If you're looking for a trailer brake control module ...your search is over ...this is the one to get. This is my second Tekonsha P3. The first one recently suffered some form of electrical cardiac arrest ...after serving flawlessly for almost a decade. I didn't have to think twice about what to get to replace it.

The P3 is a proportional-type brake controller in that it responds to inertia; the faster you're slowing down the more it applies the trailer brakes. And after having tried a non-proportional controller the P3 is the bomb. Once installed, setup and adjustments are very easy following the instruction manual and using the four buttons on the face of the controller. The various setup menus display on the screen and there are some "troubleshooting" menus as well. You'll also get warning notices when things run afoul. You'll need to be connected to your trailer in order to make some of the braking adjustments. On the bottom of the module is a manual trailer brake lever functioning independently of the tow vehicle brakes.

If you're going to install this yourself, and have a late model pickup with a trailer package, then you'll want to score one of the pigtails to connect the controller to the under dash connector plug; the connectors come for all major brand pickups and SUV's. I suspect automobiles may use the same manufacturer adapter as for the trucks. You can install the unit "permanently" or using a quick disconnect bracket to allow you to easily swap the controller from one vehicle to another ...or just remove it and stow it in the included storage pouch. The unit has a memory and you can program up to 5 multiple trailer brake settings if you're going to be towing different trailers. The only "rocket science" needed in installation is making sure the controller is mounted parallel to, and as close to, the center line of the tow vehicle and parallel to the ground ...this is to ensure the inertia sensors in the unit operate and respond correctly. Fortunately the status screen is canted upward so you can easily see it when seated behind the wheel.

Once set up correctly the tow vehicle and trailer operate almost seamlessly and the stopping power of the trailer brakes is proportional to the rate of deceleration detected by the controller. Once you use one of these Tekonsha P3 controllers you'll never want another brand; it's that good. So stop looking, you found the one to get.

This brake controller was bought to replace a still working Tekonsha Voyager unit. The main reason I wanted to replace the Voyager is the 5th wheel RV we planned to buy, and eventually did buy, was/is equipped electric-over-hydraulic disc brakes on all 4 wheels. While some websites listed the Voyager as "compatible" with disc brake systems, the Tekonsha website does not make that claim. I chose the P3 after more research and finding LOTS of users proclaiming how well it works with a wide variety of trucks and trailer brake systems. It also has the ability to store your preferred settings for up to 3 different trailers and has 3 different levels of "boost" that applies trailer braking a little earlier than the tow vehicle's brakes, helping maintain control of the truck and trailer under most braking situations. It is a VERY effective trailer brake controller.

I used this with our 97 Ram truck with Cummins engine and 5-speed manual tranny, to tow our "new to us" DRV Mobile Suites RV from FL back home, traveling 4 days and covering 2100+ miles. In one particular situation I was SO glad I had the P3 brake controller when in a busy highway section running through a city and following a semi-truck and trailer, I couldn't see the traffic light ahead change to red. The semi-truck braked a LOT faster than I expected, requiring me to hit my brakes quick and hard so we wouldn't make contact. The Tekonsha P3 brake controller powered the RV's brakes strongly enough that combined with our truck's brakes we were able to bring the whole truck and RV package to a quick but controller halt with room to spare. Needless to say I was very impressed with its performance and how well it handled the RV's brake system in all situations, providing a level of confidence I really appreciate.

Bottom line is I HIGHLY recommend this brake controller to anyone who is or may be looking for a really well designed product. With the level of performance it has, along with the additional features it provides, I believe this has to be one of the best trailer brake controllers available anywhere.

I have used Tekonsha for decades on several campers over the years, and a few others that eventually got replaced with Tekonsha, the last one was the standard Prodigy. The P3 is a cut above the rest and the boost function is perfect for our 30 foot Cougar. The various color options allow to to change to match your gauge package. The install was super easy and under and hour with optional plug and play wire harness. Take it from experience, spend the extra few bucks and get the best brake controller because I have been in an Oregon Pass with a junk controller that came with the new truck we bought that about caused me to wreck. I installed the P3 and driving through the same passes was night and day difference!

So far, I have only installed the controller. I will update after hauling a load using the brake controller.
INSTALL; Very easy to install, assuming your vehicle is prepped for a brake controller. I simply connected the vehicle factory pig-tails to the included harness and crimped, added an electrical tape wrap to hold wires together and look pretty, picked my spot and two screws later its done! (Ok, I'm picky so I measured and remeasured, thought about it, and measured again. Took me 45 minutes to do, but the actual "install" was more like 10 minutes or less.)
Plug and play after that... Can't wait to get it set up for our new camper!

*Update- after hauling a large camper I can say this is a great controller! Having the proportional brake application made the vehicle tow in town almost like I wasn't towing. Adjustments to the amount of brake force were quick and easy. Definitely worth the purchase price and then some!

Tow vehicle:
RAM 1500 Hemi Lonestar Crew Cab

Parts used:
Tekonsha P3 Proportional Brake Controller purchased from Amazon

Tekonsha 3024P RAM Brake Control Wiring Adapter purchased from Amazon
(used to plug into factory installed wiring under dash)

Total Expense:
$151.45

My 2016 Ram 1500 Hemi Lonestar didn't come with the integrated brake controller. After searching all the RAM forums and studying Amazon reviews, I decided on Tekonsha P3 controller, and not to shell out the $440.00 my local dealership quoted to install the OEM. There's one video currently on YouTube that gives a breakdown how to remove the full length center console to install the OEM controller, but even then, you still have to have the dealer flash the computer so it all works together, and all the functions appear on the screen above the steering column. Some people are okay with this, but decided on the Tekonsha path myself.

I knew I wanted a clean, and minimally invasive install, so a little thought was needed to snug it up to my center console. In order to mount the controller, you have to have enough room to tighten the screws on either side. Instead, I used two very thin diameter toggle bolts I had left over, put them through the controller bracket with washers, screwed controller to the bracket, pushed the thin bolts through pre-drilled holes I made, and screwed the wings on from under the dash with some washers. This may not be the ideal way, but it worked great for me. All I can say is use this idea and improve upon it. :)

I might add before I started my project, I checked under the dash for the two factory installed connectors wrapped in foam tape. They're literally just hanging there and simple to find. This made it as easy as mount controller, plug n' play. Total install for me was about 30 minutes cause I was being careful.

After installing, it dawned on me there is no on / off switch. Back to the reviews and forums I went. Turns out there's controversy on this and weather it goes into a sleep mode or not. In my case, I checked 20 minutes later and the screen was blank as shown in picture. Starting the truck or touching a button wakes it up. Some reports from others is the opposite, and controller stays on. Either way, the power draw from the device is so little, it would take months to drain one's battery.

Setting up the controller for your trailer is pretty straight forward. As far as function, I'll be putting it to work next weekend for our 7,600 pound travel trailer. Just follow the directions, and you should be all good.

Hope this helps, and safe towing!

*** UPDATE ***
I can't think of a single complaint for this controller. Everything works in unison together as it should, and is easily adjustable. I included a picture we took on our way down to Galveston of the travel trailer when we stopped for a pee break. Gotta love Bucees!

I started with the boost on level 3, then turned it down to b2. It provides plenty of juice to the trailer brakes with the gain set where it's best for us now.
