Video Transcript for Roadmaster Even Brake 2nd Vehicle Kit Installation - 2013 Jeep Grand Cherokee

Hey, everyone Shane here with Today I have a 2013 Jeep Grand Cherokee. We're gonna walk through how to install an Even Brake 2nd vehicle kit. The second vehicle kit is gonna be designed, so that if you have the even brake already, you already have and even brake and you're planning on towing a second vehicle within your family. You could even brake second vehicle kit allows you to use that main breaking system in each of the vehicles. One thing to keep in mind is depending on which model even brake you have will depend on the kit or the second vehicle kit that you would need.

There's going to be two kits. If you're even brake has a black wire, it's going to be, it's going to need one kit. If your even brake has a blue wire, it's gonna need a different kit. So make sure when you're hooking it up, look at the serial number that's on your even brake setup and use that serial number to get the proper kit for your second vehicle. As far as the installation process, pretty simple and straightforward.

It is gonna require for this vehicle, it is going to require a 12 volt outlet, for the braking system, because for the 2013 Grand Cherokee does require the battery to be shut off, which shuts off all power to any 12 volt outlets that are currently on the vehicle. You can find those here at etrailer. The second vehicle kit is gonna come with your breakaway switch and your tether as well as the cable that go from your breakaway switch inside to the transmitter. Keep in mind, running the wire from the breakaway switch inside the vehicle is not really a good way to do it. There's not really...

Grommets or factory wiring that are easy to get to. So, I found the easiest way to do it is on the passenger side. If you pull down the cardboard panel, right up in the corner, you'll see the power wire coming from the battery outside to the jumpstart post that's on, on the passenger side, under the hood. Right above it is all open, drill a small hole. And that's where you can feed your wires through.

Now we've gone over some of the features. Let's walk through how we got it installed. Start your installation. As I mentioned earlier, it's a good idea to have the fascia removed. It's gonna make it a lot easier or do it while you're installing your base plate. Your ICX transmitter is gonna be have to be mounted on the driver's side, so that the cable coming off of your braking system can plug into it. The green wire that's coming from your stoplight switch is gonna plug into the male spade connector and number one. So if you look on the opposite side where you have the red or the power and a ground wire, there's going to be a male spade connector there. The green wire coming off that is going to have to plug that again, power and ground. I routed these straight underneath the dash here, the center console, because my battery is underneath my passenger seat. Ran them underneath the carpet, and then added a ring terminal and then mounted them on the positive side of my post. And then I grounded the ground wire to the side of the, the battery compartment with a self tapping screw. Breakaway switches here. It's gonna come with the mounting hardware, your base plate, it's gonna have a bracket that you're gonna install during the base plate installation. That gives you a hole to mount your breakaway switch. And then all you have to do is run your cable. The cable that was inside is one piece, that has two, a plug on each end. One end is gonna plug into your breakaway switch. The other end is gonna plug into your transmitter. How I ran mine was from here, this factory wiring on our bumper beam, straight across. I zip tied it all the way here, went straight up behind my, past your head light, to here. And then inside the vehicle. You have, the power wire that runs right up to here, right up above it I drilled a small hole and I cut one of the plugs off, left a little bit of length, cut the end of the plug off. So that I only had to drill a small enough hole, or a big enough hole to get the wire through. And then I re-spliced the plug onto the end. Very simple it's going to have black and white wire in it, just connect the two back together once you're, once you've got your wire through. Now that we're in. All we have to do is mount the unit, up underneath the dash. We're gonna have a wire that we need to route from a brake light switch over to hook into it. And then your power and ground. Your kit is gonna come with a brake light relay. However, on this vehicle, we cannot use the relay because you can't tap into the factory brake wire. So we had to put a stoplight switch on it. A Stoplight switch is gonna have two wires coming off of it. It's gonna come with a green wire and a red wire to attach to one of those two wires. A red wire is gonna be full power. Green wire is going to be routed over to wherever you mount this. And you're gonna add a spade connector and it's gonna plug in right there. The other two wires on this unit, are gonna be your power and ground. This is gonna be for your breakaway switch. We can go ahead and plug in our breakaway switch. Just like that. We're probably run some tape around that just to make sure that it doesn't come disconnected. And then because our battery is underneath our passenger seat, I went ahead and extended my red wire and my white wire, because what I'm going to do is I'm going to route the wires underneath the carpet, along the inside edge and then over to the battery. Once we get to the battery, we'll have a fuse, fuse holder, add onto the positive side of the battery, and then basically put everything back together. We're gonna go ahead and extend my white wire as well, as I mentioned, I got my wires running underneath the carpet to my battery compartment here. And the way I did it, is I just used an airline tube that I had laying around. You can use wire hanger, anything that I'll go from here down into the box. I cut my white wire down, added the ring terminal. I'm just gonna take a self tapper and go right into the side of the box, in the sidewall and mount my ground. Added my fuse holder to the end of my red wire, ring terminal on the end, we wanna make sure that our fuse is not in the holder. When we attach it to the positive side of the battery, once we get it attached, we can go ahead and insert our fuses and make sure it's turning on. Once you have everything hooked up in the Jeep. You're gonna take your braking system, your even brake braking system, and it's going to have to be programmed to the new transmitter. Those instructions should be in your manual for your braking system. Next, we're gonna test out our system with our transmitter. I have my monitor for my motor home plugged in here. I don't have the pattern, the power completely disconnected here in the vehicle, just so I can test it out and make sure it's working together. There are blue wire coming from our braking system, plugged into the port on the bottom of the transmitter. We'll take our 12 volt plug for the system. We'll plug it into 12 volt outlet. We're gonna hit the test button. And what our system is doing is actually building up air pressure inside of the unit. You can see we've got a green light on our monitor for a motor home, it says testing is good, system is ready. We're all set up. Once you have all that done, you're ready to go. To look at and installation on the Even Brake 2nd Vehicle kit on a 2013 Jeep Grand Cherokee..

  • Does ICX Transmitter Box Need to be Connected for Roadmaster Even Brake System
    Yes, the ICX Transmitter that comes with the Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 is essentially the brains of the unit and you even plug the breakaway pin to it so the Even Brake will know to apply the brakes if your towed vehicle becomes unhitched. This is justified further by the need for a new one if you use the Roadmaster Even Brake 2nd Vehicle Kit # RM-98450. Attached is a review video and the installation instructions for you to check out.

  • Replacement Supplemental Braking System for Replacing Roadmaster RM-9400
    If you are missing the main assembly that sits in the floor board of the tow vehicle and applies the brakes you'd need to replace basically the entire kit since the second vehicle kit does not come with that. Since the RM-9400 was discontinued you'd be best served with the Blue Ox Patriot part # BLU37TR instead which is the best performing and easiest setup for this type of supplemental braking.
