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

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

The Draw-Tite Activator lV Trailer brake controller appears well built, stout and sturdy. Along with the controller it was supplied with the mounting bracket as well screws and instructions providing for an easy install. Draw-Tite is a trusted supplier for trailer needs who have been around for a long time.

Great product, great name
bryant m - 12/17/2021


I have had brake controllers before but, mine were the ones where you had to cut into the vehicles brake line to install the special tee to get a flow back to the controller. This Draw-Tite is all electronic which is nice. Very easy to install. The hardest part to the install was determining the best location under my dash for it. It is a very simple controller to use pretty straight forward. Have had it a year now and works fine.


Finally got to use this unit with my 24 ft Tavel trailer and it worked great. Installation was a breeze. Also purchased plug and play harness specifically for my vehicle, made life a lot easier. Very happy with the unit.


Great product, great service, fast shipping ! Install was a breeze with direct fit harness. Install complete in 20min!

One race season down and it worked flawlessly
Jacob S - 01/16/2021


easy install took longer to get tools out than to put in definitely plug and play with wiring adapter


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.


All items arrived sooner than expected and well packaged and protected. Brake controller and wire harness were perfect fits and easily installed. Installed controller on driver side kick plate under dash. Easy to reach and use/adjust but doesn’t hang under the dash or get in the way at all. The extended tow mirrors were easy to set up and adjust and fit my truck well in spite of being “universal “ fit. Not sure if the mirrors will provide the benefits I grope for as have not yet had the opportunity to use them while towing.


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.

Control works great no problems
Rick - 08/09/2015


Works as it should. Easy plug and play. Super Fast shipping


Have not used brake controller yet. It is ready to be used.


Arrived sooner than I expected. Watched one helpful installation video (not exactly the same vehicle nor same brake controller but still useful). Took me about an hour and half (with heat breaks) to figure it all out and install. Works great. My only regret is that I waited so long to get to it. Saved over $250 compared to RV repair shop installation.


Replaced an outdated Activator II brake controller in my 1999 Ford F250 with this one. Very easy to install (Combined with the Tekonsha Wiring Adapter), and worked great right out of the box! Would definitely recommend this to anyone with an older truck looking to add or upgrade a break controller. I must also mention the excellent customer service from etrailer. Thanks again!


i cant say enough about etrailer order parts they arrive at my home in few days i have three dealerships close to home that cant even come close on prices i have bought several iteams from etrailer with great saticfaction keep up the good work


It’s very good parts working well I really appreciate it I’ll be shopping with you soon thanks for the note


Purchased the Draw-tite brake controller and wiring adapter. Installation was simple after watching the video. Havent tested it pulling a trailer yet. Thanx again etrailer!!

Works great! Was simple to use,really liked the manual brake feature on steep declines, where I didnt have to use the trucks brakes so much, slowing the trailer down.
Cosgrove - 07/11/2020


Excellent products and service. They have what you need for all towing needs, and also quick shipping!


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.

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.

Update: thanks much guys! I was not aware of the wiring harness control adaptor. I purchased it and the process went swimmingly. Thanks guys!
Barry - 01/16/2020


I have been using my brake controller for 1year now, absolutely no problems, works and performs great! I have them in both of my business trucks. This is a great choice at a great price!

Another year has passed, brake controller is performing just like the day I installed it, perfectly!
Morgan B - 05/27/2021


The quality seems questionable compared to other controllers I have owned, will see how it preforms when I tow the trailer for the first time. I can’t complain about the price, very reasonable!


The draw tite brake controller arrived very quick. I installed it very easy on my 2015. Ram. I called Tekonsa and made sure what plug in wiring adapter need it was the 3024 p. I was told by service tech Tekconsa that they maiddraw tite. Also the guy from etrailer I order from new all the questions, very good at his job. I installed it in about an hour and that was finding the best place. The adapter plug is above the gas peddle. Will from etrailer again. Good Luck you will be satisfied.


Works like a charm, I will purchase from you again. The plug and play adapter worked perfect.


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!!)


A great product, great service, easy install. The trailer brake connection installed in the production of my Honda Ridgeline can be difficult to locate. Tip- Look straight in through the small space between the bottom of the dash and the cover skirt below it. It is in clear view and although a tight space it can be unclipped pulled down to a workable area.


The electric brake controller was exactly what I needed. Installation was simple & easy. I also ordered the plug & go adapter cord so the wiring was quick & easy. I am totally pleased with my choice.


You guys never aware me that I would need an extra connector for the break controller or maybe I missed that in some point, so now I have everything but I’m missing that connector in order for me to connect the controller, I need to order it!??????

The brake controller adapter that plugs into the draw-tite activator and under the dash in your 2001 Ford F-150 is part # 3035-P
Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers - Ford, Lincoln, Mercury
. This brake controller adapter is the only part you will need if the truck came equipped with a factory 7-way. If the truck has a factory 4-flat connector you will need part # 118242
Ford Replacement OEM Tow Package Wiring Harness, 7-Way
to give you a 7-way connection. If your truck did not come equipped with either connector you will need part # ETBC7

and a 4 flat connector to hardwire in a 7-way connection.

  • Where Does Blue Wire of Brake Controller Go
    When wiring up a brake controller like the Draw Tite Activator part # 5504 the blue wire runs to the brake output pin of the 7-way at the rear of the vehicle which will be in the 5:00 pin.

  • Troubleshooting Draw Tite Activator that Shows Intermittent Connection
    The single dot on your Draw Tite Activator # 5504 indicates that the controller has power but is not sensing a trailer connected. If this is happening with a trailer connected and it's intermittent that is almost always related to corrosion built up on the trailer connectors. Take some sandpaper to the pins on the connector in the 5:00 position and the connection should be improved to the point the issue will go away.

  • Troubleshooting Trailer Wiring That Stopped Working on 2005 Chevy Silverado
    I'd check the backside of the connector for the condition of the wiring. Most likely something damaged some wiring if several of the circuits just stopped but one is left working. Another possibility is corrosion on the pins of your 7-way. You can try cleaning them with sandpaper. Or you can also check the trailer wiring fuses underhood to see if you can find any blown fuses.

  • Troubleshooting Blue Wire on Trailer Brake Controller Always Getting 5 Volts
    The blue wire coming from the back of a trailer brake controller like the Draw-Tite Activator # 5504 that you referenced will always have some type of minimal voltage on it, but it should be more of a pulsating power and not constant. This is basically the controller's way of looking to see if a trailer is connected. While 5 volts is a tad higher than what is typically seen, if the voltage you mentioned is pulsing and not constant, then this isn't a problem as long as everything is working...

  • 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.

  • Troubleshooting Brake Controller that Doesn't Show Trailer Connection
    A single red dot on the Draw-Tite Activator IV # 5504 that you referenced means that a trailer is not connected currently.

You'd want to clean the pins on your trailer wiring first which will most likely fix the problem.

  • Why Does Manual Override Lever of Brake Not Go All the Way to Max Voltage and Instead Max Setting
    Ideally you set the max braking pressure for your controller to just right before where the brakes would lock up as that is the best stopping setting you can use. If you go further than that to the point where the brakes lock up you actually won't be stopping as quick and you might lose control of the trailer. That is why it's best to have the max brake pressure setting for your controller as right before lock up and not just max voltage.

    Based on your description of the symptoms it sounds like you may still have a bad brake light fuse or relay. Since the Activator brake controller # 5504 does generate brake output power and activate your truck and trailer lights with the manual override engaged this tends to suggest that there is not any internal fault in the controller. I recommend replacing the relay and re-checking all fuses for the truck light circuits.
