How to Install the Roadmaster Stop Light Switch Kit on a 2019 Jeep Wrangler Unlimited


Ryan: Hey everybody, Ryan here at etrailer. Today on our 2019 Jeep Wrangler unlimited, we're going to be taking a look at and showing you how to install the Roadmaster Stoplight Switch Kit. So there's going to be a total of five main components needed to flat tow your Wrangler unlimited down the road. First one's going to be the base plate. So the base plate is going to be that solid connection point here at the front of your Jeep, which allows you to connect your tow bar to it. So that tow bar's the second component, and this is going to be that main link that connects the front of your Jeep to the back of your motorhome.

The third component is going to be, safety cables, and these are there in the event of a unlikely disconnect. The safety cables are going to keep your Jeep and your motorhome attached together.The fourth component is going to be tow bar wiring. So the tow bar wiring is going to transfer the lighting signals from the back of your motorhome to the back of your Jeep. That way other motorists will know your intentions as you're going down the road. And last but not least, the fifth component is going to be a braking system.

So what the braking system is going to do, is apply the brakes in the Jeep whenever you hit the brakes inside of the motorhome. And that's going to do a couple of things, not only is it going to make your stops more safe and predictable, but it's also going to reduce the wear and tear on your motorhome's braking system as well. But sometimes there's also smaller components that you need to use to make everything work together correctly and that's what the brake light switch is going to do.On your braking system, it's going to use a indicator light, and that light is going to tell you whether or not the brake pedal inside of your Jeep is being depressed. Except with the Jeeps, whenever they're in flat tow mode, the factory brake pedal switch is going to be inactive. And so you can't hook into that like you can on some of the other vehicles.

And that's exactly where the brake light switch is going to come into play. It's going to be an independent switch that hooks up to your battery and hooks up to your indicator light. And that's going to truly tell you if your brake pedal's moving whenever your braking system is activated. And one thing I really do like about using the switch kit is that we're not going to have to touch our Jeep's factory wiring at all. And to me, that gives me a lot of peace of mind, knowing that we're not cutting in or splicing into that factory wiring because these newer Jeeps can have really advanced and complicated electrical systems.And by not having to tap into that, we're not doing anything to jeopardize that factory electrical system.

So with this setup, it's one last thing you're not going to have to worry about and everything is going to work properly. So at the end of the day, a really simple way to get your indicator light to work. And that'll just make you feel that much safer as you're going down the road, knowing that your brake pedal on the Jeep is indeed being applied whenever you're stopping in the motorhome. Now, since this is a custom fit kit, it's particularly designed for your Jeep. So, that's going to make installation really straightforward. It already utilizes a stud underneath the dash that the Bracket Bolts do. And then you're just going to have a couple of wires that you need to run. So it's really no big deal. And shouldn't take you hardly any time at all.Speaking of which, let's go ahead and do that together now. To begin our install, we're going to be here on our driver's seat and we're going to be working in this area just behind our dash. Now, to make life a little bit easier, we can remove this center panel really straight forward, and just pop it off with your hands, kind of pry back on it and work it off and set that to the side. And just to give us a little bit more room, we can kind of push this up out of the way. We're going to have a screw Phillips head screw on each side, we'll loosen them up. And that'll let us bend this a little bit if we need to, have a little more room to see up in there. Now, if we look underneath of our dash, we're going to have a 13 millimeter nut, this one right here, and that's going to be located on the left side of our Jeep, so closest to the driver's side door. And it's going to be one of the nuts that is helping support our steering column here.What we're going to do is take a 13 millimeter socket and remove that nut. And that's where our bracket will eventually go, that holds our stoplight switch. So now, what we can do is grab our bracket, and one side of the bracket will have notches in it, the other side won't. We're going to take the side that does not have the notches, it's the side over here. We're going to take our switch, and just with the bolt nut on the threads there we got to feed it through like that. And on the back side, we're going to take the star washer and the hex nut. And we're just going to snug that down, just finger tight for now. Just loosely get it in place that way, if we need to adjust it, it'll be a lot easier to do so. So before we kind of put our switch and bracket in place, what I like to do is just connect our wires to these ends here. That way it's a little easier to work with, and we're not underneath the dash.So what we're going to do is carefully strip back the insulation. I think what I'm going to do is strip them back a little longer, so the wires are somewhat thin underneath that insulation. So, when stripping it back longer, I can kind of twist them together, kind of double it up like that. inaudible 00:06:46 that wire a little thicker and on each end, I'm just going to take one of the included butt connectors, slide that over. And then crimp it down. Do the same thing for this one here. And the reason I do this is, it's much more manageable to try to work with these relatively small wires on the open, as opposed to trying to lay on your back under the dash and do this. So once we have those connectors on, I'm going to take the green wire that comes included with the kit, strip back the insulation on one end and hook it up to either one of the black wires, it doesn't matter which side we go with here. And this green wire is eventually going to get connected to the indicator light that is on our braking system, so crimp that down.And then I'm going to grab my white wire. Now the kit does come included with a red wire and it's not long enough for how we need to run it. It fell about five feet short.So I'm using a piece of white wire that I had laying around, to replace it. So if you're going to end up routing this wire the same as me, which I do recommend you're going to need to get either a longer wire or a piece where you can then reconnect to the one that's included. I'd probably recommend maybe 8 to 10 foot of wire in here. With that being said, we're going to connect that to another butt connector. And this one eventually is going to run under the hood. And so the engine compartment over to the fuse block. But now that we have these connected, what I'm going to do is come back with some tape and just help secure them and clean up our install inaudible 00:08:56 a little bit. So I went ahead and taped up our butt connectors there, and that's what it looks like. Now, we're going to take this whole assembly here and put it back up underneath the driver's side dash. And so how this is going to work is, this is going to set this way.The switch part is going to kind of get pushed against our brake pedal arm. And this hole in the bracket is going to go over that stud, which we removed that nut from earlier. So then we can line up our bracket with that stud, push over to the top and then take the nut and inaudible 00:09:38 it. So as you can see, this is how our switch is going to sit. It's going to be in line with the brake pedal arm. That way, whenever we push your brake pedal arm down, it's going to initiate that switch. And we are going to have to adjust that, but we'll get our two wires hooked up and then we'll be able to test it a little bit better to make sure that we have it adjusted correctly. So our green wire, that's going to get hooked up to our indicator light. Now, in our case, we're using the Demco Stay-IN-Play breaking system, and so we're going to hook the green wire up to the red wire, to that. If you're using a different braking system, the color of your indicator lights wiring may be a little bit different.So just make sure that you see those instructions and that'll let you know what, why, you need to hook up more or less. And so I'll just slide that green wire into the butt connector and crimp it down. Now the white wire, what we're going to do is run that into the engine compartment, then hook it up to a power source. So we did pass it through the firewall. And right here in this area, just up higher, there is a grommet that we used to to be able to do that. So this is a little bit better, look at that grommet that we pushed our white wire through. So underneath the hood now in the engine compartment, here is the grommet that we ran our white wire through. And we're going to run this over to the passenger side, to the battery. So what I did is just loosely followed our firewall here, all the way across, over to the battery. And then once you got everything hooked up, you can always come back some zip ties and tape and clean everything up.So here's where our white wire ends, and what you're going to do is attach it to the included fuse holder. So same thing as the wiring inside, just use a butt connector to connect those two together. And on the other end, you're going to take the included ring terminal and crimp that on. You then want to open up the cap and make sure that the fuse is not installed yet. So we're empty, so we're good. With that, hang out for a minute. You come over here to your positive battery terminal and lift up the cap. We're going to remove one of these nuts, and I'm going to take this one off here. So I'll grab a 12 millimeter socket, strike that loose. I'll completely remove the nut inaudible 00:12:30 you take a ring terminal, and slide that over the inaudible 00:12:39.We'll just take our nut and snug it back now. So now that we have it connected and kind of put our cover back over, leave it back up to our fuse holder, take the included fuse, and push it into place. So now back underneath the dash, what you're going to need to do is adjust your switch. And so, how you want this to work is, the plunger on the backside of the switch that sits up against the brake pedal harm, you want that to be fully depressed whenever the brake pedal arm is in that relaxed position. But whenever you start to push down on the brake pedal arm and get a little bit of movement after, I'd say, about an eighth of an inch of that brake pedal arm travel is where you want that plunger on the switch to start to come out. And once that plunger on the switch starts to come out, that's when it's going to send power to your indicator light and eliminate it.So the way to adjust it is the nut on this side. And if you remember, we had another nut on the other side of this bracket, you can either loosen them or tighten them, and that's going to make this switch pull further away or push closer to the brake pedal arm. And once you find that sweet spot, you're simply just going to tighten the nuts down, that way the switch is secure. So I went ahead and resecured this here, and now we can say our panel and just push it back in place. And that'll finish up our look at and our installation of the Roadmaster Stoplight Switch kit on our 2019 Jeep Wrangler Unlimited..
