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.

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.

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.

  • Does the Demco Stan-IN-Play Supplemental Braking System Provide Power to the Towed Vehicle?
    The Demco # DM86VR Stay-IN-Play Supplemental braking system gets its power from the towed vehicles battery to run all of its systems. However, I think you might be asking about the tow bar wiring harness such as the Roadmaster # RM-152-98146-7 that provides the lighting systems (not brakes) for your towed vehicle. A tow bar wiring kit is sold separately from the supplemental braking system. If you need recommendations for other flat-tow parts just let me know.

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

  • Difference Between RM-152-98146-7 and RM-154 Wiring Harnesses for Flat Towing 2020 Jeep Gladiator
    The difference between the # RM-154 and the # RM-152-98146-7 is the trailer connector and the umbilical.
