A supplemental braking system is a must when towing a car or truck behind your RV. Without it, the weight of the towed car can create a safety hazard, strain your RV's brakes, or affect your RV's warranty. Most states require a supplemental braking system.

Automatic, Proportional Braking

There are many supplemental braking systems available to RV owners who choose to tow a car. Stay-IN-Play DUO combines the best features into a single system that is both automatic and fully proportional. This system relies not only on your towed car's momentum to activate, but also on your RV's brake light signal. As a result, the DUO will automatically activate any time you engage your RV's brakes, so long as there is enough deceleration for the system to detect. And when it does activate, your towed car's brakes will engage with an intensity that matches the slowing or stopping action of your RV.

An inertia-sensing mercury switch inside the DUO's controller is what makes this system proportional. This switch reads and interprets changes in forward momentum that occur when your towing setup decelerates. As your RV and car slow down, this switch sends a signal to activate your towed vehicle's brake pedal with an intensity that matches the deceleration of your RV. The result is even braking across your towing setup. Whether you lightly tap the brakes in your RV or apply them hard in a panic situation, your towed car's brakes will be applied proportionately.

Dual Activation Signals

G Force Controller

The G-Force controller is responsible for sending the signal that activates the brakes in your towed car. When the coach brake lights come on, the tow bar wiring sends a signal to this controller. This signal powers the internal, inertia-sensing mercury switch, enabling it to detect deceleration. If a change in forward momentum is detected, the G-Force controller initiates the braking process by sending an activation signal to the system's operating unit.

If the mercury switch is powered but there is no change in momentum, the system will not activate the towed car's brakes. Likewise, if a decrease in forward momentum occurs but there is no brake light signal from the RV, the inertia sensor will not be able to register the deceleration, and the system will not activate the towed car's brakes.

Because the DUO will not work without your RV brakes being applied, there is no false braking. When you downshift in your RV without applying the brakes, the DUO will not mistakenly depress your towed car's brake pedal because that first activation signal is not there. And because there is no time delay, this proportional system delivers instant braking in an emergency.

Note: The G-Force controller mounts in the towed car and must be pointed it in the direction of travel - with the toggle switch facing the rear of your vehicle - for the internal sensor to function properly.

Sensitivity Adjustment

You can adjust the sensitivity of the inertia-sensing mercury switch with a knob on the front of the G-Force controller. Adjusting the sensitivity lets you decide how intense the change in momentum must be for the sensor to respond. Adjust it to fit your personal preference so that you can get a customized braking experience. Set the sensitivity low and the DUO will only respond when you forcibly step on your RV's brake pedal. Set the sensitivity high and it will respond when you merely tap your RV's brakes.

To fine-tune the sensitivity, first move the knob all the way to its most sensitive setting. From there, you can apply the coach brakes and gradually move the knob until you get the setting right where you want it. You only need to set the sensitivity upon initial setup.

Permanent Installation with Concealed Components

Operating Unit

The operating unit receives the signal from the G-Force controller to activate. It then delivers air through a hose to the actuating cylinder, which depresses the towed car's brake pedal with a pressure that ensures your car will brake in proportion to the deceleration of your RV.

DUO Under Hood

Once you install the Stay-IN-Play DUO's operating unit under the hood of your towed vehicle, it stays concealed. Not only will it be installed and ready for the next time you want to tow your car, but it will also be out of the way so that you won't notice it when you drive your car normally. In addition, there is no need to constantly set up or remove this system. As a result, you don't need to worry about where to store the components when you're not towing.

Actuating Cylinder

Small Cylinder

The actuating cylinder depresses your towed car's brake pedal upon receiving air from the operating unit. This small cylinder stays mounted on the arm of your towed car's brake pedal at all times and will not interfere with braking while driving.

Actuator on Pedal

Mount this cylinder so that it is perpendicular to the firewall when you depress the brake pedal. A clamp anchors the actuator to the firewall.

To connect the actuating cylinder to the operating unit, you will need to run the included air hose through your towed car's firewall. You can usually create the necessary, small opening without drilling. In most instances, you can cut a slit in the hood release cable grommet. Simply cut the end of the air line at an angle to poke it through the slit.

Vacuum Pressure Creates Smooth Braking

Normally, when you activate the brakes in your vehicle, a vacuum multiplies the pressure you apply to your brake pedal, creating the force necessary to stop the full weight of the moving car. On most cars and trucks, this vacuum-assist function does not work when the engine is off. As a result, many supplemental braking systems on the market have to use an excessive amount of pressure to effectively depress the towed car's brake pedal.

The Stay-IN-Play DUO's operating unit ties into your car's vacuum line and uses a built-in vacuum pump to activate the vacuum-assist function of your car's brakes when it's being towed. As a result, the actuating cylinder of the Stay-IN-Play DUO does not need to apply extreme force to the brake pedal to achieve proper braking. The Stay-IN-Play DUO will replenish your towed car's vacuum after each braking event so that you will get smooth, even braking every time.

Built-In Safety Features

Most supplemental braking systems have monitors that tell you when the braking system is activated, regardless of whether or not the towed car's brake pedal is actually being depressed. This means that you might receive an alert telling you that your car is braking when it really isn't. But with the Stay-IN-Play DUO, you get Demco's wireless Coachlink monitoring system. This system ties into the brake light switch on your towed car so that you'll be notified only when your towed car's brake pedal is being engaged. No false notifications.

Demco Coachlink installed

The Coachlink monitor mounts in your RV, plugging easily into your 12V accessory socket for power. The built-in LEDs will illuminate to inform you when your towed car is braking. And an audible alert - which can be easily turned off, if you'd prefer - serves as a backup notification. To receive these notifications, just install the transmitter in your towed car. No additional wiring connections are needed between your car and RV as all communication happens wirelessly.

The breakaway system ensures that your car will come safely to a stop if it accidentally detaches from the RV while you are towing. A switch mounts to the front of the towed vehicle. This switch - which is wired into the operating unit - includes a pin that connects to your RV's hitch receiver with a breakaway cable. If the car separates, the cable pulls the pin from the switch, causing a signal to be sent to the operating unit.

These installation photos are for the Demco Duo Play braking system install on a 2018 Ford Fusion Platinum Energy with push button start.

I works perfect every trip. I do a hard braking test at the beginning of every trip. The wireless monitor in the motorhome immediately reports the functionality of the braking system. I am very satisfied with this product. I installed everything myself.
Jeffrey - 11/19/2022


Great braking system. Installation directions were good and clear, but there are a lot of steps. It is easy to adjust properly once installed and has worked flawlessly for 2500 miles towing my 2015 Subaru Forester.


This is a really nice braking system. It works EXACTLY as described. Engine breaking does not trigger breaking (because it's tied into the break light circuit). And breaking truly is proportional. Light braking and it does not engage activate braking. The remote wireless coach receiver shows you how hard the car is breaking, and IS proportional to the breaking in the Coach. When the car is breaking the wireless receiver shows you, at three levels (the number of lights lit from one light to three) how hard the towed is braking. i HIGHLY recommend the wireless unit for breaking notification.

Instructions were very clear. I studied my 2004 Pontiac Vibe (same as Toyota Matrix), and watched a bunch of online videos on installing this product. This is a particularly good car for a toad, because it is so light. (2700 lbs curb weight -- and it rolls really freely).

Installation was particularly painful under the dash where (as a tall person) I had to contort myself into all kinds of uncomfortable shapes with various padding) to reach up under the dash panel . There is just no easy way I could find to remove the lower dash panel without taking about whole dash board. So just figuring out the cold side of the break switch was very difficult. It was impossible to get a probe on the break light switch plug. I ended up clipping a wire junction connector on to the (green wire coming of the brake switch after unplugging the wire harness) and then probing that after plugging it back in. I guessed right, It's the green wire that is the cold side of the switch. For someone who reads this you don't have to guess. I've done it for you

On this car I was concerned about going through the firewall and puncturing the break booster when mounting the cable terminal for the actuating cylinder. In the end, where I needed to go through the firewall was nowhere near the booster. It also turned out trying to use the self taping screws was just too hard. I wanted to use the reinforcing plate, but ended up loosing it under the carpeting. Finally I decided to just drill a 1/4" hole through the firewall (just northwest of a little dimple in the firewall), and bolt the cable cable terminal to the fire wall with a 1/4x20 combo head machine screw, and a fender washer, lock washer, and nut on the engine side of the firewall. I put silicone on the washers and nut, to prevent corrosion. I had just enough room under the car to get a wrench onto it. It would have been nice to have a car lift in my garage, but I did this work by blocking the car up on jack stands. My son held the bolt on the inside of the car. while I tightened the nut on the engine side of the firewall.

Another problem was: where to mount the operating unit in the engine compartment? I struggled with this until I found an online video of an installation on a Honda, where the tech mounted the operating unit to the engine cover. This worked out well, and made for easy routing of the vacuum lines both to the vacuum line between the engine and the brake booster, and through the firewall grommet to the actuating cylinder.

I mounted the wireless sending unit on the dash at the driver's A pillar, and the control unit on the passenger side, where there was much more room, routing the wires behind the center console over the the drivers side to go through the firewall. Calibration (adjusting the control unit position) worked exactly as describe. I set it and I was done.

In the end, though a painful install process, ESPECIALLY above the foot pedals under the dash, I know I am going to LOVE this system. To setup for towing: just flick the switch on the control unit, and hook up the car. No other special setup is required.


The system is definitely cost effective and works well. More importantly, I had some issues because I tow a very small car. The customer service from Demco was very good. They walked the installers through how to deal with the challenges.

I now have a DemconStay-N-Play system on the Jeep Wrangler I replaced the Fiat 500 with as my tow vehicle. My experience has been much the same and the braking assistance.difference is now more pronounced. My motor home stops as though there is now tow vehicle and I believe even decreases total stopping distance of both vehicles. Tiffin Allegro OPen Road 32 SA w ford V-10, 24,00 lb chassis.

This system was fairly easy to install. However, the installation took some time but if you followed the directions and review the video it should not be a problem to self-install. The system does seem to be a bit finicky regarding the braking adjustments. The towed vehicle is supposed to apply the brakes at 20MPH or above but it seems that the aux brake engages at lower speeds. Additionally, depending on the slope sometime the system will appear to engage when the left or right blinker is on. No matter how I adjusted the Inertia sensor I could not find what I though should be the sweet spot. Overall, I am happy we had the aux brake when traversing some of the mountain passes out west.

You mentioned that the system appears to engage when the left or right blinker is on. We have reached to Demco before about this matter and they stated that the pulsing that you have been experiencing when your turn signal is activated is normal. It is typically caused by the sensitivity being cranked up too high and near the max setting. I recommend continuing to adjust the sensitivity of the inertia-sensing mercury switch with a knob on the front of the G-Force controller until it stops engaging when the blinkers are on. To fine-tune the sensitivity, first move the knob all the way to its most sensitive setting. From there, you can apply the coach brakes and gradually move the knob until you get the setting right where you want it. You only need to set the sensitivity upon initial setup. If this does not solve your issue, then please reply back and we can keep troubleshooting.

System took a little patience finding locations for the operating unit and routing the wires from the controller. Performance for breaking is outstanding! No faults application of brake and very smooth stopping under ask conditions.


Great product and thanks to for the excellent videos detailing how to install the Demco Stay-In-Play Duo braking system. As a result of watching all of the available videos, I learned that there where a couple of different ways to install the system in our Jeep Wranglers. The first installation I did was in our 2019 Wrangler and that was super easy following the one video on your website. The second installation of the system was not as easy because our 2021 Wrangler has a manual transmission and required having to drill a hole in the firewall/floor board to run the wiring and vacuum tube from the passenger compartment to the engine area. If ever has an installation on a Jeep Wrangler with a manual transmission to perform, hopefully they will video tape that installation to guide customers with Jeeps with manual transmissions. I think's idea of mounting the control box on the fuse box is by far the cleanest and easiest way to install the Demco braking system.
I also followed's videos for installing the brake light system and the base plate on both our Wranglers and could not be happier with them. Thanks etrailer for all you offer.


Love the Demco staynplay been using for a few months now and operating this unit couldn’t be simpler. I installed this myself and installation was quick and simple.


etrailer shipped quickly and followed up to make sure I received the shipment and also later to make sure I was satisfied. This is a great company which deals in quality products.

2018 Jeep Wrangler

Works great. It takes some time to install but worth it for the ease of use after. I installed the same system on my 2018 wrangler without the coach link monitor, used it over 4 years and 18,000 miles without a problem. I like the addition of the coach link monitor as the light is right in front of you.

Hyundai Tucson

Everything was delivered as scheduled. eT, recommended Professional Trailer in Tucson. They put 3 guys on it and the Install was 8 full hours. Test of all components coming up this week. The videos are great, even if I didn’t do the install it taught we a lot of what these guys had to do.


Had trouble with a brake fault and power brakes not working momentarily after installation. First Ford dealer wouldn't work on it because of the modification to the brakes. Second dealer was great and found a torn grommet where the Vacuum line connects to the brake booster. Replaced the grommet and redid the added connectors and tees in the Vacuum line to take the stress off the grommet. Has worked fine ever since. Happy with the braking system and would recommend it. Just be careful with the installation on a new ford Ranger. The grommet can't take much stress.


The detailed product installation videos that has on their website are a big help, and a good reason to buy from them over some other company


Class A towing a Jeep. We have been full time for a year now. It has performed great. We have not had any mechanical issues. We do have minor rust spots on the base plate.

Chevrolet Equinox

Between Etrailer videos and the instructions, the installation went very well and the system operates great on my Chevy Equinox. Just finsihed a 3000 mile trip with no issues.


Outstanding customer service! Excellent instructional videos! I could not be happier. As an Rv technician I recommend etrailer to anyone looking for parts or diy assistance.

Ford Explorer

The system is great. I'm installing it on a ford explorer. I had a question about the instructions, and I called customer service. To my surprise, the phone ring once, and I got to talk to the service personnel in less than 2 minutes. I received an answer and a great explanation. Thank you for your excellent service.

The system is working great. No issues.
Jose R - 05/31/2022


This system is time consuming to install but with the help of the etrailer videos the install went well. I really love the system. I have towed my Jeep with my RV a few times down some really steep grades and the system works awesome. The beauty of the system is when you are done towing, you disconnect the tow bars and safety cables, unplug the breakaway cable and brake/turn signal cable, switch off the control unit and your done! Preparing for the tow is just the reverse. I did consider many other types of systems and models, but I'm really happy with the Demco Stay-in-Play Duo. The Wireless Coachlink monitor is also awesome.`


Overall, the system works well. I suffered a controller failure right after the first trip I took towing the CRV, but the prompt replacement has been working ever since then. I did the install myself, mainly because I have mechanical experience, AND I'm pretty picky about who touches my vehicles. I have a 2014 Honda CRV, and I fabricated a mounting bracket for the pump module for installation right between the radiator and intake manifold. I probably have over 10,000 miles driven since the install, and have seen no issues yet with my install (controller module failure notwithstanding). The 4 stars reflect this rather early module failure.


Etrailer videos made this a pretty simple install. So far so good.

by: 04/08/2021

Works great. Self installed on 2018 Ford F150 without much difficulty. I recommend watching etrailer install video. Mine has wireless duo monitor. Extra care needs to be used when splicing into tiny brake light switch wire. If bad connection is made truck will not shift out of park.


Settings for proportional braking on this unit is critical. If the compressor runs too long (by way of the setting being too sensitive) , it draws too many amps and blows the unit fuse. In turn, the system quits working. This makes me wonder what would actually happen on a break away.

For me, it was marginal if I needed the system given the light weight of my small tow car - so even with the adjustment on when the system breaking, it works ok.

I contacted the manufacturer about the issue with blowing fuses. He said, the most common reason for blown fuses with this controller is when it is not set correctly. The system is designed to use the brake signal from the coach and the forward inertia. The pump should only turn on when these signals are present. I would go through step 12 in the instructions again just to be sure that everything is working properly.

Jeep Wrangler

etrailer is special. They have all the information you need to have about the products you are looking for. I am a first time RV owner and was looking for a way to flat tow my Jeep Wrangler. etrailer made it so easy for me to understand what I should be doing and the best and safest way to accomplish it. But that was not all. I was having issues trying to find shipping options as I had a time crunch. I phoned them, customer service was awesome. They helped me place the order and get it to my home within my time requirements. I honestly recommend them and can only wish that other companies could treat customers the way they do here. Awesome! The videos on the product pages are the best!


The system does what it is supposed to do. Once installed it is very simple to use. Turn on the switch, and the in cab monitors confirms its operation.


Great company to work with. The braking system was fairly easy to install and works great.

    I don't believe that a Coachmen Pursuit 32WC has air brakes, so the Air Force One would be out of the question.

It also is used to adjust the braking sensitivity to ensure that the brakes are not activating to hard or soft. You want the switch in the off position when you are using your 2003 Jeep Grand Cherokee for everyday driving. It will be switched to on when you are flat towing your Jeep.

  • Vacuum Line Fitting Needed To Install The Demco Stay-In-Play In A 2020 Ford F-150
    Demco does list in the installation manual for the Demco Stay-IN-Play DUO Supplemental Braking System # DM86VR that newer Ford's may need an additional check valve due to Ford using two vacuum lines, but I called my contact at Demco and confirmed that you would only need just the Demco Vacuum Connection Tee Fitting # DM6257 that you referenced. The line is going to be a hard plastic and the tee fitting will slide right over it for an easy installation. Page 16 of the manual will walk...

  • Troubleshooting the Auto-Stop-Start of the Demco Stay-IN-Play DUO Supplemental Braking System
    Sorry to read you are having an issue with the installation of your Demco Stay-IN-Play DUO Supplemental Braking System w/ Wireless Coachlink Monitor, # DM86VR. I contacted the Demco Tech Reps and they have a suggestion, replace the rubber grommet in the vacuum booster. They stated that if you used the Demco Vacuum Connection Tee Fitting # DM6257, which you did, then about the only thing that could potentially be causing a vacuum leak would be the rubber grommet in the vehicles brake booster....

  • Flat Towing With a 2021 Jayco Precept Motorhome
    Since you'll be flat towing a vehicle instead of just towing a trailer with your 2021 Jayco Precept Motorhome you will need a supplemental braking system and not a standard trailer brake controller. Trailer brake controllers like the Tekonsha P3 # 90195 are designed to activate the brakes on a trailer directly while supplemental braking systems will push down on the brake pedal of your vehicle to activate the brakes. I recommend the Demco Stay-IN-Play DUO Supplemental Braking System w/...

  • Is It Necessary To Keep The Breakaway Pin In The Demco SBS When Not Being Flat Towed?
    It is recommended to keep the Breakaway Switch Pin # SM99905 in at all times with either the Stay-In-Play # DM86VR or Air Force One # DM26VR. The pin will not only protect the braking system from activating when not needed it also keeps the dirt and debris out of pin hole. If you are worried about something catching on the loop you can purchase a spare Pin # SM99905 and cut the loop off to use when you are driving around.

  • Will Demco Stay-IN-Play DUO w/ Coachlink Monitor Braking System on 2021 Jeep Wrangler Unlimited
    Good questions, and the answer is yes, the Stay-N-Play DUO with the Coachlink will allow you to monitor the brakes on your 2021 Jeep Wrangler Unlimited as it is being flat towed, and you'll also need a brake light switch. As far as the best one, there is a switch from Roadmaster which is designed specifically for your Jeep, so here is exactly what you'll need: - Demco Stay-IN-Play DUO Supplemental Braking System with Wireless Coachlink Monitor # DM86VR - Roadmaster Stop Light Switch Kit...

  • Can Stay-IN-Play DUO Brake Be Installed on 2020 Jeep Gladiator if Motorhome Has Air Brakes
    Yes, you can use the Demco Stay-IN-Play DUO # DM86VR as opposed to the Demco Air Force One # DM26VR for flat towing your 2020 Jeep Gladiator even though your motorhome has air brake lines. We don't usually recommend going this route because of the Jake brake scenario you mentioned but as long as you understand what needs to be done to safely brake then you'll be just fine. Be sure to pick up the Roadmaster Stop Light Switch Kit # RM-751497 so the Stay-IN-Play DUO is able to detect the...

  • Why Isn't Roadmaster InvisiBrake Supplemental Braking System Good For Mountainous Areas
    That's a good question, and the reason the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 is not a very good option if you will be flat towing in mountainous or hilly areas is because it applies the same amount of braking force no matter what. A set amount of braking power is not optimal for mountainous areas with steep inclines and declines because when ascending there will be too much braking power, putting more pressure on your RV and making it more difficult to climb,...

  • Does Demco Stay N Play Require Using Brake Lite Relay Installed in 1993 Jeep YJ
    When you use the Demco Stay In Play part # DM86VR in your 1993 Jeep YJ Wrangler you will need to use the brake lite relay part # RM-88400 to prevent the Demco from overriding the turn signals when it steps on the brake.

  • Does Demcos Stay-IN-Play DUO Include Harness for Taillight Wiring
    When using the Demco # DM86VR Stay-In-Play DUO braking system, you would indeed still need a taillight wiring harness like the Roadmaster # RM-15247 diode kit so the taillights on the towed vehicle work in tandem with those on the motorhome while the vehicle is being flat towed. In order to flat tow your vehicle, you'll also need a tow bar, base plates, safety cables, the taillight wiring harness I touched on above and possibly a high/low adapter plus a few other odds and ends. If you'd...
