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 on our 2013 GMC Yukon XL were going to install part number 90885 from Tekonshia. This is a P2 brake controller. The first thing we need to do is go ahead and locate the wiring harness for the brake controller. Now its wires that are located underneath the dash, off to the left hand side. Well go ahead and pull those down, and well go ahead and strip the wires and put on our bug connectors. Now well go ahead and hook up our wires.
The red wire with the black stripe will connect up to the black wire coming from the brake controller. Our brake signal will be the blue with the white stripe and will connect that to the red wire from the brake controller. Our blue wire from the vehicle will connect to the blue wire on the brake controller. Then our white wire will connect to a white wire, and that will be our ground. Well go ahead and use some electrical tape, tape the wires and make them nice and neat.
Then well go ahead and move onto the bracket to mount our brake controller. Off to the right hand side theres a small plastic flat surface at the very bottom. We can use that to mount our brake controller to. Well put our bracket up in place. Use a self-tacking screw to attach it.
We use two of these screws. Now go ahead and take our wire harness and plug it into the back of the brake controller. Then mount the brake controller to the bracket. All right. Were done with the inside of the vehicle now.
Well go underneath the hood. We have to hook up one more wire. Underneath the hood our pile wire is located between the fuse box and the fender. Well go ahead and pull out that wire and remove the lid for the fuse box. In front you can see theres two studs. Lift the handle up just a little bit so we can get some working room. Well take the ring terminal that matches the stud, and then use a nut to hold it down. Now, a nut is not supplied with the vehicle or the brake controller. The part number for the nut is 185917. Once its connected well go ahead and put the lever back down. Then well go ahead and check the brake controller. We can see we have two dots at the bottom, so we have power to it. Well go ahead and do a manual override. You can see it has NC for no connection. Well connect up a trailer and use the manual override again. You can see the numbers turn up, and then go back down and well release the lever. This shows that our brake controller is working properly, and that will finish it for our install. There you have it for part number 90885, the Prodigy P2 brake controller for a 2013 GMC Yukon XL.
