How to Install the Roadmaster Brake-Lite Relay Kit on a 2013 Jeep Wrangler


Speaker 1: Today on our 2013 Jeep Wrangler, you're gonna be taking a look at, I'm gonna show you how to install the Roadmaster Brake-Lite Relay Kit for Towed Vehicles, part number RM-88400.What the brake light relay is gonna do is, when you're flat towing your vehicle and you press on the brake in the RV, or you throw on the blinker in the RV, that signal's gonna transfer through to the towed vehicle. However, with your braking system in this vehicle, when the braking system applies the break in the towed vehicle, that brake light is gonna override the turn signal, which is illegal.What the brake light relay is gonna do, it's gonna allow you to only get your brake signals and turn signals from your RV while your Jeep's being flat towed. When your key is turned into the on position in your normal driving conditions, your brake lights are gonna function normally.So, you can see we have five wires here. We're only gonna be using four of them. Because our vehicle does not have a push button start, we will not be using the blue wire. So, we're just gonna cut that one off.

So, our black and our green wire are gonna go to our brake light switch under the dash, white wire's gonna be ground, red wire is gonna go to our fuse panel. One thing I do wanna mention with the red wire, you're gonna get a little bit of red wire. The fuse panel on this vehicle is all the way on the passenger side, so you will need to pick up probably another six to eight foot. You can find it on our website using part number 16-1-1.Next thing we need to do is, inside the vehicle, this panel right here in the center, underneath the steering wheel, we're gonna pull it off. You're gonna have two 10 millimeter bolts.

Go ahead and remove those. Pull up on this panel. We're gonna remove that panel too. If you look right here, this is your brake light switch. We've determined that this white wire with the brown stripe, this is gonna be our wire we're gonna be tapping into.

How we determine that is, with the key off, you can take a test light or a volt meter, if you poke the wire just enough, what we want is when we press the brake pedal, we want this light to come on. So, what we want, is we want the wire when we press the brake pedal, this is the wire that's sending our signal to our lights.So, what I'm gonna do is I'm gonna go ahead and pull this plug out. You wanna make sure you do not take the switch off, only the plug. To make it a little bit easier to work with this wire, take a flat head screwdriver, and it's gonna be hard to see right now, but there's little green tabs that you kinda gotta push on. See those green tabs right there And then we'll cut our wire.

inaudible 00:02:45 both ends.You take your crimpers, put your butt connector in there. It makes it a little bit easier to put it on the wire. We're gonna add one onto the side that's away from our switch. We're gonna add in our black wire on that butt connector. And our red wire, it's the one that's gonna go out through our fuse panel, I'm gonna add a butt connector on there. And then, my green wire, I need to add the red wire from my braking system monitor light that I have mounted on the mirror. So, we're just gonna put those two together. The green wire, with the red wire coming from our braking system monitor light, is gonna go to the switch side of our . or towards the switch of our . on the vehicle. So, towards the plug.Plug your switch back in. And then, I routed a red wire in. The extra red wire that's coming from your G-Force controller, you can use to extend this wire. You just wanna make sure that it's long enough to go across the vehicle to the passenger side. Like I said, if it's not long enough, we have wire on our website.And then, I'll go ahead inaudible 00:04:24 this in. If you look right here, our white ground wire, we can ground it right to one of these two. These are factory body grounds, so that works out well. So, because I'm gonna use this existing ground, our kit comes with a ring terminal. It's not quite gonna fit on there so I had to get a little bit bigger one, which you can find those on our website also. This wire's pretty thin. I'm gonna double it over because my ring terminal is bigger. Same 10 millimeter socket that we used to take the panel off on the dash. Now we can take all of our wiring here.So now what you need to do is we need to test our fuses to see which ones are hot when the key is on, and not hot when the key is off. So, right now we have the key in the on position. So, I'm gonna test this 10 amp fuse here. You can see with our key on, we're getting power. Now, we'll turn the key off. You can see we're not getting any power to it. That's what we wanna see 'cause that's what we wanna use.So, we're gonna pull that fuse out, like that. You're gonna have a fuse tap. That fuse is gonna go into the bottom. You're gonna get a fuse in your kit, it's gonna go on the top. My red wire, I have it ran through the same wire loom that runs across the firewall with my other wiring, so we'll go ahead and trim this down to size. Gonna plug that back in to the same spot and what we're probably gonna have to do, we're probably gonna have to notch our cover out just a little bit right here so our wire lays in there and doesn't get pinched.Once your install is completed, go ahead and put your panels back in place on the inside. Now, we're gonna test to make sure that our brake light relay is working correctly. With the key in the off position, we have it hooked up, simulating it being hooked up to the RV. What we don't wanna see is, with our blinker on, when we hit the brakes, from our braking system, pushing on our brake pedal, that brake light should not override this blinker. So, I'm gonna simulate that by pushing on the brake pedal and the blinker should stay on. Pushing brake pedal, we still have a blinker. So, our relay is working correctly and that'll do it, to look at, an installation on the Roadmaster Brake-Lite Relay Kit for Towed Vehicles, part number RM-88400, on our 2013 Jeep Wrangler.
