Review of Tekonsha Brake Controller 90885


Today were going to review part #90885. This is the Tekonsha Prodigy P2 Trailer Break Controller. This is a proportional brake controller, which will activate your trailer brakes in proportion to your vehicles braking action. It will automatically adjust the trailers braking based on the deceleration of the tow vehicle, and it will activate immediately so theres no pausing like with your time-delay brake controllers. This controller does have an automatic leveling ability. Theres an internal sensor on the inside which will detect deceleration, even if the controllers not mounted flat.

You can position it at any angle, up or down in a vertical plane, 360 degrees, but you will want to be able to place it to where you can read this LED display right here. Now as far as horizontal position, you do want to stay horizontal and parallel to the direction of travel, so this way. In other words, not like this. Youll want it parallel that way. And not like that.

So as much as you can, and vertically you can go whichever way you want. Now there are three boost levels. Right here is the boost button. When you push that, it will put you into a boost 1, boost 2, or boost 3, and thatll let you adjust the initial braking power and aggressiveness, so if youre using a heavier trailer with a heavier load, youll want to increase the boost level. This controller also has a continuous diagnostic check, which will alert you to any potential problems.

It does have integrated safeguards, which will protect your vehicle, the trailer, and the brake controller. It does minimize drain on the car battery by drawing only 3.6mA when not in use. Itll prevent the trailer brakes from overheating by reducing power output to them during prolonged stops when your foots on the brake, and itll help defend the brake controller and the trailer breakaway system against any shorts. Right here will be the digital blue LED display, which is easy to read. Now in a minute here, Im going to hook the power up to it and well be able to see that.

On the very bottom here, which you can reach from the front, is a manual built-in rotary-style manual override for emergency braking purpose. Now on the very back, you can see the plug-in. It is a quick disconnect feature, which will let you easily remove and store the brake controller when not in use. It does come with this wiring harness that plugs into the brake controller and the pigtails to wire up to your vehicle. It does come with this type of mounting bracket, which will install with the mounting hardware to the side holes, or the popular pocket style, which you would mount this to your vehicle and then just slide this in, and on each side would be a pin that would slide into those mounting holes. To release it, you would just pull out those. It slides right out. There are also butt connectors to help you connect it to the wiring in your vehicle. We do also recommend that if you are going to move this from vehicle to vehicle, to buy an extra wiring harness and an extra bracket, if you dont use one of these. That way you have one in each vehicle and it makes it easier to remove the controller from one vehicle to another. We also do sell wiring harness that are vehicle-specific, meaning theyll have the plug like this n one end to plug into the brake controller. On the other end, instead of just these bare wires, theyll have a plug that will fit the factory brake controller port on your vehicle. What youll want to do is check the fit guide, if you do have the factory brake controller port, on our website and it will give you the part number of that vehicle-specific brake controller harness. This is designed for trailers with up to four axles or eight brake assemblies. It is designed for use with electric or electric-over-hydraulic trailer brakes. It does come with a limited lifetime warranty. Now what Im going to do is, Ive got a power source here Im going to connect the wires up to, so we can get an idea of that blue LED display and just some of the features. Ill show you how they operate on the controller. Ive got them all hooked up to the power source. Now Im going to snap this in. Im going to turn the power on. Now what youll see, is when the power comes on, youll see a C. Youll see a dot and a C. That means the trailer is connected. Now if the trailer wasnt connected, let me just disconnect this and Ill show you what it looks like, youll see itll flash N-C and that means not connected. Whatll happen is thatll flash for about fifteen seconds, then it will change to just the two dots, and that means you trailer is not connected. Ill show you here in a second. There you go. Now youre just seeing the one dot. Therell be two dots if the boost feature was engaged. If it isnt, theres just one dot. What were going to do is connect the trailer back up. There we go. Now youll see it is connected. Now this boost feature button right here, now youll see when I push it once, itll say b for boost. Now right now it isnt in any boost level, as youll see by just the dot and the C. Now when I hit boost and I go to boost 1, and then theres a boost 2 and a boost 3. When Im in a boost level, watch when that goes off, you should see a dot, a C, and a dot. Therell be two dots. That means the boost feature is engaged. Now to set the power, heres the power over here. If you push this manual override all the way on as far as you can go, and you turn that knob, and thatll set the boost or the power that you want. So lets say we set it at, lets say 6.3. Now I let off the manual override. So basically when you go to hit this manual override, as you push it, its going to ramp up and itll go all the way to 6.3. Thats the power you set it for. So you just set your power control, the dial there, by pushing all the way in and set the power. Theres a feature, if this is connected and its just sitting with no motion or activity for 15 minutes, it will go blank. It still has power connected, but itll go blank just to save on the power going to it. That should do it for the review on part #90885, the Tekonsha Prodigy P2 Trailer Break Controller.
