How to Install the Roadmaster InvisiBrake Braking System on a 2014 Jeep Wrangler

Speaker 1: Today, on our 2014 Jeep Wrangler, we're going to be taking a look at and showing you how to install the Roadmaster InvisiBrake Supplemental Braking System. Part number, RM-8700.Now, this is what our InvisiBrake looks like when it's installed. You can see it doesn't take up a whole lot of room. Now, this is going to be a more permanent application. There's not going to be any on and off switches. So, as soon as you hook up to your RV, it's going to be ready to go.

It can be easily mounted, as you can see here. Customer wanted it mounted in the back. Or it can be mounted under the front seat. Now, you can use this system with RVs that have air brakes or non-air brakes. It'll work with both.Now, here on your driver's side, you can see how little space it takes up.

The only thing you really can see is the pulley system that is attached to your brake pedal. Whereas, some of your other systems, you would have a big box that you would have to take out of your vehicle and put back in when you wanted to use it. All of your wires are hidden underneath your panels, underneath your carpet; and again, you don't have any on and off switches, so once you get to your destination, you just unhook your vehicle from your RV and you can use your vehicle normal.So, now we'll show you how the InvisiBrake system works on a pedal. When the brakes are applied in the RV, it applies the brakes inside your towed vehicle at the same time. Now, you're going to have an adjustment knob here and a pressure gauge.

This is going to give you the correct pressure for towing your vehicle. Now, you're going to want to take your RV down the road a few times and test out to see how much pressure is on your brakes and if you need to adjust it, this is where you're going to do it.Now, all of your power from your InvisiBrake is either running through your battery or running down to your 6-pole down here and then you have your umbilical cord, which is running over to the 7-pole on your RV.One good thing about this system is that while you're in tow mode, you're towing the vehicle, it will actually trickle charge your battery. Now, in the driver's seat of the RV, when you're towing your vehicle, you'll have an indicator light that's going to tell you when the brakes are applied in your towed vehicle.So, the first thing we need to do is we need to mount our control box. Now, the customer because he intends on taking this Jeep off-roading and he's got kids that climb in and out of the back of it, he doesn't want this put under the seat. So, he decided he wanted it mounted in the back of the vehicle.So, what we're going to do is we're going to mount it about right here.

So, the good thing about these is these can be mounted anywhere. You could mount it up against the back of the seat if you want. It can be mounted upside down. So, it doesn't necessarily have to be on a flat surface.The next thing we do is we need to figure out where to mount our cylinder. Typically, they would go under the seat, or in the back seat under this panel. If we put this here . because this is a two door, if we put this here we're going to have a lot of extra wire that's going to be pulling on the brake and what you don't want to do is you don't want this twisted because this is a metal wire. So, we got to try to mount it back toward the back a little bit farther.So, what we're going to have to do is we're going to take out this seat. It's going to give us a lot of extra room to work. Take your screwdriver and this is just a trim panel tool, pop off that cap. You're going to have one here and you're going to have four bolts to mount. You're going to have two here and you got two in the back and it's possible you're going to have some wires underneath with some plugs you need to unplug. We're going to be using and 18 millimeter socket.So, now we're going to have another cap under here. You're going to pull it off the same way and then even though your bolts access . you can access it here. It's a little hard to get this inside, so what we're going to do is we're going to take that out. We're going to be using a T25 star bit and we're just going to remove this screw right here. So, now we'll take a short socket because we can't get our drill down right here. We'll take a short socket, 18 millimeter again.This plastic piece off, there's another star bit right here on the front. Then we'll just pop this panel off here.If you notice, there's not a lot of room here to get to this bolt. On a Jeep, if you push the seat back, pull the lever on the side of the seat itself and that allows for your passengers in the back to be able to get in. Now, we can go straight down on it.We're going to have one plug here on the bottom of our seat. We're going to unplug that and then we can remove our seat.So, what I did is I found a location for my cylinder under this center panel toward the back. Now, as you can see, I've got this line where it's going to run underneath the drivers seat and this is going to give me an idea of how much I'm going to have to mount my wire here, or my pulley, on the back of my brake. So, this is going to give me a general idea. So, what I'm going to do is I'm going to take my two for my bracket. This is going to hook to my brake pedal here. I'm going to measure it out to see what I'm going to need to remove.So, what I'm going to do is I'm going to take this part here, this is going to be where my brake pedal arm is going to be laying on the back like this; and what it looks like is this very first hole here and this hole are going to be the only two holes that I need, so I can actually cut off the rest of this; and I'm going to do that on both of these.I just used a grinder with the cutting wheel and cut off what I needed to cut off. Now, with this bare metal here, even though it's going to be on the inside, with your foot being up there, it's still susceptible to rusting and getting wet from the elements. So, you can paint. Take some paint and paint it. I happen to have a black paint marker and I'm just going to go over this bare metal with a paint marker, just to cover it up.Now we'll take our two brackets and our two bolts and we're gonna put it on our brake pedal like that. And what we're gonna do is we're gonna snug these up. We don't wanna tighten them all the way so that we can adjust it once we get our wire and everything hooked up.Next we'll take a 10 mm socket and our V-4 allen wrench, and we're gonna snug these up. Our little bracket that's going to our pulley, slipped onto our wire, we're gonna take this bottom nut, and we're gonna take it all the way off. This one, we're gonna go down about half way on here.So, we'll take our wire, feed it through. Take our nut, put it on. Take our other nut that we took all the way off, and we're gonna tighten it on the back side of the nut. So where we're looking here, is where we mount our pulley, we want to make sure that this here, when the pedal is depressed, doesn't hit the pulley. So we're gonna have to mount it a little bit off to the side. I'm almost thinking that maybe this way, because out wire's running over this way already, that this side might be a better place to go. So what we're gonna have to do is we're gonna have to cut a slit in the carpet, and mount this to the metal.So now we have a general location of where our pulley needs to be. We're gonna take this back off. I'm gonna pull my floor mat out. Then I'm gonna move my carpet. Now, this being a jeep, this is fairly simple. You have a little plastic fastener here that just screws on. We're just gonna peal this back, and we're gonna have two of the same plastic fasteners up underneath, along the firewall.We'll just set this out. Out of our way. So now we'll hook our pulley back up. I think we'll put it right there. And the rest of this, I think can get tucked in underneath of here. One of our self-tapping screws.Now that we got a good spot, go ahead and put in our other screws. Show you how it works.Next we're gonna take two more of our self-tapping screws, and we're gonna take this little bracket right here, and that's gonna hold down the end of this, because this wire needs to come straight out of there. So we're gonna take this, and if you look at the end, this fits right on there like that. We wanna have just a little bit of slack in our line. Just enough where that ball moves, because if it's too tight, your breaks are gonna be on all the time, and you don't want that. So you want a little bit of play, add a little bit of extra. When I lay my carpet on, it's gonna pull that tight enough.Looks like a good spot to mount it. I'm just gonna take a paint marker, that way if it happens to slip out of the way, I know where my spot is. And I'm just gonna mark the top. Line it up with those marks. Take one of my self-tapping screws.So now what I'm gonna do is I'm gonna peel back this carpet, peel it back from under the back seat here. And take my small airline tube, and you can see the end here that is twisted up, I'm gonna save that for the back, because I'll need to cut some off. I'm gonna take this, and I'm gonna feed it inside here. Airline tube here, straighten it out. And we're gonna run it under the carpet, right back to the back.What I did is, I just had some bigger airline tube that I had laying around the shop, just gonna run it straight under my carpet, right up to the front, or to the front of the backseat.And then I'm gonna run to the back, I'll put it on the inside of this. I'm gonna take some electrical tape, I'm just gonna throw a little bit of tape on there just to hold it while I pull it through. And we'll go to the back, and pull it through.Seat down. There you can see my airline tube is pretty much hidden. I can tuck it down under this if I want to. My break box is gonna sit right here. This is gonna run in through the back of it. You can see here this is my airline tube. I'm gonna make sure I give myself enough that it's not gonna get kinked up. And if I keep it toward the center here, nobody's feet will be on it. I'll go ahead and lay my carpet back down. Make sure we have a nice fit for everything.And take our quarter inch airline tube and you're gonna have part of a rubber hose in your kit, you're gonna put it on one end, and the other end is gonna go on the back of your control box on this big spot here. I'm not gonna hook it up yet, because once you hook it up there, it's pretty hard to get off if you need to get it off.So, now I'm gonna go back, and I'm gonna fold my seat back forward again. And for this line I'm gonna try to run this one along the side panels up to the front, and there's a rubber grommet up there on the firewall, that we're gonna try and get to. So we're gonna run this one different than this one.So I just wanna give myself a straight line to run my quarter inch. Now, I'm just gonna tape this on here, and we'll pull it through. I just set my rubber hose, just kind of pushing on it just a little bit. Just enough to hold it. And I ran it behind my seatbelt, now what I'm gonna do is I'm gonna lay my seat down. I wanna make sure that I'm not pinching my line here with any part of my seat when it tips down here.Go ahead and set it in place. Put pressure on it, that way it kind of simulates somebody sitting in the seat. And we can see that we have room here, so we don't have to worry about pinching it.So now we're gonna pull out these here, so we can run an airline tube underneath of it. I'm just using a trim panel tool here, just so I can get enough grip on it to pull it with my fingers. Take my airline tube, and I go underneath. I'm gonna run it right through here. I'm gonna follow these existing lines.So now let's take the rest of it, and run it up like this, and go ahead and put this back in place, and start with this one. And then we'll just replace our fasteners.Now what I did was I took my red airline tube, and I ran through a grommet that's up here that you're not going to be able to see. What I'm gonna do is I'm gonna take my airline tube that I'm running back to my brake controller, and I'm gonna tape it on here, and I'm gonna pull it up through the rubber grommet.So what we're gonna do is you can see our brake booster here, and our lines coming out of it, and kind of wrapping around and going up. So what we're gonna have to do is we're gonna have to cut this, and we're gonna see what size our hose is.Now, up here on the line, there's another check valve, so what we need to do is we need to stay in between our booster, and this check valve. Once we cut the line, we're gonna figure out what size hose it is, and we're gonna have two different size . we're gonna have a T and a check valve. This is gonna be for the smaller size hose, and you'll have one for a larger size hose. We just need to see which one we're gonna use.So what I'm gonna do is I'm gonna cut it right in this straight area here.So now we'll take our T connector, and we'll push it inside the hose. So now my airline tube that I ran up here from my box is gonna go right there on the end of that T. So I'm gonna go ahead and cut this off. I'm gonna be using airline tube cutter, you don't wanna use pliers, because what it's gonna do is it'll pinch this, and if you pinch it, then it's gonna reduce the air pressure going through there, and then your equipment may not work correctly. However, you can find one of these on our website, part number AL10530.You wanna make sure you got it nice and flat, it's not pinched or kinked. Now you're gonna get a quarter inch piece of tubing, and we're gonna go ahead and cut that in half. We're gonna take one end, and go onto our hose here. And this end, will go onto our T, like that. So our other half, is gonna be on the other end of our line, it's gonna go into our InvisiBrake System.So now what I'm gonna do is I'm gonna take my check valve, and it's gonna have arrows on it, and it's gonna tell you which way your airflow goes. From the brake booster the air flows this way. This line goes toward the engine. Push that into place, then we'll get our other end, and put it into place, like that. Once we get all that back together, we can zip tie all this back to the line again.Next we're gonna take our breakaway switch line, which is gonna have the plug like this on one end, and on the other end . you're gonna have your plug which goes to this, and you're gonna have a red and a black wire. We're gonna route them to the front, but first we're gonna take this and we're gonna plug it into the correct location on the back of our InvisiBrake control box.We're gonna get our general area, and then we're gonna route all this up to the front, under the driver's seat. Take this and get it underneath of our carpet. And now we'll take . while we're here, we're gonna take our brake signal wire, those are our taillights, our running lights and our ground wire, we're gonna go ahead and hook it into the back of our box here. And we're gonna route it with our other wires.What I'm gonna do is I'm gonna drill a little hole here in the firewall, just big enough for this grommet. Then I'm gonna run all these wires through that hole. The reason I'm doing that is because if the rubber grommet that he's got in the firewall up top, he uses this for an offroad vehicle occasionally, so he's got a lot of stuff that's running through there already, and I don't think we're gonna get all this to go through.So we're gonna take a step bit, and I'm just gonna go one size at a time until I get that grommet to fit in there. This grommet is not included in your kit, so what we did is, this grommet actually comes one piece. What we did is we slice it open, and put our wires inside of it, and you're gonna make sure that this lip is gonna be on the inside of the vehicle. So I'll push that down, and I'm gonna start feeding my wires through the hole.Where I ran through my firewall, went out behind my wheel well, what I did is the same thing I did before, I took an airline tube, ran it straight down from here, down to where my wires we're coming out, and I just reverse pulled it out, and it pulled all my wires right here out the top. And once I get everything stretched out, I'm just gonna find a way to route it, and I'm gonna follow this line here, find a way to route it through here, to do what I need to do on the front of the vehicle. Gotta have my power wire, and my ground wire, because that's gotta run over to the battery.I went ahead and ran my wire over top of this one, under here, and I got it to fit underneath here. Now what I had to do to fit this end through this corner is I just had to kind of shave it a little bit. Just enough to get it through there.So now what we're gonna do is this wire that's already bundled up, is going to a 4-pole connector that's coming out the front of the vehicle. This one here is the one that's hooked up to our InvisiBrake System in the back. What I'm gonna do is I'm gonna tie this into that, and we're gonna cut all these in half. Go ahead and split these, and then we're gonna take our wire that's running from our InvisiBrake, go ahead and cut it off, go ahead and get our wires here, and then we're gonna take these and we're gonna match up our colors. And we'll take one of our included butt connectors, put it on one end, clamp it down. And we're gonna do that with all our remaining wires here.Now what we're gonna do is we're gonna connect all these into our color matched ones. The only thing we're not gonna do yet is we're not gonna do the white one. We actually are going to splice in another ground.So now we're gonna take this, tie it on here, and it's gonna go into the other end of out butt connector from our other two white ones. So we'll take our boot and ring terminal, and now what I'm gonna do is I'm gonna go ahead and wrap this electrical tape and take all this and kind of bundle it up here.We'll take one of our self tapping screws . now you just want your ground tight enough that it's not gonna move. You don't want it so tight that you break your ring terminal off.As I got my box set up here, and I close my door, to make sure this wasn't gonna hit my door, and my door would close fully. And I took a pink marker, and I marked the spot there. So now I can move this, put my bolt in there. Now you see how these are, I'll be able to slide it right on, and then tighten my bolt down.We'll take one of our self tapping screws, and slide our box into place. Go ahead and put one in here. And our box is in place. Now go ahead and hook up my quarter inch airline tube, it's gonna be going in my second hole here, and we wanna push it on. You can see, it's not gonna come off, and we can take our smaller airline tube, and it's gonna go in this spot, but we need to cut that down a little bit. And we're gonna take it, and we're just gonna push it into the hole. Nice fit. Now we can put all of our stuff back in back here. Now keep in mind, these blue wires here, they don't have anything to do with the InvisiBrake, these are two a speaker box that the customer had in the back of his vehicle, we just removed it to give us a little more room to work.So for our break away switch, as you can see, this customer has an after market bumper, he uses this jeep for off roading, a little bit of rock climbing, and we didn't want this break away switch to get tore up. So I took a long bracket, and modified it. Now you can find one of these long brackets on our website, part number 18136. What I did is I modified it so it will sit inside the bumper here, and it will be protected by everything.So this is how I did it. And it's gonna sit right there. Now we'll put our hose clamp on, and you can use a socket, I'm just using a flathead screw driver. And we'll tighten it down. Then we'll take our plug from our break away, but you can see I just routed it right down next to the four-way plug that was there. I'm gonna route it down inside the bumper here, and my plug is actually right back here. Just push those two together like that. I'm gonna go ahead and take this up, and then I'm gonna zip tie it, and I can drop it right down inside of this bar here. And we'll just go through the hole here, on the under beam of the bumper.Now in you kit, you're gonna find a long black wire, it's gonna have a female end with a plug on it like that, and the other end is gonna be cut off. This is the wire you wanna use, and what we're gonna do is we're gonna splice it into this green wire that's coming off of our break switch, and it's gonna go up to our 6-prong, which is gonna tie into the camper, or the RV. And then we're gonna splice this in with the black wire. This end of our green wire, we're gonna take one of our included butt connectors, it's gonna be the blue one, and then we're just gonna put these two wires together.Since this is gonna be connecting directly into our 6-pull, we're gonna cut this off. And we're gonna fee it through our grommet, where we ran all of our other wiring through here. So you can see here, the break switch wire that's coming through my carpet, part of my carpet is not going in all the way, so I'm gonna have to splice this down, and then we have our pulley underneath, we're gonna slice it down here, get our distance right, and then we'll open it up just a little bit more for our pulley.So once I have my carpet back in place, and everything set up, I can go ahead and adjust this here. Get it tightened where I need it to go, because we want this pulley to pull this straight back when it's being used. We can go ahead and start putting our interior back in place. We're just gonna go in the reverse order of the way we took it out.So now from here, we look at the back of the 6-pull, it is actually marked where your wires go. Take the black wire that was running to our break switch inside the vehicle, and we're gonna put it into the spot on here marked with the A for auxiliary.Next we're gonna hook up our power wire that's running back to our InvisiBrake. So we'll just splice both of those. Split them in half. Now we're gonna take our fuse, we're gonna split it in half, and then open up both end, put our butt connector on one end, and we're gonna hook it to the other side of our positive wire, and we're gonna hook our ring terminal on the other end. We're gonna wrap that with some electrical tape, and we're gonna cut down our ground wire.Now we'll take our two millimeter socket, hook up our negative wire here. Now to hookup our positive. Now you wanna make sure you don't insert your fuse yet. Since that one came off, we're gonna go ahead and take this off. The reason for that is, you don't want any back feed going into your lines, and causing a problem with your wiring. Now we can insert our fuses.So now we're gonna activate our InvisiBrake, and it's gonna put pressure on our brake pedal, if for some reason the vehicle is detached from our RV. Now we don't have an RV hooked up, so what we're gonna do is we're gonna pull our breakaway device here, which is gonna activate the brake. All we do, we're just gonna pull that out.Next we're gonna run our light into our RV. What we did is we came through the engine compartment here, and I found where some wires are running in underneath the dash, took some airline tube, pushed it through the hole, and then connected my 50 foot section of wire, and it's gonna have one end, the female end on it, and the other end's gonna be open. And I put it in the end here, and I'm gonna go in the RV, and pull it in and get what I need. Rather than taking the whole bundle and trying to feed it through this hole out, come outside, push it in.So now inside we'll just pull our airline tube through. So now what we're gonna do is we're gonna strip the end of the wire here, and we're gonna put a butt connector on it, and then next we need to find a place for our light.So now we'll take a five-sixteenths drill bit . you wanna make sure that there's nothing on the backside, no wires or anything that you're gonna drill into. And we can test fit the light. Make sure that it's gonna go into place. Now we can take our included sticker and just put it over the hole.So next we're gonna take our circuit board audio signal, and we have a red and a white wire, from the back of our light we have a red and a white wire, we're gonna take these two, connect them to the proper color, and put a butt connector on them.So now we're gonna take our black wire that we ran into the dash, and we're gonna hook it into our red wires. Now because our ground wire was so short coming off the back of this, I couldn't find a spot that was close enough to ground it, so alls I'm gonna do is I took some more white wire, and I'm gonna extend off of this to give me a good ground. I'll put a ring terminal on one end. You can see here this is where I found would be good to put my ground wire, and then up right behind the light, I just bundled my wires up, and zip tied them to some existing wiring that was there.This is my power wire that's running from my light in the front. You can see my 7-pull here. I'm gonna hook it up to the center there, so it matches my vehicle.Now our red light that we put in our dash here, when that light comes on, that's indicating that our brakes are being applied to our towed vehicle in conjunction when our brakes are applied in our RV.And that'll do it for the Roadmaster InvisiBrake Supplemental Braking System part number RN-8700, on our 2014 Jeep Wrangler.

Reply from Les D.

To flat tow your 4X4 Wrangler (with factory bumper) you will need a base plate kit like the Roadmaster # RM-521453-5, and a Roadmaster # RM-522 tow bar, and Roadmaster # RM-154 wiring kit. You will need a supplemental braking system like the Demco # SM99251 "Stay-N-Play Dou."
