Ask the Experts about this Tuson RV Brakes Trailer Brake Controller

  • Will Tuson DirecLink Brake Controller Work with International Prostar Pulling 40 Foot Trailer
    Yes, the Tuson DirecLink Base Model Trailer Brake Controller # 335DL-100 will work well for a 40 foot trailer that is equipped with 2 axles. This unit is compatible with trailers that have up to 4 axles (8 total brake assemblies). The DirecLink will simply plug into the OBD-II port and the pigtail harness will need to be spliced into the appropriate wires on your truck (see attached image). For your International Prostar you will likely need to add either the Module Kit # 335HDCON-6PIN...

  • Compatibility of Tuson Brake Controller With 2016 Subaru Outback
    The Tuson DirecLink Base Model Trailer Brake Controller - 1 to 4 Axles - Proportional # 335DL-100 as well as the # 335DL-50 is compatible with the 2016 Subaru Outback. You will simply use # ETBC7 to add the 7-way connector, wiring, and circuit breakers. If you don't already have the 4-way wiring harness, then I recommend starting with # 118467. The difference is the # 335DL-300 has low speed brake adjustment.

  • Where Is the Brake Controller Port On An Entegra Coach Vision Motorhome
    The Entegra Coach Vision is built on a Ford F-53 Chassis which means there should be a pre-wired brake controller port under the dash. The exact location of this port can vary but most likely it will be on the left side of the steering column support which you can see shown in the attached photo. If you don't already have a brake controller in mind, the Tuson DirecLink Base Model Trailer Brake Controller part # 335DL-100 gets my approval as it is one of the most advanced controllers on...

  • Will the Tuson DirecLink Base Model Trailer Brake Controller Work On a 2020 Subaru Outback
    The Tuson DirecLink Base Model Trailer Brake Controller part # 335DL-100 will work on a 2020 Subaru Outback. However, it would require you to splice into the vehicle which is not what I recommend. Instead, I recommend the Curt Echo Mobile Trailer Brake Controller part # C51180 which is plug and play so no splicing is required. In order to use the Curt Echo, you will need the T-One Vehicle Wiring Harness part # 118467 with the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation...

  • Difference Between the Tuson DirecLink Base and Tuson DirecLink Lite
    The main difference between the Tuson DirecLink Base Model Trailer Brake Controller part # 335DL-100 and the Tuson DirecLink Lite Trailer Brake Controller part 335DL-50 is that the Base has low-speed brake adjustments and transmission temperature monitoring on Ford and GM vehicles. The low speed brake adjustments allows you to adjust the amount of braking that the DirecLink applies at low vehicle velocities such as in town driving. The Tuson DirecLink is one of the most innovative brake...

  • Troubleshooting Tuson DirecLink Brake Controller on 2009 Freightliner
    Just to make sure I am understanding correctly, you are getting the correct signals on the black, blue, red, and white wires on the Tuson DirecLink, like the Base Model # 335DL-100, but when you connect your trailer to your 2009 Freightliner it doesn't receive a brake signal from the controller. If this is the case then you simply need to test the wire that carries the brake signal from the controller back to your trailer. A typical 7-Way trailer connector should be receiving the brake...

  • How to Install the Tuson Direclink 100 on a 2011 Freightliner M2 102 DayCab
    I may have a solution for you, but I checked our resources and we're not showing any brake controller adapters available to install a brake controller on the 2011 Freightliner M2 chassis. In all likelihood if there is a plug in for a brake controller it's somewhere under the dash, but I really can't tell you where in this case or confirm that there is one on this chassis. With that said, since there is no adapter available, if you were looking to use the Tuson Direct # 335DL-100 you...

  • Will the Tuson DirecLink Controller Work With Pressure Transducer On 2006 Chevy Silevardo 3500
    The Tuson DirecLink Base Model Trailer Brake Controller part # 335DL-100 is an excellent top of the line option for a 2006 Chevrolet Silevrado 3500. It is a proportional brake controller which means it senses the deceleration of the tow vehicle and then applies a corresponding voltage to the trailer brakes. That said, this feature is controlled by an internal inertia sensor not a pressure transducer like your existing brake controller uses. The vast majority of electric trailer brake controllers...

  • Comparing the Tuson DirecLink Base and Lite Brake Controllers DL-100 and DL-50
    The Tuson DirecLink Base Model Trailer Brake Controller part # 335DL-100 and Tuson DirecLink Lite Trailer Brake Controller part # 335DL-50 are both excellent options The best option for you will be dependent on where you will be doing most of your driving. If you find yourself frequently traveling though town in stop and go traffic then the former which has the low speed brake adjustment feature would be a really good option but not necessarily required. If you are driving in stop and go...

  • Compatibility of Tuson DirecLink Brake Controller # 335DL-100 with 2006 Toyota Tacoma
    I spoke with my contact at Tuson regarding the DirecLink Base Model Trailer Brake Controller # 335DL-100 and your 2006 Toyota Tacoma. The potential issue with regards to fitment for this controller on trucks prior to 2008 is that not all of them are equipped with the factory 16-pin OBD-II port under the dash that this hooks up to. Many previous model year trucks do have this port but many do not, making it difficult to confirm fitment accross the board which is why Tuson lists compatibility...

  • Can Hayes Sway Master be Used with Tuson DirecLink Trailer Brake Controller
    Yes, the Hayes Sway Master # HA81775 referenced in your question is compatible with the Tuson DirecLink Base Model Trailer Brake Controller # 335DL-100. The Sway Master will just plug in line with the 7-Way connector on the trailer and won't affect operation of the Tuson brake controller at all. For this reason the Sway Master is really going to be compatible with just about any brake controller. This will give you a nice, safe setup with your tow vehicle and trailer to keep everything...

  • Parts Needed to Install Tuson Brake Contoller in 2007 Saab 9-7x
    You will need to start with a 4-way (if you do not have one) to install a Tuson brake controller # 335DL-100. For that you would want the # 119190KIT. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.
