing the supplemental braking kit really isn't that bad. It can be kind of tedious because you're dealing a lot with wiring, but if you take your time, it should be pretty straightforward. Now, since we've talked about installation, I'll walk you through how we installed ours.So this is what our operating unit is going to look like installed. But our first step is finding a good place to install it. We chose underneath the driver's seat. As you can see, I've taken out the driver's seat, gives us a little bit more room to work, but before you mount your box, you want to take the driver's seat, put your box underneath it and make sure you still have full motion of your seat. We ran our wires from the box underneath the carpet and through this kick panel made our connections back here. And then we ran our three wires that tie into our four pole harness out of our firewall.So our wires came out of the firewall here. I had to add a connection to our brown wire. I had green wire, so I used green, ran that over by our power. That also ties into our brake light switch. I then ran our blue wire for our breakaway switch up this way, kind of behind all these hard lines, dropped it down and made our connection at our breakaway switch. So our brake light switch is located directly up here. It's kind of hard to see, but one of those wires, runs out to power and our other one, connects to our indicator light. As you can see, our actuator is mounted here and put our bracket there on the back, make sure we have been pedal travel. And then I ran the rest of our wiring up through the firewall and tucked everything that I could behind our kick panel here. Our airline tube comes up this way, sweeps down, comes back through this kick panel to our operating unit.It's very important to make sure that there aren't any kinks and your line can still move. Our indicator light is mounted on the back of our mirror post. Our mirror is textured, so our adhesive didn't stick very well. And it stuck here good, and it's not going to block our line of sight. Our wire runs up this way, drops in through this panel runs all the way across, down by our handhold and then tucks down behind our paneling and straight down to our other wires. To get our four-pole wiring and our breakaway switch wiring, I had to drill a couple holes. I drilled a hole right here, ran our four-pole wiring into the back and connected it to our plug on the opposite side of our breakaway switch here, there's a small hole, and I ran the wire through that hole and made our connections to our blue wire underneath of our front panel.So from our breakaway switch, there's one wire that has to come to power. The wire right off of our switch is orange and black. I had to extend that using a yellow wire to get that wire long enough to connect it to our battery. Our other wire here is that brake light switch that has to be connected to power as well. So these wires right here come from our operating unit. Those ran up through our firewall, I dropped them straight down, came into this hole and pulled them through on this side. These are all of our connections from our four-pole to our operating unit wiring. This ground here is a double ground based off of this wire. I always like to put this ring terminal behind a bracket just for a little extra protection.And when we're done, we can tuck all this into our frame rail, but we don't have to worry about it getting damaged. And it's a really good idea to add wire room, just to protect this wire. So it doesn't rub a hole in it off of that hole on our frame. So now that we have everything hooked up, we can connect our power at our fuses and test everything out. So as you can see our breakaway switch is up now, when we pull it, you can hear the actuator actually at the brakes inside of our vehicle. So that's going to do it for a look at the Demco Stay-IN-Play duo supplemental braking system on our 2020 Jeep Wrangler..
