Time-Delayed Braking

The Activator IV applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Activator. The controller then sends power out to your trailer brakes to activate them with an intensity set by you, at a rate determined by you. Both the amount of braking power (output) and rate of application (sync) can be adjusted to suit your preference, the road conditions, type of trailer, and size of the load. To determine which levels are best for your application, you must test out your towing setup and choose what feels best.

A time-delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches the set maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, the Activator sends power out in the same way, with the same user-set delay, no matter the braking situation. Although this delay always exists, it can be adjusted by changing the sync setting. The controller will continue to send out power to the trailer brakes as long as your foot is on the brake pedal, even when your truck and trailer have come to a stop.

Built-In Controls on the Activator IV

Built-In Controls on the Activator IV

The diagram above shows the controls and components of the Activator IV electric trailer brake controller.

Power Output Control

The power output control lets you set the maximum amount of power that will be applied to your trailer's brakes. Typically, the power output is only readjusted if you switch from a heavy, loaded trailer to a much lighter, empty trailer - or vice versa. During the initial setup process, use the plus and minus adjustment buttons on the top left of the Activator IV to adjust the output.

Sync Control

The sync setting represents the elapsed time from the point that the brakes are first applied to the point that the set power output reaches its maximum. This setting is responsible for determining the aggressiveness of the braking action.

To adjust the sync, use the plus and minus buttons on the top of the unit. If you want to reach maximum power output faster, press the plus button. To get smoother braking action by supplying power to the trailer brakes more gradually, press the minus button. You can alter the sync setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.

Digital Display

The Activator IV brake controller features an easy-to-read LED window that displays the power settings as you adjust them. The power output is shown as a number, with 0 indicating minimum output and 10 indicating maximum output. The sync setting is shown as a number followed by the letter "o" to differentiate it from the output reading. The least aggressive sync setting is 0o and the most aggressive is 9o.

While braking, the unit displays the power output. To see or adjust the sync setting, step on your brake pedal and press either the plus or minus button at the same time.

The display will also show trouble codes to alert you to any potential problems, such as short circuits or overloads, or if there is an internal problem with the controller.

Slide-Bar Manual Override

The manual slide lever overrides the preset power output and allows the operator to engage the trailer brakes without using the vehicle's brakes. In addition to being a necessary safety feature, this option helps to control trailer sway by slowing the trailer to put it back solidly behind the tow vehicle.

You can also engage the manual override to help you move a sliding 5th-wheel hitch closer to your truck's tailgate for tight maneuvering during slow speed turns. Just apply the manual override to hold the trailer in place while slowly moving the tow vehicle forward.

Quick, Simple Installation

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle or position it in any particular direction. As a result, mounting options are limitless, so long as you can still easily access the manual override.

Installation of the Activator IV requires that you either purchase a custom wiring adapter designed to plug into the controller or that you hardwire the controller directly into your vehicle. To hardwire the controller, you must remove the plug at the end of the integrated wiring harness.

Installation Accessories

A vehicle-specific, dual-mated wiring adapter is available for most newer trucks and SUVs with tow packages. One end of the custom adapter plugs into your vehicle's brake controller port, and the other end plugs into the controller - no hardwiring required.

A universal wiring harness (20127 - sold separately) that plugs into any Draw-Tite brake controller is also available. The 4 leads on the universal harness can then be hardwired into your vehicle. By splicing the universal adapter into your wiring instead of directly connecting the brake controller to your wiring, you gain the ability to unplug and remove the controller from your vehicle should the need arise.

Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Video Transcript for Draw-Tite Brake Controller - Time Delayed Controller - 5504 Review

Today we're going to review part number 5504. This is is Draw-Tite Activator IV Time Delayed Trailer Brake Controller. This is designed for trailers from using one to four axles. This brake controller will activate your trailer brakes with a pre-set intensity. The signal is sent to your trailer brakes when your tow vehicle's brakes are activated. This time delayed brake controller is so-named that because there is a delay between the time that you initially apply the brakes on your tow vehicle and the time that the controller reaches the set maximum power output.

Although this delay will already exist, it can be adjusted by just changing your sync setting, right over here. What I am going to do, just so can go through these, is I have an example of a plug here. I'm going to plug this in, so we have power to it. Now that I got it plugged in, turn the power on and I just want to show you, initially if you do not have your trailer connected, when you try to apply the brakes all you will see is that red dot. That just means the trailer is not connected. I'm going to connect the wire to the trailer.

With that wire connected, you'll see, when we apply the brakes, it'll give you the readings. So, what we're going to do now is we're going to talk about it. The sync setting that I had mentioned, you can change that sync setting. This will let you adjust the aggressiveness in which the brakes are activated. Right here it says sync.

These buttons right up here at the top, the plus and minus button, what you'll do is you can increase your activations speed. It will give you full power output a lot faster, just by pushing the plus. Basically, if I go plus, you can see it raises it 3, 4, 5, 6, 7, 8, 9. Nine is the highest. You go minus, you can see it brings it all the way down to 1, whoop it will go all the way down to 0, I'm sorry.

Zero up to nine, so that will . Now, if you decrease that activation speed . In other words, if you have it 5, let's say, and you put minus and go down to 4 or 3, when you're decreasing that activation speed, this will supply the power more gradually and give you a lot smoother braking. Over here is the gain, the power output control, which is also know as the gain. This part will let you determine the amount of power sent to your trailer and brakes. So, the same way as a plus and a minus. If you set it to a higher, you can see it goes up to 8. It goes up by half, all the way up to 10, 9.5, 9. So, if you go higher output, when tow . You'll use that when you're towing in like a hilly terrain or with a fully loaded trailer. If you go minus or back off the power, you'll do that when you're towing a light weight or an empty trailer, so it's going to control the amount of power sent to your trailer's brakes. The manual control slide lever right here, as you can see, this will override the preset power output and allows the operator to engage your trailer brakes without using your vehicles brakes. This will, if you'll notice, when you push this all the way, goes up to 7.5. Seven and a half you'll notice is what the gain setting was, so the gain is what you'll be . Whenever you push this slide lever, it's only going to go up to the maximum gain that you have set on it. It does have this nice, easy to read LED digital display. This will give you your brake power output, the sync setting. It'll also give you air codes. It'll show diagnostic codes for any overloads or open ground and it is short circuit protected. This is a very quick and easy installation, as I'm mentioned, it's a plug and play installation. What we do recommend . This can be mounted at any angle, at any plane, in any direction. Because it's not like a proportional brake controller, it doesn't rely on any inertia or the accelerometer in here. It doesn't rely on any of that, so it can be mounted in any direction. The mounting bracket, right here, and the hardware is included. As you can see, the bracket would just slide in there. You mount it up to the side and then to your vehicle. We do recommend when you do install this, it's possible to use a plug in vehicle specific brake controller adapter, which we do sell separately. Some vehicles will have this adapter plug that you can buy with the end that'll slide into the brake control. The other end can be either wired to your vehicle or it can have a plug that would match the brake controller port in your vehicle. Again, a few specs on this, the application . This is for trailers with up to 4 axles or 8 brake assemblies. It is designed for use with electric brakes only. The harness length off the controller is about 8" and this does come with a limited lifetime warranty. Again, just to show you, you're going to set the sync. You can go high or you can go minus and if you're going to set the gain, you can go up by half inch increments, all the way up to 10 or all the way down to 0. Then again, we have the gain set at 2, when you go apply your manual override, you'll see that it'll only go up to the maximum gain setting. That should do it for the review on part number 5504, the Draw-Tite Activator IV Time Delayed Trailer Brake Controller designed for one to four axles. .

I am still trying to install your product on my 2018 Chevrolet Silverado. I was under the impression I simply had to mount the bracket, mount the device, plug it in, and adjust it. Unfortunately, it does not plug into anything under my dash. I need to cut and splice some wiring...I need to discern which wires to cut and splice first. 597754

No need to cut or splice anything. Youll need a brake controller wiring harness adapter, which we offer as part # 3016
Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers
. The harness plugs into the junction panel under the dash on the firewall behind the emergency brake pedal, as shown in the video Ive linked for you. One end of the harness plugs into the connector in the junction panel, the other plugs into the connector coming off of the back of the brake controller.

This brake controller was remarkably easy to install and worked well right out of the box. I followed the recommendation of etrailer for my make and model of truck, a 2000 Chevy Suburban, and everything was exactly as depicted in the video. After viewing the video I felt as if I had done it before when I went to install my device. I was surprised that it really was as easy as it had appeared in the video. Great job, etrailer! I will definitely be back! 156382

My son just bought a Popup camper. So we bought a draw-tite class lll frame hitch receiver pn75073, a draw-tite brake controller pn5504, a universal brake control wiring kit pnETBC7, and a custom fit wire harness pn118329 for his truck. It took us a couple of hours to install. The instructions were spot on. He hooked up the camper to his truck, and drove off. Worked as advertised. (hope I get to see him soon!!) 335704

I used the trailer brake for only one trip and it performed just fine. I did have some issues "tweaking" the sensitivity....couldn't quite dial it in so braking was smooth near the stop. Otherwise, good product. 519807

A time-delayed controller like the Activator IV can be a little tricky to adjust for the smoothest braking. Use the gain control to adjust the amount of power delivered to the trailer brakes. Ideally, you want them set right before they would lock up. The synch control determines how quickly the power is delivered to the brakes. Its best to start in the middle of the range, and incrementally adjust it higher then lower until you find the setting that gives you the smoothest braking.

This break controller and harness installs in a 2014 Silverado with factory wires already installed. If you want to install in the dash where the factory break controller should be ,it fits with some modifications. First be careful when cutting the back of dash board. The factory wires are connected to the back of the plastic that you will cut out. The wires are located top right of the panel. Stay away from this area. You will also need to cut out the back bottom to feed the plug from break controller to drivers side fuse panel and run down under the dash board on top of parking break. Remove the black cover next to break pedal and plug in the wire harness. You will need to cut out a piece of plastic on the side of the cover box next to the plug insert, because the harness is not long enough to route thru the top. The break controller will stick out of the dash about 2 inches. This gives access to top control buttons. I mounted it this way because I like it at eye level and not down by my knee. Also did not want to drill holes in my leather appointed dash. 145442

Control works great no problems

Just wanted to throw it out there for reference for any future searches. Note that part # 3024-P (Wiring harness adapter) was also necessary for full plug and play installation. This was for installation on a 2020 RAM 1500 (DT) which did not have a factory tow package or brake controller installed. I reviewed the etrailer installation video on a previous Gen RAM and it said the plugs would be right above the gas pedal. At first, I couldn’t find the OEM harness plugs; There weren't any plugs just hanging out in that area. When I got my package yesterday, I decided to take another looksee. This time I easily found it. Looking from under, I could see the two plugs snuggly taped together with black material, not electrical, tape. Looking up from my under dash position they were slightly to the left and up. If you have huge hands and forearms, it may take some positioning, and skin cuts, to get to. Luckily I don’t, but took a little finesse to get the tape off. Once I got that off, there was plenty of room to work and plug my adapter harness into. The brake controller came with a mounting bracket and sheet screws to mount somewhere. Under our dash, there’s a metal dash screw right about the gas pedal that works perfect to mount the bracket. I put on a zip tie as well to make sure it was extra secure. Zip tied the extra slack of the OEM harness and adapter harness under the dash. Very easy install. Unfortunately, no input yet on how it works. Looking at picking up a car trailer this weekend. 751407

Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like the Quickee Tester, part # ALL640595, you should get output to the controller side of the wire you severed. If the manual slide activates the trailer brake output wire properly,...

  • Troubleshooting Trailer Brake Controller on 2003 GMC 2500HD Sierra 4x4
    When troubleshooting the brake controller on your 2003 GMC 2500HD 4x4, I would first start out by using a circuit tester like part # 40376, to ensure that the red wire coming from the brake controller has power when the brake pedal is pressed. If the red wire does not have power, a problem most likely exists with the wiring harness or somewhere on the truck. If the red wire does have power, then you most likely have a faulty brake controller and it will need to be replaced. In this case...

  • Troubleshooting Draw-Tite Activator IV # 5504 that Displays only Decimal Point
    If all you are getting is a decimal point on your Draw-Tite Activator IV # 5504 when you press the brakes of your tow vehicle that means that the controller is not detecting the trailer's brakes. Typically corrosion on the trailer connector causes this. Try cleaning the brake output post on both the vehicle and trailer connector to see if that fixes the problems. Aside from that you will need to trace the brake output circuit from the trailer connector back to the brake assemblies,...

  • No Trailer Brakes with Brake Pedal on the Draw-Tite Activator IV Part # 5504
    It sounds like you have attached the Draw-Tite Activator IV Trailer Brake Controller part # 5504 to the wrong stop light switch. The red wire on the back of the controller needs to be attached to the cold side of the brake pedal which is the wire that only has power while the brake pedal is depressed. You can find this wire using a circuit tester like part # ALL640595.

  • Wiring a Brake Controller to a 2008 Ford F-150
    On your brake controller the red wire is the stoplight switch circuit of the brake controller and it would wire to the green wire of your harness that is labeled stop lamp. The black wire of the brake controller is the 12 volt power source and would get run to the red wire of your harness that is labeled feed wire. The illumination circuit isn't used. The blue wire is the brake output circuit of the controller and would get run to the blue wire of the harness that is labeled electric...

  • Wiring Adapter to Install a Reese Brakeman Brake Controller in a 2014 Ford F150
    I believe the Reese Brakeman Brake Controller you mention is the same controller as the Activator IV Brake Controller, part # 5504. And the correct harness to install this controller in your 2014 Ford F-150 if it has a factory 7-way would be the Tow Ready Plug-In Wiring Adapter # 22292. If you have a 4-way connection you would need the # 22292 as well as a 7-way part # 37185. Check out the FAQ article I attached that shows how to connect the # 37185 to you factory wiring. I attached...

  • Troubleshooting Poor Brakes on a Triple Axle Trailer with One Wheel Locking Up
    Wire size, brake shoes, hubs or magnets could be the problem here. You will need to inspect the trailer brakes to see what is causing your situation. We have a video (see link) that will help you to determine the problem and I will outline how to check things for you. If the brakes on one or more axles are worn significantly more than on other axles you may need to replace the brakes. In this situation I would replace all of the brake shoes at the same time to ensure even braking (see...

  • Recommended Time-Delayed Brake Controller For Motorcycle Towing Camp Trailer With Electric Brakes
    The Prodigy P3 brake controller, part # 90195 is a great brake controller and one of our best sellers, but for a motorcycle you might be better off using a time delayed brake controller. The brake controller I recommend is the Draw-Tite Activator IV Trailer Brake Controller, part # 5504 because it is smaller than most other controllers at 4-3/16 inches long x 2-3/4 inches wide x 1 inch tall. The advantage of a time-delayed controller is that you can mount these at any angle versus the...

If you click the link I've provided, you can see a run-down that explains how a brake controller is installed. A diagram is also provided. The red wire on the controller is tapped into the cold side wire on the brake stoplight switch located at the top of the brake pedal assembly. The switch can have several wires exiting it.

  • Not Getting Full Voltage at Trailer Brake Magnets After Installing New and Larger Brakes
    Usually on tandem axle trailers the brake magnet wiring is jumped from the front to the rear axle. You can try it other ways to see if that helps. I recommend grounding the brake magnets near the brake assemblies to avoid any voltage drop off. Make sure the ground locations are clean and free of corrosion. You didn't mention the wire gauge being used but for electric trailer brakes we recommend 10 gauge such as # 10-1-1 sold by the foot. You can also check the trailer and vehicle...

  • Brake Controller Wiring Installation in 2012 GMC Terrain
    The vehicle wire that needs to connect to the brake controller's red input signal wire is the one that goes to the cold side (load side) of the brake light switch. This is the wire that goes hot only when you press on the brake pedal but at no other time. A circuit tester like # 40376 will let you test to find this wire. The remaining three wires from the controller connect as follows: the WHITE ground wire connects to battery ground terminal; the BLACK 12V power wire connects to the...

  • Are Settings Maintained on Draw-Tite Brake Controller, # 5504 If Trailer is Disconnected
    The Draw-Tite Act IV Brake Controller, part # 5504, does not need to be reset if the vehicle is shut off or every time you connect a trailer. It does retain the settings. Most brake controllers are designed with that feature. The output control on the brake controller that is adjusted during initial setup, is fine if you are towing the same trailer, with the same load, in the same road conditions. If you change trailers, the load on the trailer, or if the road conditions change you...

  • Should Electric Trailer Brakes Function Grounded to Trailer Frame
    As long as the frame of the trailer is grounded properly to the trailer harness yes, trailer brakes will work just fine grounded to the frame. You can try running a jumper wire from the assemblies to the trailer harness to see if that helps. To test the magnets of electric brake assemblies you would need to check out the help article I attached on the subject.

  • Draw-Tite Activator II Brake Controller Decimal Point Always On Even without Trailer Connected
    On the Draw-Tite Activator II if the decimal point is lit up all the time with no trailer connected it indicates an issue on the red wire. The red wire is an input wire that tells the brake controller when you are stepping on the brake pedal. It could be connected to the wrong brake switch wire or to a different switch such as the cruise control. You will need the brake switch wire that only has power when the brake pedal is pressed. If it has power at any other time, such as when the...
