Specs:
Braking 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.
Use the arrow buttons on the front of the module to set the output.
The boost setting 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.
Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set braking output. So instead of starting at 0, the brakes will start at 25 percent and get to 100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.
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.
To engage the manual override, twist the rotary-style lever from right to left. This will activate the trailer's brakes and brake lights independently of your vehicle, great for stopping sway or controlling your trailer's momentum in an emergency.
The P3 is able to store your settings in multiple profiles so that you can have them ready to go for different trailers and drivers. Even the display is super customizable: you can change the screen color, brightness, and language to make it easy to use.
The P3 makes it easy to troubleshoot problems as they come up, with comprehensible and detailed diagnostics displayed on the screen.

Diagnostic warning signs include:
The Prodigy P3 offers advanced 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 P3 is not in use, it draws only 3.6 milliamps, minimizing drain on your vehicle's battery.
-Any time your 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 without your brakes overheating.
Installing the P3 is incredibly simple. You'll mount the bracket to your dashboard then mount the unit to the bracket. Plug the custom harness into your vehicle and into the unit. Done!
Keep in mind that the P3 must be horizontally level and parallel with the direction of travel to work correctly.
With a replacement wiring harness (sold separately) and replacement bracket (TK5906 - sold separately), you can even transfer the Prodigy P3 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 means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes, 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 and trailer.
The Prodigy P3 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.

Speaker 1: Today on our 2007 Toyota Tundra, we're going to be taking a look at and showing you how to install the Tekonsha Prodigy P3 Proportional Trailer Brake Controller for one to four axles, part number 90195. To help us get that installed, we're going to be using the Tekonsha Plugin Wiring Adapter, part number 3040-P. This is what our brake controller looks like when it's installed. What this is going to be good for, it's going to allow you to apply the brakes in your trailer whilst being towed. In turn, saving the brakes in your truck so it doesn't have to stop the trailer, the trailer's going to be able to slow itself down.These arrows right here on the left side, these are going to be your gain setting. You can see it goes up to 14 and goes all the way down to zero.
Now this is going to allow you to set the maximum amount of output or amount of output that you're wanting to apply to your trailer brakes. This is going to be a proportional brake controller, which means it's going to have a sensor inside that's going to detect the deceleration of the truck and apply the appropriate amount of braking force to the trailer. For instance, if we're in an emergency situation and we had to slam on the brakes in the truck, that sensor is going to detect that, it's going to send that amount of force to the brakes in the trailer, slowing that trailer down. In turn, saving the brakes in the truck.This button here is going to be for your boost. Now, your boost setting, you're going to have three and then you're going to have an off boost.
Now, in your boost set off, that's going to be for a lighter trailer, maybe a small trailer that's unloaded. The higher the trailer weight in reference to the weight of the vehicle. For instance, if you get a trailer that is the same weight as the vehicle, you are going to probably want to be boost two. When the trailer weight goes over the weight of the truck, you're probably going to want to be set at boost three. What the boost is going to do is that's going to adjust the aggressiveness of the braking force sent to the trailer brakes.
Again, saving the truck brakes from having to slow that trailer down.This button here on the bottom, this is going to be the manual override. Now, whatever your gain is set at, it's going to go to that amount. What the manual override is for is for instance, you're going down a hill and your trailer starts to go offline a little bit or you have an emergency situation and your trailer's swaying, you can apply the brakes in your trailer without having to apply the brakes in the truck. That's going to help you get the trailer back center, back behind the truck to help you gain more control.What's going to set this brake controller apart from others is it's going to have a customizable LCD display. It's going to allow you three different languages and colors to choose from.
It's also going to have five storable settings for different size trailers or different trailers that you may be pulling. You're going to be able to select electric over hydraulic or electric trailer brakes, but what I really like about this brake controller is instead of this just giving you just a signal, this is going to actually put words on the screen. If your brake controller or your trailer is not connected or comes disconnected, it's actually going to tell you "No Trailer Connection" on it.You can change your brightness, your color, and your contrast. This is where we change our brake type, electric and hydraulic. Now, as far as this installation, it is very simple and straightforward. Now that we've gone over some of the features, let's show you how to get it installed. To begin our installation, we're going to take the white end of our adapter plug and we need to find the matching in. Now if you look right up here behind the emergency brake pedal, right above this panel, you'll see a plug. Very easy to get to. We're just going to take our white ends and plug them in together until you hear it click.Next thing we need to do is we need to mount our ground wire. Now what I like to do is try to find an existing nut that is mounting to the body, make sure it's on metal. You look right here behind the emergency brake pedal, there's a nut. You can see our ring terminal is just a little bit too small, so what we're going to do is we're going to replace that with a bigger one. This is a ring terminal for our 10 to 12 gauge wiring. We'll cut off this one. Trim this back and we'll crimp it down. Give it a little tug, make sure you've got a good connection. And we'll take 1/2" socket with a fairly long extension and get that nut off. Add our ring terminal and then replace the nut.Next, I'm going to route my adapter. What I want to do is I want to find some existing wiring up inside here that I can zip tie or secure it to. I'm going to run it across. You want to make sure it's over on this side of the steering wheel. The reason you want to stay away from this side is when you're getting in and out of the truck you take a chance of damaging it or hitting it and knocking it off. Next, I'm going to take my wire, I'm going to take some black electrical tape and I'm going to cover up my wires, just kind of help it blend in with the brake controller itself. To kind of make it look nice.Next, we're going to mount our bracket that's going to hold our brake controller onto our dash. You see our customer had something preexisting her had here, so what we're going to do is we're going to use his same holes and we're going to make sure that I'll be able to put my bracket there. It looks like we'll be able to fit it. We're going to take the screws that comes in our kit with our brake controller and fit in place. Now we can mount our brake controller to our bracket with our provided screws. Once we have it installed on our bracket, we'll plug it in. And as you can see, we have power.And the screen's red. It says, "No Trailer Connected." Once we've connected to our trailer, you'll see a little truck with a trailer behind it. Once you see that screen, you're ready to go. And that'll do it for our look at and installation on the Tekonsha Prodigy P3 Proportional Trailer Brake Controller, part number 90195 on our 2007.
