Arrives before Christmas To see if this custom-fit item will work for you please tell us what vehicle you'll use it with.
The Tekonsha P2 is a classic brake controller you know you can rely on. It's easy to install, and with the custom harness, it's plug-and-play.

Specs:
Gain 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.
You can adjust the gain by turning the thumbwheel on the front of the controller.
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 gain. 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 Prodigy P2 offers key safety features to prevent damage to 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 draws only 3.6 milliamps to minimize the 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.
The Prodigy P2 also runs continuous diagnostics to check for problems as they come up, including:
Installing the P2 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 P2 must be horizontally level and parallel with the direction of travel to work correctly.
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 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'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.

Today in our 2006 Ford Expedition, we'll be installing the Contra 00:02:35 Prodigy P2 Break Controller, part number 90885 with a direct fit wiring harness or pigtail 00:00:11, part number 3035-P. First we'll go ahead and locate the manufacturer's break controller tow hood. Here, next to the diagnostic link for the vehicle's computer, we'll find the gray, five pin plug which will be the manufacturer's tow port. Next, we'll take the break controller bracket and find a suitable mounting location. Then using the hardware provided with the install kit we'll go ahead and secure the bracket in place. Next, we'll take the wiring harness, plug into the gray connector on one side and route the other up through our break control bracket or pocket. Once we have our harness in position, we can then go ahead and take the wiring harness and plug it into the back of the break controller. Once we have it plugged into the break controller, we can then go ahead and put our break controller into the pocket and lock it down.
Now with everything installed, we'll go ahead and secure the excess wiring up underneath the dash. We'll use a zip tie to secure the wiring, cut up the excess from the zip tie, and clean up our install look. Now, with everything installed and secured we can go over our basic break controller operation. Currently, we show that we have break control power, then when we plug in our trailer we'll get a C to show that we've connected our trailer. Then when we unplug our trailer it'll flash NC, showing no connection. With our trailer break connected, we can press on the break pedal.
It will send power to our trailer breaks and the numbers on our break controller will go up as the pressure increases. Using thumb wheel on top, we're able to adjust the sensitivity of our break controller. The manual sweep on the bottom of the break controller is for manual breaking. It will increase the pressure to the trailer breaks without using the vehicle breaking. With that, we're ready to hit the road, and that will do it for the install of the Contra 00:02:41 Prodigy P2 Break Controller, part number 90885, in the conjunction with the Contra 00:02:45 Direct Fit Wiring Harness, part number 3035-P on our 2006 Ford Expedition.
