How to Install the Demco SBS Stay-IN-Play DUO Supplemental Braking System on a 2009 Infiniti G37


Clayton: Hey guys, how's it going Clayton here at etrailer.com. Today I have a 2009 Infiniti g37. We'll be taking a look at, and I'll show you how to install the Demco Stay-IN-Play duo supplemental braking system. This is one of the major six components while we're flat towing. So we have our base plate, our tow bar, our wiring, our braking system, our safety chains and our brake lite relay. So braking system is required on any vehicle being flat-towed.

What our braking system does is take away some of the pressure from the car that if we didn't have the braking system the car would add to the RV, and we don't want to be replacing brake components on our RV, so using both vehicles really helps them on the road. This is a proportional braking system. What that means is, is whatever pressure we give in the RV, the car will get the exact same.Say we're pulling up to a stoplight, and we have to suddenly stop. Our vehicle will stop right with our RV. Keep in mind, this is a more permanent install.

So our system works off an inertia switch. That inertia switch sends a signal to our main unit, which pulls air from our brake booster, pushes that air to our actuator mounted on our brake pedal and that actuator in turn pushes our brakes. So here's our G-Force controller and this makes it very easy when we are getting ready to flat tow our vehicle, we simply just flip our switch and we're good to go, and then there's an adjustment knob for different brake pressure in our vehicle. So the only part visible on our braking system outside of our vehicle is our breakaway switch. What our breakaway switch does is if our vehicle comes disconnected from our RV, it'll apply our brakes stopping our vehicle.

That way we don't have to worry about our car going off the highway.In terms of installation. It is kind of time-consuming, it's not that difficult, but you definitely want to take your time. And speaking of installation, I'll show you how to get it installed now. So to start installation, we mounted our operating unit right here. This is the best place on this vehicle because it's a small car.

I suggest doing this with the fascia off whenever you do your base plate. Our operating unit is going to have four wires. We're going to have red, black, and blue and brown. Our red and black wires are going to go this way. Our blue and brown wires are going to come this way. We have our breakaway switch here. We tied in our black wire from our switch to our blue wire on our unit. We use the heat shrink butt connector.We took our orange wire from our breakaway switch and our brown wire from our operating unit, tied those together, ran them up behind our headlight and under this molding here. As you can see, I pulled it out. We added a heat shrink butt connector, we tied those together, ran it under this paneling and connected it to our fuse. So our red and our black wire we ran this way. Our black wire is going to come up behind our headlight through this molding here and out up here. This wire has to be routed into the vehicle. We'll show you that in a later step. Our red wire, we're going to follow our four-pole wiring all the way back to our G-Force controller and make our connection. Mounting our G-Force controller was difficult just due to the size of the car. There wasn't really a good spot inside of our cabin, so we decided to mount it back here.We mounted our controller right here, ran our wiring down underneath this panel and behind this screw so you don't have to worry about the wire moving around. And there's a grommet located right here, it's kind of hard to see, but we push our wire into there, and it dropped out the bottom. It'll be very easy to connect it to our four-pole wiring there. And then you want to make sure to keep in mind when you mount your G-Force controller that our on and off switch is facing the rear of the vehicle, our Demco lettering is facing the passenger side and then our box is level.So as you can see, all of our wires are ran right here. I connected our G-Force controller to our factory four-pole, that's what all these are. So our white wire to our G-Force and our white wire from our four-pole are right here. We tied those together, put our four-pole back into the connection and are in a separate ground. Everything else, so our green and our yellow, we're going to have two come into this side and one coming from our factory fourfold. As you can see our red wire here, I had to run jumper wire just as an extension from our G-Force controller to our breakaway switch. And these are all heat shrink butt connectors. I'm going to come back and heat those down now.We do need to add one more wire. Our vehicle requires a brake light relay, so we're going to add an extension to our brown wire, run that up with our black wire up to firewall and through a factory grommet. So now when we need to mount our indicator light, we stick it on the back of the mirror. There's a sensor right here, we want to make sure that we're not interfering with the sensor. So we mount it here, run our wiring up and tucked it into our headliner with a pry tool. We just pushed it back in there. We ran it across the top here, down our pillar, all the way down to the side where that panel pops off for the opening, underneath our dash and down to our other wires for our breaking relay. We want to come under our driver's side, down behind our pedals.You need to locate your brake light switch. It's kind of hard to see, but it's right up here. We're looking for our white wire and our blue wire. Our white wire is going to be our hot side and our blue wire's going to be our cold side. When we are connecting our relay, we want to use the blue wire since our vehicle has a push button start. We will not be using the green wire. So before we cut any wires, we want to make sure we find a fuse panel. On our vehicle the fuse panel's located in our kick panel by our left foot. There'll be a little trap door and it'll have a nice diagram here.We'll use our fuse puller as a guide to find our fuse. So that would be located here. And then we'll be on the left side of that, and our fuse is the seventh fuse down and it's a 10 amp fuse. So we'll countdown one, two, three, four, five, six, seven. And then if you want to verify that you can look on the other side, we should have a 15 amp fuse next to it as we do, so we can go ahead and use our fuse puller and needle-nose pliers and pull the fuse out. So now we're going to go ahead and cut our white wire. On the side, closest to our plug we're going to add our blue wire and our red wire from our indicator light. On the long side or the side farthest from our plug, we're going to add our black wire.You want to make sure to leave enough when you cut that there's room to strip the wire back on both sides as this as a tight space. So to make this a little bit easier, I'm going to go ahead and cut off our green wire. We don't use this because our vehicle is a push button start. If you do have a regular key start, you'll be using this wire and not the blue wire. So we can go ahead and trim this back and toss it off to the side. With our connections made to our brake light switch. We can now connect our red wire to our brown wire that runs to our taillights.With this connected now, we can connect our black wire that we ran to the black wire on our indicator light. So we can now take our indicator light wire, put it into our butt connector. This might be tough just because all of our wires are running all over the place. So we'll take that with our crimpers and crimp that down. So now we need to go ahead and ground our ground wire. I'm going to go right here behind our carpet right to the firewall. Now I am going to add an extension just to be a little safe so we are not pulling our wires too tight. So we'll just take this, bend it over, put in our butt connector, crimp it down. Then what we're going to do is tidy up all of our wiring.Instead of mounting our ground behind the carpet there, I'm going to peel back this carpeting here, cut out a little notch and run our ground right here. Now we can go ahead and cut a notch in this and run our ground. I'm going to come back and run our ground wire right back here with a self-tapper. Now with all of our wires stuck up underneath our dash, we can add in our relay switch and install our fuse back into the fuse panel. To mount our actuator we want to find a good spot on the back of our brake pedal to where our pedal can travel how it's supposed to like that. But we also want to make sure that where we mount it, it's not going to interfere with our feet. And since this vehicle is rather small and with it being a manual, it's kind of tough to mount our actuator. We chose right here because we can still get most of our travel, it still applies the brakes and we have enough clearance for our clutch.So I went ahead and tightened down our bracket. You want to make sure that this is tight, that way that actuator doesn't move around when the brakes are being applied. And now with our actuator tightened down, we're ready to connect our airline tube. We want to make sure to connect it at our main unit first, so we'll connect it here, and we ran it up behind our headlight through here, underneath this molding and down to our access hole on our firewall. So now when we are installing our airline tube, we want to make sure that there's no kinks, that it's not touching anything that moves or that it's going to get in the way of our pedals. So I think I'm going to cut it right about here, and I come into our solenoid like this. So with our wire cut, we can go ahead and push it in to our actuator.I'm going to give that a little tug and make sure that's not going to move. And our wires. or our airline tube up here is out of the way of anything that moves. Now, I'm going to zip tie it right here to this factory wiring just so that it stays out of the way of our clutch spring. Now with our actuator completely hooked up we need to run our vacuum line. Our vacuum line is going to plug in to the bottom of our operating unit. So we put our vacuum line on here. We ran our vacuum line underneath our bumper beam, around behind our headlight up the same molding and came out up here. What you're going to want to look for is your vacuum line coming from your brake booster, and this line goes right to your engine.So what you need to do is cut a hole in your factory line at our T fitting. You'll take this side, push it onto here. A little bit farther down you'll cut another gap and you'll put in our check valve. It's important to make sure the black side is facing towards the engine. And the white side is facing towards our T connection. Then we'll take our line from our brake booster, put it on this side and we'll take our new line and put it on this side.Now we're going to want to grab an extra set of hands, hold our fascia up into place and check where we're going to need to trim it. So all of our components fall in this mesh material here, so we'll just kind of eyeball it and figure out where it's going to fall and then we'll come in and trim it out. So we'll take our wired end, put it through our hole in our fascia, drop it through, take our plug, push it through our hole. And then you want to make sure that the brackets on our base plate match up. In this case they do, so we know we're good. Now we can go ahead and add our hardware into our bracket. With this secured we can make our connection.So I've gone ahead and marked our wires here. We want to make sure they meet there's going to be just a little bit extra. We can always secure that with a zip tie. So with this march, I'm going to go ahead and cut our wires, and then I'll grab some cable cutters and we can cut our six pole wire. We want to line up our cutting edges with this, then we can go ahead and give it a cut. So after we make our cut, we're going to go ahead and trim back our shielding on our wires. It's going to be kind of tough because these covers are thick, and you want to make sure not to cut into our wires. With our wires exposed we can go ahead and cap our red and blue wires. We are not using those. So we'll go ahead and strip them back and then add a butt connector, and that should cap our wires. You want repeat that same process for our blue wire.Now we'll want to make our connections from our four pole wiring to our six pole plug. It'll be green to green, yellow to yellow, brown to brown and white to white. You want to cut back and separate our wires. You want to be careful not to cut the wire. Then we can pull those back. Now we can go ahead and strip back our wires, add a heat shrink butt connector, and then we'll crimp it down. We'll come in, strip our green wire on this side. We can add our green wire from our four fold side, crimp it down and give a little tug just to make sure it's not going to move. Now we want to repeat that process for the rest of our wires.Now we can go ahead and heat shrink our butt connectors. You want to be careful when you're doing this. You want to make sure not to melt anything under your fascia. So after you heat shrunk your connections, you can add your wire loom and you're good to go. So once we have everything hooked up, we can now put our fuse holder to our battery. We do want to check and make sure that our fuse is not in our fuse holder, and it's not. So we're going to go ahead and add our connection right here to this bolt. We'll take this off. We can then slide our fuse holder over the top here, add our nut and tighten that back down. With that tightened down we can now grab our fuse, add our fuse to our fuse holder, then we can go ahead and test everything out.You can go ahead and turn it on. You can actually test it out without it being hooked up to your RV. All you have to do is flip your G-Force controller and then you can pull your breakaway switch and then you'll hear your actuator turn on. And then we can check and make sure our indicator lights working so we'll fire our breakaway switch and replace it. You should see that light turn on. Now we'll need to check and see if our actuator's working. You'll need a second set of eyes to check this. We can go ahead and pull our breakaway switch, and you'll see our actuator push down. We're going to place our switch, pull it one more time and we know we're good to go. That's going to do it for a look at and installation of the Demco Stay-IN-Play duo our 2009 Infinity g37..
