Power Output and Sync Adjustment

Draw-Tite Activator IV Controls and LED Display

Power output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. You want to go as high as you can without the trailer brakes locking up. It adjusts on a scale of 0 to 10.


Once you have the power output set, you can fine-tune your braking by adjusting the sync control. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, decrease the setting. 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.


LED Display

The Activator IV displays the power settings as you adjust them. While braking, the unit will display the power output setting. To see or adjust the sync setting, step on your brake pedal and press either the plus or minus button to increase or decrease the setting.


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.


Installation

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. Your mounting options are limitless, so long as you can still easily access the controller and manual override. And because the included wiring harness is custom fit for your vehicle, you can just plug the controller in. No cutting or splicing needed!


Note: If you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately).


Time-Delayed Braking

What is time-delayed braking

Time-delayed braking means that when you apply the brakes in your vehicle, the controller activates the trailer brakes at a pre-set intensity and rate. Both the amount of braking power (gain) and rate of application (load) can be adjusted to suit your preference, the road conditions, the type of trailer, and the weight of your load. To determine which levels are best for your application, test your towing setup and choose what feels right.

Installing this into my 2005 Tahoe was a breeze. If you just follow the directions and check out etrailers videos you should have no problem. I went from a small popup to a bigger hybrid so I had to get the EBC system. This sure beats taking it to the RV or Dealer store and paying retail plus labor. Thanks etrailer.com

  • Troubleshooting a Draw Tite Activator Brake Controller part # 5504 that Only Displays a Dot
    Sounds like the problem lies somewhere in the brake output circuit. When a trailer is connected to the Draw Tite Activator Brake Controller part # 5504 and all that is displayed is a decimal point it means that the controller is not sensing a trailer being connected. Typically the problem lies in the trailer connectors. Usually there is corrosion on this circuit that prevents the circuit from being completed. Check both the inside and outside of the connector for corrosion or exposed...

  • Troubleshooting ER Code on Draw Tite Activator Brake Controller
    I wish I had better news, but the ER code means that there is an internal problem on the Draw Tite Activator part # 5504 and that it needs to be replaced. For a new brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the...

    Hey Phil, Are you hitting the manual override when you're testing the output of your Draw-Tite Activator IV Trailer Brake Controller # 5504 or are you just hitting the brake pedal? Is the decimal point always on the display or only while you're pressing down on the brake pedal. If you are seeing the decimal point all the time then you have the red wire from the brake controller harness spliced into the wrong wire for the sold side of the brake light switch. LED lights don't really have...

  • Factory Brake Controller Port Location on 2017 Nissan Titan
    To install the Draw-Tite Activator Trailer Brake Controller # 5504 that you referenced to your 2017 Nissan Titan, all you will need is the Plug-In Wiring Adapter # 3050-P if the truck is equipped with the factory 7-Way. One end of the harness will plug into the brake controller itself, while the other end will connect directly to the factory port on your Nissan Titan. The factory brake controller port should be located behind the dash, on the left hand side by the emergency brake pedal....

  • Why is my Brake Controller Reading Overload and How Can I Find Where the Problem is?
    If your controller, item # 5504, is reading overload without the trailer connected then that means there is a short in the blue trailer feed wire on the vehicle. If the controller is reading overload only when the trailer is connected then there is a short or overload in the trailer wiring or breaks. Use a circuit tester, item # 3808 if you need one, to test the wiring to find out where the short is. If it is on the trailer end and you cannot find a wiring problem then the problem may...

  • Where is the Brake Switch Wire on a 2014 GMC Savana Van to Install a Brake Controller
    I can tell you were to access the correct brake switch wire to install a brake controller on your 2014 GMC Savana Van. You will need to access the wire behind the BCM (body control module) located behind the dash on the passenger's side of the vehicle. There should be a brown connector coming out of the back of the BCM. At that connector you should find a light blue/white wire. This is the wire that carriers the dedicated brake light signal. Use a circuit tester such as # PTW2993 to confirm...

  • 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.

  • Replacement for Malfunctioning Draw-Tite Activator Trailer Brake Controller
    Based on your description of the problem with your Draw-Tite brake controller I suspect an internal fault within the controller itself. There is a chance that the red input signal wire could be loose, and this would cause the unit to stop generating output, but it would not explain the varying power level displayed. That specific issue makes me think that the internal circuitry has finally given up the ghost and the controller needs to be replaced. I recommend the # 5504 in its place....

  • Troubleshooting Poor Brake Performance and Low Brake Output Voltage
    First thing I would check is the blue wire that is at the rear of your vehicle for voltage when you apply the brakes and when you slide the manual override of this controller. You could also try sliding the manual override a few times and adjusting the gain knob up and down to help clear the contact points. I attached a link to the manufacturers instructions for your Draw-Tite Brake Controller, part # 5504, below for you to check out also. If all this checks out it sounds like the problem...

  • Troubleshooting a Tekonsha Draw-Tite Activator
    It sounds like there is either a problem with the wiring of your Activator Brake Controller # 5504, the wiring of your vehicle/trailer 7-way or the # 5504 is bad. The first thing to check will be the 7-way of your vehicle. You will want to visually inspect the front and back of the connector looking for loose wiring or corrosion and fix as necessary. Next, you will want to test the brake output circuit of the 7-way with a circuit tester, like our # PT89ZR, for the correct voltage when...

    It sounds like you installed the Draw-Tite Activator Trailer Brake Controller 5100 in a vehicle with an integrated factory brake controller. If that is the case, installing an aftermarket brake controller like the Activator will cause the instrument cluster to flash the error code you mentioned.

You need the one that shows a signal ONLY when the brake pedal is pressed.

Check out the video that I made showing you how the brake controller should function without a trailer connected.

    Hi Vincent; have you tried checking the voltage at the brakes with a circuit tester # PTW2993? Perhaps one side has a weak ground compared to the other or for whatever other reason isn't getting the same amount of power. Since the brake controller sends power down a single brake output line and the brakes function I don't think the brake controller is your issue.

I have linked an installation video for the Redarc # RED44FR at the bottom of the page which will show you where the connector is and if you can wire it in using the Pigtail # 3063-P and Adapter # 331-TPH-017. As I see you were looking at the Prodigy P3 # 90195 it would only require the Pigtail # 3063-P which is long...

  • Brake Controller and Install Harness for 2022 Mercedes Sprinter RV
    The Redar Tow Pro Elite part # RED44FR can easily install on your 2022 Motorhome built on a Sprinter chassis with the part # 3063-P which plugs in right under the dash. This controller is really nice as it uses an inertia sensor to detect how hard you are applying the vehicle brakes and applies a similar amount on the trailer brakes. It also only requires putting a small control knob on your dash instead of a larger box like a traditional controller. I attached an install video for the...

  • Brake Controller Installation on 2016 Mercedes-Benz Sprinter
    Assuming your Sprinter has the factory tow package with the 7-way at the rear bumper, in addition to the # RED24FR Redarc Tow-Pro Liberty Brake Controller, you'll also need the # 3063-P wiring harness and the # 331-TPH-017.

  • Trailer Break Control Installation for Tekonsha Prodigy P3 on 2019 Mercedes-Benz Sprinter 3500
    According to my research, if your 2019 Mercedes-Benz Sprinter 3500 came with a factory 7-way trailer connector you will have the brake controller connector pre-wired.

  • How To Install a Brake Controller on 2017 Mercedes-Benz Sprinter 3500
    You can hard-wire in a brake controller, and it seems that there are not a lot of the Sprinter 3500 models that are pre-wired, at least from what I've seen in my research. I have not seen any reports that this isn't possible, and we even have an installation video to walk you through the process. The way to find out whether or not the plug is present by using a circuit tester like the # PTW2993 and testing for a hot wire when the brake is pressed- it's possible that one of the plugs that...

Then for a brake controller the Brake EVN # TK63VR would be a really great option that is very reliable and performs great.

  • Are There Instructions To Route Tekonsha Brake Controller Harness On Mercedes Sprinter 2500
    The Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3063-P which is a fit for a Tekonsha Trailer Brake Controller like the Prodigy P3 part # 90195 on a 2018 Tiffin Wayfarer Motorhome with Mercedes-Benz Sprinter 2500 Chassis does indeed plug-in under the seat. In order to route the harness up to the dash where you would ideally be mounting the brake controller you'd need to find a path free from moving components.

  • Where is the Trailer Brake Controller Plug on a 2020 Mercedes-Benz Metris
    The trailer brake controller plug on a 2020 Mercedes-Benz Metris is located on the driver side behind the center console, under the sound deadening mat in the top left of the passenger footwell. I have attached a photo of this as well.

If you don't want to do all the work finding the connector...

  • Parts Needed to Install Brake Controller on 2019 Mercedes-Benz Sprinter 2500 With 7-Way
    Since your 2019 Mercedes-Benz Sprinter 2500 has the factory 7-way, that means you'll have the factory tow package, so I assume by "wiring" you are referring to the wiring adapter needed to plug into the brake controller (it will plug into the green port under your driver's seat as in the accompanying photo). The correct part for your '19 Sprinter 2500 is the Tekonsha Custom Wiring Adapter # 3063-P. Then for a brake controller that works with that adapter, there are a couple options I...

  • Parts Needed to Install Brake Controller in 2023 Sprinter
    I checked with Tekonsha and a few other brake controller manufacturers and they state that your 2024 Mercedes Sprinter 3500 does not have an OEM brake controller install port under the dash like previous models so you would have to hardwire in the Prodigy P2 # 90885 with the universal install harness it comes with and the brake controller install kit part # 5506 which wires to the OEM 7-way you have.
