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.

Today on our 2000 Ford Expedition, we're going to install part number 90195, the Prodigy P3 Brake Controller. We'll be also using an Adapter Cord, part number 3035-P from Tekoncha. We'll start off with that part. We'll look for the port that's underneath the dash. It's right next to the diagnostic port. You'll go ahead and point it out and then go ahead and plug the cable into it. All right.
Now we'll go ahead and take the other end and plug it to the back of the brake controller. We'll set that down for now. Then we'll go ahead and attach a bracket to the bottom of the dash. First we'll go ahead and do a test fit. Well put our bracket onto our brake controller and then mark our location where we want it. Then we'll take our smaller bracket and go ahead and attach it to the dash.
We'll be using two sheet metal screws. We'll go ahead and drill into the dash. Now you want to be careful. There's some metal right behind the plastic so be careful when you drive the screws in. Once our bracket's installed, we'll go ahead and take our brake controller with this bracket and put the two together and run another sheet metal screw on each side to hold them in place. At this point we'll go ahead and use some zip ties and keep our controller wire out of the way. All right.
With that, our brake controller is already installed. Let's go ahead and try it out. We read the manual override. We can see it says, "No trailer connected." This is a display of bright red signal. Okay.
Now we'll go ahead and plug in our trailer and you can see how it changes to showing a truck and trailer and some numbers on the bottom. Okay. We'll move the manual override and we'll see how it scrolls through the numbers. Next we'll go ahead and push the brake pedal and make sure it works. We push it and it shows a 2.2. That tells us we have signal from the brake switch. Okay, and with those few steps, our brake controller is already installed. There you have it for part number 90195, the Tekoncha P3 Brake Controller and our Adapter Cord, part number 3035-P from Tekoncha on our 2000 Ford Expedition. .
