How to Install the Roadmaster Stop Light Switch Kit on a 2020 Jeep Gladiator


Clayton: Hello, everyone. Clayton here at etrailer.com. Today, we'll be taking a look at, and I'll show you how to install Roadmaster Stoplight switch on our 2020 Jeep Gladiator. Our stoplight switch is going to be one of the key components in our flat towing setup. We have our tow bar, our base plate, our diode wiring or supplemental braking system and our safety chains. Our stoplight switch is not visible from outside of the vehicle, and it's kind of hard to see inside of the vehicle.

But what it does is when our brake is pressed, it sends a signal to our indicator light. That way we can see it in our rear view camera on our RV. Located right above our brake actuator is our stoplight switch. This mounts to a bracket, which mounts to our dash. On our stoplight switch, there's a plunger that sits against the brake pedal.

When the brake pedal is not being depressed, that plunger is depressed into the stoplight switch.When that pedal gets pushed down, it releases that plunger sending a signal to our indicator light. As far as our install goes, it's really not that hard. We just have to make a couple of wiring connections and at our bracket. Speaking of installation, I'll walk you through how to get it installed now. To begin our installation, we want to make sure we have all of our wiring ran.

So that's going to be the wire from our operating unit, our G-Force controller and our indicator light. If you're using the Stay-IN-Play Duo, once all those wires are ran down here, we can then begin to install our stoplight switch. Our first step is going to be to remove our panel underneath our steering wheel. I'd like to start at the top because these are the thinner portions. You don't want to hang the entire bracket off of that.

As you can see, it popped out pretty easily. Now we can remove our screws down here and get our bracket installed.There's going to be two screws located right here and right here, this is going to use an eight millimeter socket. We can go ahead and take those off now. You can now grab our bracket. We're going to hold it up where we kind of want it and loosely install our screws. We will be using the same hardware. Once you have that semi tight. We want to look at our brake pedal. There's a ridge here in the middle. We want to make sure we're not putting our stoplight switch button on there. We wouldn't put it on a flat spot. So we'll slide our bracket over to where there's a flat spot, right about there. We'll do. And we'll go ahead and tighten these down the rest of the way.If you need to come back and adjust your bracket, feel free to do that. Just to get it centered perfectly. When we mount our switch, we want this button to be compressed. Then when the brake pedal lets out, it'll lease our signal to turn on our indicator light. So again, we want it mounted with this button compressed, and then when push the pedal, that'll release that button. We're just going to test this out and see where we need to stop our set nut here. I'm going to pull it back out and make our wiring connections. Just so we have a little bit more room. It does look like our bracket is pretty close to the pedal. So I'm going to start farther out and kind of get a good idea of where I'm going to set this back nut just to keep it compressed. And then I'll pull it back out like I said, to make our connections. Our kit is going to include a green wire and a red wire. It doesn't matter which way you connect these on here as long as they're both connected.We're going to strip these back and add some butt connectors. Give it a tug, to make sure our connection is not going to go anywhere. I'm going to wrap this up with electrical tape. I'm going to do the same thing for our black wire, With our connections made. We can now go ahead and put it in our stoplight switch again. We want to make sure not to move this because that we have it set to where that pin is compressed. Let me go ahead and do it, I will show you after I'm done. We now have our switch completely mounted. You do want to make sure it's not going anywhere so you can twist it and try to move it, in this case it's good. You press your pedal, you can hear the button moving and a good tip is you can take your cell phone, hold it underneath with the flash on and take a picture to make sure that that plunger is completely compressed. In this case it is, so we're ready to run out our wires.Our green wire is going to go out to power. So we're going to run it through that same hole in the firewall as the rest of our wiring. We are now ready to make our connections. We're going to be connecting our red wire from our stoplight switch to the red wire on our indicator light. And we're going to be tying our black wire from our indicator light into the black wire, from our operating unit and our G-Force controller. We'll go ahead and cut our red wire. We can leave it a little bit longer because there is a lot of room to hide our wiring because we have to come back. We can now add our butt connector provided. You can grab the red wire from our indicator light and put it into the other end of our butt connector and crimp it down as well. We need to extend our green wire. So we have enough room to get it over to our battery. I'm going to use a butt connector and another wire.We're just going to crimp this on here, but then I'm going to wrap this over with the red wire that we also ran to our battery for our braking system. I'm going to add a little bit electrical tape, just to ensure a good connection. With our power wire right over to our battery. We're not ready to cut our wire and at our fuse holder, we want to hold it down here and try to get the same distance as our other fuse holder. So I'm going to cut that wire right about here. You will have to buy a butt connector and a ring terminal to do this as it is not included in our kit, but it is an option to hook it up to our battery, instead of using a fuse. We can now add our butt connector to our wire. Now we can grab our fuse holder. We'll cut that right in the middle, strip back both ends. One end will go to our butt connector and our other end we'll get a ring terminal.I was planning on using a blue ring terminal, but since this is 12 gauge, I am going to grab a yellow ring terminal just because the opening is a little bit bigger for our wire. Now we're ready to hook this up to our battery and add our fuse. And everything hooked up, we're now ready to re-install our under dash panel. We're going to line everything up, then push it into place, now we're good to go. With everything else hooked up and our driver's seat put back in, we're ready to make our battery connection. We're going to grab a 10 millimeter socket and we're going to connect it to the farthest left post. Take our nut off, slide on our fuse holders, tighten our nut back down and add the fuses.With our fuses added, we're now ready to test it out. With our vehicle in tow mode. We can go ahead and pull our breakaway switch and see if our indicator light comes on and if our brake pedal's being pushed. Go ahead and pull it now. I can hear the actuator and we can see that the lights turned on. So that's pretty much going to do it for a look at and installation of Roadmaster Stoplight Switch on our 2020 Jeep Gladiator..
