How to Install the Brake Buddy Stealth Supplemental Braking System on a 2020 Jeep Wrangler Unlimite


Hey everyone. Shane here with etrailer.com. Today I have a 2020 Jeep Wrangler unlimited. I'm going to walk through how to install the brake buddy stealth supplemental braking system for towed vehicles. It's going to be one of the main components needed to flat tow your Jeep. The other ones are going to be your tow bar, a base plate, if you don't have an off-road bumper, if you have an off-road bumper you're gonna need D-ring adapters to attach to the tow bar, safety cables which are a secondary safety device in case you have an accidental disconnect, and then of course your wiring.

Our wiring allows our motor home to transfer light signals to the back of our towed vehicle or to our Jeep when it's being flat towed. So that everybody knows what we're doing whether that's braking, turning, or driving at night. For this braking system, this cable comes with the braking system and all of our light signals are transferred through this as well as everything for a braking system. Our tow bar is a connection point between our towed vehicle and our motor home. As I mentioned, our D-ring adapters are designed for your off-road vehicles or our vehicles with off-road bumpers.

One thing to keep in mind if you have an off-road bumper with D-rings on it contact the manufacturer of the bumper to make sure that the bumper is compatible to be used to flat tow the vehicle. Cause not all of them that have D-rings on them can be used to flat tow. Our braking system is designed to allow the vehicle to not only slow but stop itself. So we're not relying on the motor home to slow and stop both vehicles. Cause let's face it.

Replacing the brakes on a motor home are expensive. It's going to have a pulley that mounts to the brake pedal arm. When you're towing the vehicle, when you apply the brakes in the motor home, the signal from the lights is going to pass through the cable, activate the system, in turn it's going to pull that pulley to activate the brakes. Again, this is a proportional system. So, depending on how hard you apply the brakes is going to depend on how hard the brakes are applied in the towed vehicle.

So again, it can slow and stop itself. Most of your braking systems are going to have breakaway switches in them or the second breakaway switch that's going to be added onto the vehicle. With this system, the breakaway switch is actually in the cable. So, if the vehicle comes disconnected and that cable pops out it's going to automatically apply the brakes in the vehicle. When you compare it to the other ones, as I mentioned, they have separate breakaway switches which have a cable and a pin that if those disconnect, it pulls the pin and applies the brakes. This braking system is going to be more of a permanent installation. So when you compare it to some of the other systems that are more permanent installations like the air force one, which is designed for motor homes with air brakes or the Stay-IN-Play duo which is designed for hydraulic brakes. The Stay-IN-Play duo and the air force one can be mounted anywhere on the vehicle inside or outside. So sometimes that can make it a little bit easier to install. With this one, the main unit has to be mounted inside the vehicle. So under a seat somewhere, even though they give you enough cable to run everything sometimes it can be challenging to find somewhere to put that so it's out of the way. That being said, this system can be used on a motor home whether it has hydraulic brakes or air brakes. Where the Stay-IN-Play duo is it can only be used on motor homes with hydraulic brakes, and the air force one can only be used on motor homes with air brakes. So this one gives you an option no matter which motor home you have. The installation process is fairly straightforward. The nice thing about this system is the wires coming off the main unit already have the connectors on them. The plug that you mount on the front of the vehicle already has connectors on it. All you have to do is route the wires from the plug to the main unit, plug everything together, route some wires up to your battery, grounds, and then run your cable to your brake pedal, and it's pretty much set up. When you have it set up like this, where this vehicle here obviously is raised up. It's got 37 inch tires on it. Our tow bar has to sit high because our receiver tube on our motor home sits real low. Obviously going to require a pretty tall high-low adapter. When doing that remember that the safety cables you're going to have to get extra long. These are actually 80 inch extension cables or safety cables, because they run through the tow bar and then they have to run down to the hitch. So just keep that in mind, if you have a raise vehicle and the receiver tube on your motor home sits low. Another nice thing about the braking system is it's going to come with a brake controller that mounts in the motor home. Brake controller is going to be just like any other brake controller. It's going to give you your pressure, if you want to apply more braking pressure to the towed vehicle, or if you want to load, a lower it it's going to have a manual override. So if, you know, it's going to work just like a regular trailer brake controller. The nice thing is, is it's designed for this system but let's say we don't want to take our Jeep with us somewhere, and we want to pull a trailer. We can still use that brake controller to work the brakes on the trailer in the same way we use them for the system. Now we've gone over some of the features. Let's walk through how we installed it. To start your installation, you want to mount your operating unit. It's going to come with self tapping screws. Typically the best place to put it is going to be right under the driver's seat. You just want to make sure that you slide your seat forwards and backwards and get it in the correct position so it's not making contact with anything. It's going to come with the self-tappers and they run right into the floor. Off of that, you're going to have four wires, blue, white, red, and a brown. Each one of those is going to have a connector on the end. Make sure you don't take those off. You're also going to have a cable. This cable is going to route to the front to connect to a bracket on the driver's pedal which we'll show you in just a little bit. How we ran these is you pop this panel off you take everything and tuck it right underneath and then we can put this panel back in place and it'll hide everything. After you get these, this panel off you get your cable kind of routed up. We're going to go up to the front of the vehicle and we're going to mount the switch or the plug that mounts on the front of the vehicle. Because the wires on the plug are going to have to route inside and connect to these. Next, you're going to mount this plug. You can mount it anywhere on your bumper. Make sure it's on a solid surface. Off it, you're going to have a yellow, green, brown, and white a blue, brown, and then a red that's going to have a black wire coming off of it. We'll start with the green, yellow, brown, and white. If you don't have a diode wiring kit installed installed, install it now. These four wires need to be connected to the dial wiring kit. This is going to come with a four-pole plug on it. You can cut the four-pole plug off and wire them directly together. They're going to be color for color, brown to brown, yellow to yellow, green to green. White wire, the only difference is, you're going to have a ground coming off the plug with a ring terminal. What I did is cut that ring terminal off the white wire coming from the diode wiring kit. You connected them together and they ran an extra wire and grounded it right to the frame rail. Red wire, I route it to that side and we'll get to that in just a minute. The black wire coming off it, the brown wire and the blue wire on this end, I routed it up behind the passenger side headlight right to here. I ran it through all this. You're going to have your red wire coming off of it. Gets connected to a fuse and then eventually attach to the battery, that you want to do last. From underneath, you're going to have a battery maintainer. It's going to have two red wires and a black wire owner. One of the red wires is going to be connected with the black wire underneath, as we mentioned earlier. The second red wire goes from here and connects to your fuse holder on your battery or the fuse holder that you're going to be connecting to the battery. This red wire, your blue and brown, you're going to route it up, across, and it's going to go inside the vehicle, which is going to connect to the wires coming off the operating unit. All I did was ran these three wires through these brackets, the factory brackets between this panel and the body across. I'll come back and I'll put wire loom on it after I'm all done. There's a grommet right down here in the corner. If you have an automatic, that grommet is going to be there. If you don't have an automatic and you have a manual that grommet will not be there. You're going to have to route these down, and there's a plug underneath the driver's carpet and the floor. You're going to have to route the wires up through that plug. Those three wires are gonna route here, and connect to the three wires coming off the unit. Off the unit, the white wire, you're just going to ground it to the body of the vehicle here. Typically you can find a body ground somewhere in here. If not, you can use a self Tapper with a ring terminal and just put it right in that side panel. For the cable coming off your operating unit, you're going to have a bracket with a pulley on it. It comes in your kit. We're going to mount this on the firewall in an area where this bracket that you'll mount pulls that cable straight back in the line straight line. What you're going to do is mount this bracket here, you're going to take this cable cause it's going to come long. You're going to run it through, get an idea of measurement of where you want that to be. So it's not pulling on the pedal. Mark it. You're going to pull it out, take this cable and slide it back through the sheathing or this cover. You're going to cut the cover, pull the line out, mark the line where you want it, and you're going to cut off the rest of it. So you are going to have to shorten this. They make it long, so if you wanted to, you can mount it under the back seats. You're going to have a little lock nut on there run your cable through it, through this bracket, and you can see how the brackets mounted, it's mounted a couple of nuts and bolts. Pull it through there. You want to make sure there's a little bit of play in this line, again, so you're not, the brakes are not being applied by the unit itself, have a little bit of play there. Then you're going to tighten that nut down on this cable. I'm going to make sure when routing the cable it's at a gradual bend when you have to bend it wanna make sure it's not a full 90 degrees. The cable's gotta be able to move through that cupboard. Once you get it in place, tighten these two nuts down on the bracket. Next, you're going to mount the pump. This pump can really be mounted anywhere. There's factory wiring that runs right here. It's running enough space that I just zip tied it to that factory wiring. Off that pump or in your kit there's going to be a plug for the pump. It's going to have your red and white wire on it. White wire is going to be a ground. Red wire is going to be for the power. The red wire that I spoke about earlier when we we're underneath, and I said to push it off to the driver's side behind the bumper, gets routed and connected to this red wire on this plug. Once you get those connected, you can plug that in. You're going to have some airline tube in your kit. It's going to have a couple of fittings with it. One, is for the pump side the other is going to be this hose. You're going to connect into the vacuum line coming off the brake booster. So you can see this line right here. It's a plastic one. Your kit's going to come with a T fitting. It's going to come with vacuum line. It's gonna come with a check valve. You want to make sure on the check valve, there's an arrow. Want to make sure that arrow is facing towards the engine. What you're going to do is you're going to make yourself a T. You're going to go from the line. You're going to cut it where you're going to install it. Install one of your clamps onto this hose or slide it on and take your vacuum line. Slide it onto the plastic line. These can be a little bit of a pain to get on. Spray some soapy water or something on there. If you have to take some needle, nose pliers stick it in there and spread that hose out, slide it on and then take this clamp and clamp it on that hose. Make sure you do not over-tighten this because it will flatten this hose out and you'll end up having a leak. You're gonna take the T fitting. You're going to put it into the other end. You're going to take another section of vacuum line put on the other side of the T fitting putting your check valve the correct way. Cause right now we're going towards the engine. On the other side of the check valve you're going to put another small section of vacuum line. Typically it's, you know, two to three inches long. Connect it onto the other side of the line that you would cut out, the section that you cut out from your factory line and then put on another hose clamp. Again, don't over-tighten those. Your line coming from your pump with this hose on it it's going to go right into the small end of the T-fitting. Put it on just like that. Basically what you're doing is the vacuum or the brake booster on the vehicle stores air. When we cut this line out, we're losing some of that air. We're basically making a fitting so we can include the pump into the same system. So when you apply the brakes on your motor home the pump kicks on and gives you enough air pressure to apply the brakes with the unit. Once you have all your wires connected, you go ahead and connect your fuse holder to the positive side of the battery, make sure the fuse is not installed. Once you have that on and tightened down you can install the fuse. This kit is going to come with a brake controller. It needs to be mounted in the motor home. It's going to allow you to control the brakes as you we're pulling it, as if you we're pulling a trailer. Now, if you decide you want to pull a trailer that has brakes on it, this brake controller can still be used to pull that trailer. On the back of the brake controller you're going to have four wires, black wire, red wire, white wire, and blue wire. Blue wire is a brake signal. It has to come from the seven pole. Black wire, is going to be your power wire coming from the seven pole as well. The red wire is going to be the signal coming from the brake pedal on the motor home and the white wire is going to be ground. Once you've got everything connected we can test the brakes. Now, if you've had this plug this dust cap plugged in here for more than three minutes it's going to take the system out of test mode. What you're gonna have to do is you're going to unplug it. You're gonna go up, and you're gonna pull the fuse, reinserted it. We're gonna put the dust cap back in. Then we're gonna pull it back off, should apply the brakes. Once you put it back in the second time it will release the brakes. Once you've tested the vehicle side test it with the motor home. How you're going to do that is, you're going to plug in the seven pole connector you're going to watch your brake controller. You want to make sure the red dot is in the corner. That's showing that you have it connected. Have somebody pull the seven pin from the towed vehicle side and you should see BA come up on the screen. BA means that you have a disconnect and it means the brakes are being applied. Once you've tested everything, you know everything's working correctly you can go ahead and reinstall your panels, button up any wiring that you want to cover up and you're ready to go. It's going to do it for look at and installation on the brake buddy stealth supplemental braking system on 2020 Jeep Wrangler unlimited..
