How to Install a Trailer Brake Controller on a 2012 Ford F-150


Today, on our 2012 Ford F-150, we're going to be taking a look at and also showing you how to install the Tekonsha Primus IQ Trailer Brake Controller. This proportional brake controller works for 1 up to 3 axles. The part number on it is TK90160. We're also going to be using the Tekonsha plug in wiring adapter for brake controllers, part number 22292. As a built-in safeguard, we've got constant monitoring of our trailer from our brake controller. It's checking to make sure we've got a good connection. In the event that we we're to have a disconnection, you can see NC is going to appear here on our screen.

The small LED that's going to be here between the area where the numbers are, that's going indicate that we've got power to our controller. The clear display's also going to have a small LED here that will indicate when you have 1 of the preset boost modes selected. As you can see, it's a nice clean looking brake controller, easy to read screen here. We've got a button here for boost mode. We've got our gain adjust here and then even manual override lever here that'll allow us to manually apply the brakes on the trailer if we don't want to use the brakes in the vehicle. The Primus IQ is proportional. That means it's going to work in relation to how you're applying the brakes in your vehicle.

If we get on the brakes really hard for an emergency stop, that's the feedback that our trailer's going to receive from our brake controller. It's a really nice advantage to the time delayed systems. We don't have to wait for those to ramp up like we used to in those emergency situations. They can be a lot more handy there. The gain is fully adjustable just by turning the knob located here on the side. The gain's going to be the amount of power that's going back to your trailer. As our trailers get larger and heavier, we want to apply more gain giving us more braking effect on our trailer, whereas when they start to get lighter, we want to turn these down.

Turning these down are going to keep our wheels from locking up and maybe flat spotting the tires. The manual override lever's going to allow us to apply the brakes on our trailer. Say we're going down a grade, or something like that and we don't necessarily want to overheat the brakes in our vehicle, we can use that manual override to apply those trailer brakes for us. The boost modes are going to allow us to adjust for different size of trailers, or different weights of trailer as they compare to our vehicle. You've got boost 1, boost 2, boost 3, and then we can actually turn the boost mode off for just let's say an empty trailer. As we get a full loaded trailer, those are going to go up. That's going to set the power and intensity that our brakes initially apply in our trailer. Mounting the Primus IQ is a pretty easy thing to do. It's going to come supplied with 2 different brackets.

You can choose which one you use, or which one's going to work best for your application. We just want to keep our brake controller level, or inclined up to 70 degrees, so we've got a good range of motion there in how we can mount it. We, of course, Want to make sure it's leveled this way. We wouldn't want it tilted this way, or this way either. We want it right in line with the direction of travel. Also, if we're sitting at a prolonged stop situation, the brake controller is going to reduce the amount of braking force that's going back to the brakes, so we won't have to worry about it overheating them, or anything like that when we're just sitting in stop. The brake controller enters a power save mode when it's not in use, so it has very minimal drain on the battery. We're not going to have to worry about our brake controller draining our battery on us. To begin the installation of our brake controller, we want to look right under the steering wheel area here and just to the right of the diagnostics port. Up here on this wire loom, there should be a gray plug attached to it. You'll see it's secured with just a little bit of electrical tape there, so pull it down far enough to where you can trim it off. Our plug will come down. This has a cover on it. Little tab right here, if you push that it's going to allow you to pull that cover off. Then we can take our pigtail adapter, that part number, 22292, and plug it right in just like that. Now we've got a ready made connector that'll slide right into the back of our brake controller. Let's get that mounted now. The brake controller comes with a couple different brackets. I like the one that has, you can see, 2 holes on that side closest to the driver, and then a hole with more of an oblong hole. This is the steel bracket. For mounting our brake controller, we're going to choose this location. You can see it's got a little flat spot ledge here. We're going to mount right there. That'll allow us to maintain the degree of angle that we need using those lower holes. This is going to take the provided self-tapping screws and we should be able to screw right into that. We want to grab the brake controller, slide it up into position. We're going to have the small holes on each side that will line up with the holes in our bracket. Now we just want to pick the angle that we like it the most once we have those screws started and get them tightened down. All right. Now we'll take the other end of our pigtail connector there and just slide it into the back of the brake controller. You can see it's going to come on in. See, showing us no connection made with our trailer there. The rest of our wiring here we'll just tuck up. There's going to be a wire loom right up here behind it. I'm going to zip tie that right off there. It will be up and out of the way, but still easy to get to if we ever need to. To test out our brake controller, we've got our tester plugged in. You could also use a multi meter. You just want to check for the voltage coming out of our brake wire pin. As you can see here, we're getting nice, strong signal. It should be perfect when it comes to braking our trailer. With the controller working as it should, that's going to complete our installation of the Tekonsha Primus IQ, part number TK 90160, on our 2012 Ford F-150.

If your truck had the OEM brake controller installed in it and you disable it to install an aftermarket controller, a warning will appear in the message center in the instrument cluster on the dash. This won't prevent the controller from operating. If the message bothers you, you can have the dealer disable it. Other than that, you won't need to see the dealer to install a brake controller. 47715
