Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner. Just set the initial power level, select a boost setting, and you're good to go.


As long as the Prodigy controller is mounted properly and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.


Power Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, Tekonsha's Prodigy brake controller also offers a boost feature that gives you more initial braking power for those times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 13 percent or 25 percent of the predetermined power setting.


So, if you boost the initial power so that your trailer brakes activate with 25 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.


If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.


Approximate Gross Trailer WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicle GVWB113%
Equal to tow vehicle GVWB1 or B213% or 25%
Up to 25% more than tow vehicle GVWB2 or B3*25%
Up to 40% more than tow vehicle GVWB3*25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.


Safety Features

The Prodigy offers advanced safety features to prevent damage to various components of your towing setup. When the controller is not in use, it will be in power-saving mode. In this setting, the power draw falls to only 3.6 milliamps, minimizing drain on your vehicle's battery.


When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for more than 5 seconds, the Prodigy's "hold" feature will activate. When this happens, the power output to your trailer's brakes will be reduced to just 25 percent of the preset power setting so that the brakes will not overheat.


If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override lever is easily accessible. Pushing this lever engages the brakes on your trailer with full power. In addition, when you activate this override, the brake lights on your trailer will illuminate, properly warning those behind you of the braking action of your rig.


In addition to all of those safety features listed above, the Prodigy offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-leveling feature of the Prodigy ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at a vertical angle that is between 0 degrees (level) and 70 degrees, and the controller will level itself automatically.


Correct Prodigy mounting70-Degree Prodigy mounting

Note: The Prodigy must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.


Installation is a snap. After mounting the Prodigy unit in your cab using the included pocket mount, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To transfer the Prodigy to another vehicle or to remove it for storage, just unplug the unit and slide it out of the pocket mount.


Installation Accessories

For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.


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 Tekonsha Prodigy Trailer Brake Controller Review

Today we are going to show you part number 90185 from Tekonsha. This is their Prodigy controller right here. This is actually Tekonshas most popular brake controller, the Prodigy. And this is what you get in the box. Obviously you get the brake controller itself. Then you get the pocket that holds the brake controller especially if you have to transport it between 2 different vehicles. You also get the permanent mounting bracket which is actually nice and takes up less room. You also get the hardware to install the brake controller to the dash and to the bracket. A few butt connectors are in there to use for any wire connections. Speaking of wiring, it comes with a universal wiring harness that will plug into the back of the brake controller then you run your lines to the various circuits in the vehicle. Also to help you out it comes with a little informational DVD.

What we will show you next is the actual pocket that you can install on the vehicle, it actually mounts up like this. The brake control simply just slides inside. Spread the little clips out a little bit and it goes into the screw holes and that pretty much holds everything in place. On the backside here is where the harness plugs into. It is pretty simple. Slip it underneath the holder and you just push it together and it snaps in place. So in other words, if your are going to go ahead and share this brake controller between two different vehicles, you just simply take it our of the pocket, pull it out of the pocket, and take the harness back off of this little clip that is kind of hard to see. Pull that clip back and it pops off. And then this stays in your truck and the brake controller stays out of the way when you are not using it. Next we will show you the unit in operation.

That means, obviously, it is not hooked up to a trailer. And what this does is actually send out a trace current all the time looking for a connection. It does not take much current, it is real slight and it will never drain down the battery. Once you do have a trailer hooked up, it will show a C for connection. That tells you you have a solid connection between your trailer brakes and everything should be working fine. And with talking about the power settings and the gain, that is controlled by this knob right here. And what you can do is put it over to the middle here and you can spool it towards the front of the vehicle, that will be basically full on, and then rotate it back towards the rear of your vehicle, towards the driver seat. And then, you can spool it down all the way to basically nothing. Basically, you want to set to probably somewhere in the middle, like around six. And then you take your trailer, hook it up, go on a back road somewhere or a big packing lot and take a few test runs. If you need more power you can spin the wheel up. Basically you want to spin it up before a brake or right before the wheels actually lock up. And then, if it locks up at the original setting, then you just spool it back down just a little bit. And then again you want to get it right before lock up. And then you leave your setting alone and basically the brake controller takes care of the rest.

And when installing the brake controller, you have about 70 degrees of movement. So it can be from about roughly about here to about here of angle you have to install on the brake controller. And if you do go past these angles you will see two bars flashing at the bottom there, that tells you that it is pointing down too far. The same thing will apply if you put it up too far, we will say about 90 degrees. It will take a few seconds to show the bars on top too. And then to show you how this works, basically the brake controller works by inertia. There is a little pendulum of movement inside here that actually, when you hit your brakes, it actually slides to the front of the vehicle. The more that pendulum moves towards the front, the more power this brake controller puts out. And then, say you hit your brakes pretty hard it is going to apply the brakes pretty hard.

If you let off the brakes gradually, this will follow in turn. When you hit your brakes, if you have one of the boost settings set on it, it will come on. Again it will say like B2, it will come on 25 percent, almost instantly. And then, it will hold that power for a second and then it will revert back to inertia so you have smooth braking until you come to a complete stop. The boost setting is really nice if you want the brake controller to activate the brake, or the truck actually does a lot of its own braking power. It is kind of hard to show the inertia activated on this brake controller but we will try. Basically, we will just move it a little bit, make the pendulum work and you can see how it puts out numbers and goes back to zero once it is stopped. So you are connected and then you hit your brakes and it is saying zero right now because it does not sense anything. And then, when you back up, it will fill up a little bit with numbers and then go back to zero. And there you have it for part number 90185, the Tekonsha Prodigy brake controller.

Easy, reliable, and intuitive I had never towed a trailer before and I knew nothing about trailer brakes before I bought the Prodigy. The installation is straightforward. Run power to the unit from battery through 30A breaker, hook into the brake switch wire, connect to ground (preferably direct to negative battery terminal) and one wire to the trailer connector. Calibration and setup is quick and easy. It can be mounted at an angle and does not need to be level or adjusted to level. Tells you what's wrong if something's not working. Braking is smooth and consistent, proportional to the vehicle. No tricky wiring or weird contraptions for reversing. Can be moved from one car to another with a replacement pocket and wire harness. I don't know how it could be much better unless it did the driving for you. My only gripe, and it's a very small one, is that the adjustment wheel you use to set the braking level can be a little touchy. This is a very good brake controller for only a little more than a time-delay or weight-driven type, so I don't know why you would even want one of those. Buy the Prodigy instead and get the best attributes of them all. 648

Great purchase! I have never had trailer brakes before, my neighbor let me use his enclosed tandem axle trailer to pull behind my 2003 ford ranger 4wd ext cab. The trailer has brakes on it. He told me i could pull it without using the brakes but that it takes longer to get it stopped and even worse when loaded down. I am so glad I spent my money to get this and a install kit to put this on my truck. It made a huge difference in pulling it especially loaded up. It is also nice to use the trailer seperate brake to slow down faster if needed, this was something my neighbor showed me. If the trailer has brakes on it, be sure to get a good controller, dont be cheap! its worth the money!! Take your time to install it! You can be just as professional as the shops that charge a bunch to do the same work. 2293

Great product, easy to install I purchased a Tekonsha Prodigy for my 2009 Ford Ranger Sport. I installed it in a couple of hours by myself following the included guide. I had to do a little homework, the brake switch wire colours (Violet/White)for the 2009+ Rangers are different than the earlier models. I used a digital voltmeter to be sure I was using correct wire from the brake switch. The 2009+ Rangers only come with a factory four wire trailer connector, however the install went flawless following the included directions on additional wires to run to my 7 pin adaptor I bought separately. I saved nearly $100 ordering it through the US with the exchange rate at par on the CDN dollar. I am very satisfied with my purchase and look forward to pulling my new tent trailer. Thanks ETrailer! 3013

What a difference! I tow a 5x8 utility trailer with a Subaru Legacy sedan...I only pulled it once before installing the Prodigy, and I'll never go back! Once it's installed, the Prodigy is very easy to adjust on the fly and works amazingly well! It's a relatively small unit, and doesnt look out of place in the car. I was nervous about it draining the battery because I only use the trailer a few times a month... but i've had no problem at all...it shuts itself off after 15 minutes of not touching the brakes. Great stuff, look no further! 2713

great product !!!!!! I recently purchased a hitch for my 2009 Nissan Frontier and the installation was a breeze. I decided to order the Podigy brake controller and do it myself. The truck did not have factory tow package, therefore was not prewired. I was a little worried because the truck was BRAND NEW. Everything went smooth. You customer support was great (Pat C).Videos helped too. These people know how to get it done. Iwill be back to E-Trailer for all my needs. Thanks again. AAAAA++++++++ Service 1668

Saved my butt! Second time towing the camper (Starcraft Antigua 215SB w/ 2005 Trailblazer) the idiot in front of me slammed on his brakes because he missed his turn. I thought there was 0% chance I would make the stop. I would say this unit stopped me as well as the truck would have stopped not towing anything. This works extremely well and was very simple to install myself. Highly recommended. 2212

It is very easy to use and it brakes very well and without any tendency to lock up at all.

Far superior to timed units. Connections very straight-foward, quick setup and learning curve. Performance is nothing short of wonderful! I have been using Activator II controllers until now, I will never go back to a timed unit again. I really have nothing negative at this point to say, just returned from 1400 miles of towing. 2325

  • What are the Differences Between the Prodigy P3 and Primus IQ Brake Controller
  • There are quite a few differences. The ones you can see easily on the outside are the display and control buttons. The P3, part # 90195, uses a multi-color LCD to provide more information where as the Primis IQ uses basic LED numbers like what you would have on your digital alarm clock. The P3 uses a rotary lever on the underside for a manual over ride where as the Primus uses the older slide design that some people have problems with the slide sticking depending on how they grip and...

  • Comparing the Tekonsha Prodigy Brake Controller # 90185 and Prodigy P2 # 90885
  • There are 3 big differences between the Prodigy, # 90185, and the Prodigy P2, # 90885, brake controllers. The most notable difference is the LED display is blue on the P2 where as it is red on the Prodigy. The second difference is that the P2 can be mounted at any angle, a full 360 degrees, where as the Prodigy needs to be between level and 70 degrees nose up. The third big difference is that the P2 can be used with electric over hydraulic systems. A couple minor changes include some inherited...

The P2 has a brighter, light-colored LED display that is easier to read than the red LED display on the Primus, and the P2 also features a rotary lever for the manual braking feature, while the Primus uses an older style...

  • The N.C. error code on the Tekonsha Prodigy Brake Controller, # 90185, could be indicative of several problems or a combination of problems. Since it shows the code with the trailer connected, it could be a short or open circuit on the brake output wire. There could be a missed connection or a bad ground causing the circuit to not be complete. Though the problem is most likely on the trailer side, checking the wiring on the truck is also a good idea.

The breakaway is designed to work when the trailer has detached from the vehicle so the electrical connection would be severed. Most Brake controllers are protected from back feed so if you did test the breakaway with the trailer connected you should...
