How to Install the Roadmaster Even Brake Portable Braking System on a 2013 Jeep Grand Cherokee


Today on our 2013 Jeep Grand Cherokee, we'll be installing the Roadmaster Even Brake Portable Braking System, part number RM-9400. We're going to use the Roadmaster Stoplight Switch Kit, part number RM-751449. Part of this system is installing a breakaway switch, which we're going to start with. We'll move to front of the vehicle, locate a suitable spot for our breakaway switch and then mount it using the hardware provided. Here's what our brake switch will look like in the stored position, then when in use, we'll simply just rotate it out towards the tow vehicle, hook on our cable and then attach it to the tow vehicle and we're ready to go. Next, we'll plug into our 2 wire cable provided with the breakaway switch.

Next, tape up this connection point. Keep the 2 connection points together, clean, free from dirt, dust, debris, or moisture. Take the other end of our wire and then I'll feed it in the fascia. We're going to route it and follow the 4-pole wiring harness that's been previously run towards the firewall and, ultimately, it's going to go into the cabin of the vehicle. Now, to get our wire inside, we're going to use the manufacturer's grommet. To gain access inside of the manufacturer's grommet, we'll need to remove our kick panel.

To remove the kick panel we'll first need to remove the threshold which we'll use our anterior trim panel tool or a flat-bladed screwdriver to get underneath, pop it free from the fasteners that hold it underneath. With the threshold out of the way, we're going to remove the kick panel here on the driver's side. I'm just going to get behind it and release the fasteners underneath. Next, to give myself some working room, we're going to pop the wiring harness off of the sheet metal. You'll remove a push pin fastener here near the threshold.

Next, I'm going to fold the carpeting back. We'll grab it up past the parking brake pedal, roll it down and out of the way. Next, we're going to peel back the plastic liner. It's simply held in with some spray foam to open up the access panel in the inside door pillar. The door pillar is filled with a spray foam. We're going to remover the grommet on the outside of the door pillar, push a screwdriver through the foam.

Now we can follow our pilot hole made by the screwdriver with a drill bit to clean out enough of the spray foam to get our wire through. With our hole created, we'll go ahead and take the wire that we've routed from the front breakaway switch and route it into the vehicle. To assist in getting our wire into position, we're going to use a pull wire which can be a stiff piece of wire. In this case, were going to use a piece of air tubing. Now we've got our wire pulled out, we're going to go ahead and prepare the grommet so we can route the wire through the grommet. We're going to simply just cut open the grommet large enough we can feed our wire through it, pull the grommet down the wire, and then feed our wire into the cabin of the vehicle. Once we have enough wire inside, we can then just go ahead and re-install the grommet. Now we've got it routed inside, I'm going to go ahead and follow the manufacturer's wiring harness and secure it as necessary. Now with my wire secured, I'm going to go ahead a re-install the anterior paneling. Next, we're going to remove the under dash cover. There are 2 plastic push pin fasteners we'll need to take out, then remove the cover. Here's our brake stoplight switch bracket and stoplight switch. We'll go ahead and install the switch onto the bracket. There are 2 adjustable nuts on the threaded portion of the switch. This is for setting the depth of the switch in accordance with the bracket and arm of the brake pedal. We'll just put it on finger tight so we can make any necessary adjustments later. Now we've got our switch on the bracket, we'll go ahead and install the wiring. The green wire, which will indicate the cold side of our brake switch. We can strip it back for a spade connector. This green wire is ultimately going to get connected to the radio controller spade terminal. We've got the red power wire and prep it for a spade connector. Now, because this switch is a simple open or closed circuit, it doesn't matter which connector we put the 2 wires on. Let's go ahead and install them now. Next, we'll go ahead and mount the bracket to the vehicle. We'll use the 5/16ths bolt, split lock washer and nut to secure it. We'll locate the brake pedal support arm that has a pre-drilled hole in it. It will be the highest pre-drilled hole that you can access that's right next to the brake pedal arm. Once we have the brake switch installed, we can now go ahead and mount our transmitter. We're going to mount it here on the driver's side kick panel. Make sure you check your clearance by operating the brake pedal. Once you have it mounted and secured we'll go ahead and take the pigtail that comes from our box and plug it into the pigtail that we ran from the breakaway switch. Then, go ahead and use a zip tie to secure it up underneath the dash. Then we'll follow it up the firewall, white going to ground, red going to power. To hide our wires a little bit, we're going to add wire loom. This will bundle our wires together and help hide them a little bit. Next, I'm going to take the green wire, which is our brake signal switch from our stoplight kit, route it over and run it into the wire loom also. Then we'll plug it into the spade terminal at the bottom of the receiver. Next, to help hold my wire loom in place, we're just going to put a little electrical tape around both ends. We'll then use a zip tie to secure the wire loom. Next, I'm going to take the white wire that came from the transmitter. Once I figure my length, I'll go ahead and cut it off, strip it back and add the ring terminal. Run it over to the body or steel bracket here for our ground. Using a self-tapping screw, we can go ahead and secure the ring terminal. We're going to use the Deka 10 Gauge Primary Wire, part number 10-1-1, strip it back, and use a butt connector to secure the 2 power wires from our transmitter and brake switch. Now, with this connection made, I'm going to go ahead and wrap it up with some black electrical tape. Next, we'll take the power wire and feed it through the center console over to the passenger's side. We'll take the power wire and we're going to tuck it underneath the console trim as we feed it back towards the vehicle battery, which mounted underneath the passenger front seat. Once we've run the wire as far as we can up the console, we'll move the seat forward where we can remove the battery cover, feed underneath the carpeting, and then into the battery box. Once we figure out our length, we'll go ahead and cut it off, strip it back, and add a ring terminal. We can then remove the nut on the positive battery post, install the ring terminal and its positive battery cable and then resecure the nut. Once it's secured, we can go ahead and re-install the battery cover. We'll re-install the under dash panel First, we'll take the brake box and set it in position on the floorboard and then put the clamp around the brake pedal. We'll put the safety bracket and clip in place to hold it. That will lock the arm from the brake box to the brake pedal. Next, we'll adjust the handle, which also doubles as where the seat will help hold the brake box in position. The knob on the back will allow for our height adjustment. I'll loosen the knob, raise it up, and then resecure it. Now we'll move the seat forward against it holding our box in place. There are 2 wires that come with the Even Brake box. One will go into the top of the transmitter, so I'm going to route it behind the brake box. Once in place, you can release parking brake pedal. Next, we can go ahead and go through test mode of the Even Brake box and we'll take the power cord from the box and plug it into a previously installed power port that was run directly to the battery. As you can see, the light will come on the cord when it has power at the outlet. Once we've plugged the box in, the compressor will kick on to build up the air pressure. Next to the green test button, our light will flash red and green and then we'll press the test button. After we press the test button, it will go through the cycle of pressing the brake pedal 3 times. While we're doing that, we can also watch the monitor as it will be plugged into the to vehicle. Now, with our brake box test done, we're ready to hit the road. That does it for the install of the Roadmaster Even Brake Portable Braking System, part number RM-9400, on our 2013 Jeep Grand Cherokee. .
