Gain Power Adjustment

Tekonsha Prodigy P2 gain

You can adjust the gain (also known as output) with the thumbwheel on the front of the controller. Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. A heavier trailer will need more power to achieve smooth, safe braking, while a lighter trailer will need less. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes.


Power Boost for Heavy-Duty Towing

The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.


Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set gain. What this means is that, instead of starting at 0, the brakes will start at 25 percent and get to100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.


If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.


Boost Levels:

Approximate Gross Trailer Weight Boost Level Increase in Initial Power Output
Less than tow vehicle GVW B1 13%
Equal to tow vehicle GVW B1 or B2 13% or 25%
Up to 25% more than tow vehicle GVW B2 or B3* 25%
Up to 40% more than tow vehicle GVW B3* 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 P2 offers key safety features to prevent damage to various components of your towing setup. Integrated reverse battery protection shields the brake controller and your trailer's breakaway system from shorts. When the P2 is not in use, it will be in power-saving mode. In this setting, it draws only 3.6 milliamps, minimizing drain on your vehicle's battery.


The P2 also comes equipped with a hold feature to prevent wear on your brakes. When you're waiting at a red light, you don't need your trailer brakes on at full power. The longer you sit there, the more they will overheat. But with the P2, any time your tow vehicle and trailer are at a standstill with the brakes applied for more than 5 seconds, the hold feature will kick on and reduce power to just 25 percent. This will keep your trailer in place while saving your brakes.


The P2 keeps the manual override within easy reach, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just twist the rotary-style lever from right to left. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.


The Prodigy P2 also 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 P2 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 any vertical angle, and the controller will level itself automatically thanks to its 360-degree rotational range. This makes the installation that much easier. But keep in mind that the P2 must be horizontally level and parallel with the direction of travel to work correctly.


Prodigy P2 correct mounting

Installation is a snap. After mounting the P2 unit in your cab using the included bracket, just plug the custom harness directly into your vehicle. The other end plugs into the brake controller. To remove the P2 for storage when you're not using it, just unplug the unit and slide it out of the bracket. With a replacement wiring harness (sold separately) and replacement bracket (P7685 - sold separately), you can even transfer the Prodigy P2 to another vehicle.


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 controller installation kit (ETBC7 - sold separately).


Proportional Braking

What is proportional braking

The Tekonsha Prodigy P2 brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.


The Prodigy P2 uses an internal inertia sensor to detect how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Video Transcript for Choosing Between Tekonsha Brake Controllers

When it comes to choosing a brake controller, a lot of them are gonna look very much the same. And two of them that I really like are from Tekonsha. We have the Prodigy P2 and the Prodigy P3. So, they look very similar, but they do have quite a few differences and we're hoping to break that down, that way you can decide which one's best for you. Here we have our P3 installed and really it comes down to it has more bells and whistles than the P2, otherwise it's pretty much the same controller. The P3 does have a nicer/easier to use display.

It's a little bit more user friendly. It uses some icons here that, you know, show you a trailer and that way you know pretty quickly what boost level you're at and it's really easy to read. It's a nice digital display and you can change a lot of that. Also, it has a little bit more diagnostics. So as far as, instead of just having error code with the P2, this one will actually tell you exactly what it is and there's a host of diagnostics so that way you can look at it.

You won't have to troubleshoot the code by looking at the owner's manual. It'll tell you right away what's happening. The P3 is also really nice if you have a bunch of trailers in your fleet, you can set up presets, up to five of 'em, and that way when you hook up to said trailer, you can select that and it's gonna be preset to the boost settings and also the gain that you may have dialed in. That way you just hook up and you'll be ready to go. Multiple trailer settings are gonna be nice, especially if you have a work truck and you're hooking up to a bunch of different trailers, you can get that dialed in, but if you tow the same trailer over and over, or you know that you're only gonna have one trailer long term or maybe two, that's really not gonna be a function that is necessary.

Now with the P2 installed, you can see right away that the display is obviously not as fancy as the P3, but you again have all the same functionality. There are less buttons, so that kind of keeps it simple. If you just need a brake controller, this is a great option. You still have your power knob, you have your boost button, and you still have essentially the same manual override, which I do like on the Tekonshas, you have a nice modulation here. But really when it boils down to it, they are very, very similar.

The size is gonna be almost identical. They're gonna mount up the same, they're gonna install the same. Again, you have that same proportional here. They both work for one to four axles. They're both proportional. So pretty much the same thing, just more bells and whistles on the P3. If it's something that you're gonna wanna keep for a long time on your vehicle, a P3 is pretty sharp. I do like the display, and something to think about too, you can always take a brake controller from one vehicle to the next, so, but if you're just need to tow a trailer and you need a brake controller, P2 you're not gonna go wrong with. I just like the fact that there is diagnostics that are a little bit more straightforward with the P3. And if you're worried about if it's gonna work with your trailer, they're both gonna work with the same kinds of trailers. You can have electric brakes, you can have hydraulic brakes, it doesn't matter. These are gonna work with either one. So hopefully this video helps break down some of the similarities and differences to help you decide which Tekonsha Prodigy Brake Controller is gonna be best for your needs.

    Hey Jim, so there is a brake controller plug in harness on your 2022 Ford F-53 motorhome that you can use to install the P2 part # 90885 that you have but we don't have a plug-in style adapter for it. So what you'll have to do is cut off the harness on the motorhome as well as the connector on the brake controller harness and hardwire the two together.

  • 2018 Ford F150 With Factory Brake Controller Has Weak Signal When Brakes Are Applied
    Hello Rick. The brake controller uses just one wire to send braking signal to your trailer. So, if the manual override is working fine, I do not suspect an electrical issue. It sounds like the gain setting on your brake controller got turned down somehow. Can you try adjusting the gain setting and changing it to a higher level? Do this and you should see stronger braking like you do with the manual override.

The Blue Ox systems work decently but in terms of sway reduction, ease of install, and reliability the Equalizer is the way to go. You would want the part # EQ37120ET which would work great on your trailer that weighs 7,500 lbs. It comes with a hitch ball but you would need the thin walled socket part # ALL643216 to install it.

    To install the Prodigy P2 part # 90885 in your 2015 Toyota Tacoma the install harness part # 3040-P is the correct one to use. The plug in a Tacoma is extremely well hidden. It is high above the driver's side kick panel taped behind a plug wrapped in foam. I have attached a photo to help you locate it in a late model Tacoma. It's the white connector.

  • Recommended Trailer Brake Controller and Wiring Needed for 2000 Toyota 4Runner
    For your 2000 Toyota 4Runner, I recommend the Tekonsha Voyager Trailer Brake Controller - 1 to 4 Axles - Proportional # 39510 with the Brake Control Plug-In Harness # 20127. This is the best controller under the price point you are seeking. Then for your wiring, if you already have a 7-way connector you can use the kit # 5506. If you have a 4-way then you will use the # ETBC7 kit which comes with the 7-way adapter and wiring. If you don't have a 4-way, then you will need that first and...

  • Brake Controller Installation on 2011 Toyota Tundra
    If your 2011 Tundra has the factory tow package, which includes the factory installed 7-way trailer connector on the rear bumper, it will be equipped with the tow package plug under the dash, as shown in the photo I've edited for you. Some models with the factory 4-pole (or 4-pin) trailer connector will also have the plug under the dash, you'll need to look for a white plug located above and to the left of the emergency brake pedal, above the toe kick. Occasionally, the plug will be located...

  • Parts Needed to Install P3 Brake Controller in 2017 Toyota Highlander
    If you have a factory 7-way on your 2017 Toyota Highlander you'd have to hardwire the controller to the vehicle as there isn't a factory port, but if you didn't have a factory 7-way we offer a solution that fits your vehicle and comes with a plug that attaches directly to the back of your P3 part # 90195 with the 7-Way kit part # 22119. For a wiring kit to install the brake controller to a factory 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506....

  • What Parts are Need to Install a 7-Way on a 2007 Toyota Tundra
    If your truck came with a factory 4-Way connector, you will need to use part # ETBC7 to add a 7-Way at the rear of the truck. You will plug the lead off the 7-Way into your pre-existing 4-Pole. You will then have to hardwire the other 4 loose leads. White is grounded to truck frame, black is ran to the battery with the included 40amp breaker wired in line. Blue is run up to the cab on the truck and is connected to the blue wire on your brake controller. The purple wire is for reverse lights....

  • Location Of Brake Controller Connector In 2003 Toyota Land Cruiser
    If your Land Cruiser was equipped with the factory installed 7-way trailer connector at the rear bumper, it will have the brake controller connector located under the dashboard. The connector will be taped to another wiring harness somewhere near the top of the emergency brake pedal. The connector will likely be covered with tape, so it could be difficult to locate. If you find a big ball of tape wrapped around a wiring harness, you've probably found it. The # 3040-P you've referenced is...

  • Brake Controller Installation in 2015 Toyota Tacoma
    The # 3040-P is indeed the correct brake control wiring adapter for your 2015 Tacoma. Due to the presence of the knee airbag, the preferred location to the right of the steering column might not be feasible. If there's not a suitable location to the right of the steering column where the controller could be mounted so that it's parallel to the direction of travel, you'll need to consider an alternate spot. If you watch one of the videos I've linked you to, you can see the controller being...

  • Suspension Enhancement Recommendation for 2008 Toyota Sequoia Towing Trailer
    The Timbren kit part # TTORSEQ1 that you referenced is the correct fit for your 2008 Toyota Sequoia and would give you additional suspension support when towing. That said I wouldn't necessarily recommend this kit unless you were planning to be towing most of the time as it would make the ride quality a bit harsher when not towing. The better option if you are concerned about ride quality is the part # F4164 which allows you to use varying air pressure in the bag so that you can tailor...

  • Troubleshooting Hopkins Impulse Trailer Brake Controller Error Message OE
    The troubleshooting guide for the Hopkins Impulse trailer brake controller does not list an error code "OE" but if the unit displays a flashing code "SC" this indicates a short on the brake output circuit or a defective brake magnet, which is unlikely on a new Aliner. Those error codes can sometimes be difficult to read. My Hopkins contact said much older versions has error codes E1, E2, E3 but not OE. I suggest taking a close look at your Tacoma's trailer connector. Corrosion issues on...

  • Brake Controller Connector and Recommendation for a 2005 Toyota Tacoma with Tow Package

If you have the accessory panels on your truck you can also use the Mounting Panel # 331-TPSI-007 to give your install a custom look.

    The only way to verify if your 2006 Toyota Tacoma will accept the Tekonsha Plug-In Wiring Adapter # 3040-P is by finding out if it came with the factory tow package. We have only installed this on one 2nd generation Tacoma in our shop and it was a 2012. I have included a link to the installation video below where they install the Tekonsha Prodigy P2 # 90885.

  • What is the Correct Brake Controller Wiring Harness for a 2013 Toyota Tundra
    Yes, if you are using a Tekonsha brake controller then you will use wiring harness # 3040-P. I have included a link showing a typical installation for you. The extra ground wire must be attached to a bare metal surface to complete installation because the factory Toyota ground is not sufficient for the brake controllers needs. This is a plug and play type of harness. One end plugs into the controller, the other end into the factory connector. No splicing required for installation.

  • Which Tekonsha Prodigy Brake Controller for 2011 Toyota Tacoma with Factory Tow Package
    There aren't going to be any real functional differences between the Prodigy P2 # 90885 and the Prodigy P3 # 90195; both provide proportional braking and both have a 3 axis accelerometer so that they can be mounted in a 360 range vertically and still sense the braking in your truck. The Prodigy P3 has a nicer LCD display and it's a bit easier to cycle through the different settings and functions, so I do recommend going with the P3 # 90195. If you're looking for an entry level, no frills...

  • Parts Needed To Install Prodigy Brake Controller on 2012 Toyota Tundra
    The brake controller will not be a 7 pin or 4 pin, it is the trailer connector that is at the back of your vehicle that will be either a 7-Way connector or a 4-Flat connector. To use a brake controller like the Tekonsha Prodigy P2 Brake Controller, part # 90885, on your 2012 Toyota Tundra you will need to have a 7-Way trailer connector at the rear of your vehicle. The 7-Way is required to give you the additional leads that are needed for the electric brakes, 12 volt hot lead, and backup...
