How to Install a Trailer Brake Controller on a 2016 Ford F-150


Today on our 2016 Ford F-150, we're going to take a look at and show you how to install the Tekonsha Primus IQ Trailer Brake Controller. This proportional brake controller works for one up to three axles. Part number on it is TK90160. We're also going to be using the Tekonsha Brake Controller Adapter. This part number is 22292. Here's our brake controller once we have it installed. The Primus IQ is a proportional brake controller.

This is going to operate in proportion to how much braking we're doing in our truck. The accelerometer that's located inside senses when we hit the brakes, whether it's in a normal operation or in a panic situation, and applies the brakes accordingly to our trailer. The benefit of to that is that we don't have to wait on our time delayed systems. Those are going to start at the bottom and then slowly ramp up. This one can instantly send the appropriate amount of braking power to the rear of the vehicle for us. Another great thing about the Primus IQ is going to be the safe guards that we've got built in.

It draws very low power when not in use from our vehicle's batteries, so we don't have to worry about battery run down. It's also going to safe-guard the brakes on our trailer. For prolonged stops at stop lights or stop signs, it's slowly going to decrease the amount of power being sent to the brakes on the trailer so they don't overheat. Under normal operation as we head down the road we'll see the C indicated on our brake controller. If for some reason we we're to have a connection failure, it will then start immediately flashing NC, NC. That's going to indicate to us that we've got no connection.

Once we're re-connected the C is going to come right back on indicating to us that we've got a good connection. Here's our manual over ride lever. As you can see that's going to allow us to go right up to whatever our maximum setting is. Whatever we've set the brake controller as far as the gain goes, as we hit that it's going to take it right up to that maximum that we've got set. Even in the case of an emergency when we're reaching down here, maybe in a little bit quicker situation or maybe more in a panic situation, we're not going to overload the brakes on the trailer and risk locking them up. Here you can see we've got a boost mode, B1, 2, and 3. It's indicated by an LED that's going to sit down there in the corner.

Right now it's off so there's no LED. If we switch it into boost 1, eventually the B1's going to go away but that LED's going to be on there. That's going to indicate to us that we are in a boost mode. That allows us to fine tune our brake controller. That's going to set how quickly and how aggressively those brakes are applied. That's used mainly when our trailer begins to become very heavy in relation to the vehicle. We need to boost that up a little bit just to help to control our braking. Now the gain that we're going to set, this is going to depend on driving styles, on trailer load, on road conditions. Every time, even with the same size trailer, we may have to adjust this a little bit. Really easy to do as you can see with that thumb knob right there. We just rotate that forward or back and adjust it. As far as mounting the IQ goes, we've got everywhere from zero degrees, which would be perfectly level, all the way up to about seventy degrees as long as we're keeping it inline with our direction of travel. We want it to be straight this way. That allows the accelerometer inside to be at it's most effective. The first thing we need to do is get our shroud out of the way that's going to be underneath this side panel which we're going to remove. Now this is going to have a bolt located right up here on the side. We're going to have one on each side. That's what it's going to look like. Take the one out here on the drivers' side. We'll do the same thing on our passengers' side. Now on our passengers' side we want to reach up right at the very tip of this shroud, just about there, and if we pull out on it you see there's a little clip that we separate. That'll allow this side to come free. Should have another clip there, and then we'll get the last one right over on that corner and pull it out. All right now we'll set that aside. We'll put it back in once we get our brake controller in. Now we come right down here to the bottom and we want to just carefully work this out and separate our clips. Now we've got our little cubby hole that's right behind that rectangular shaped hole. It should be plugged right into the back of that. You see it right there What we're going to do is just allow that to come down an we'll pull it right over here. You can see we can pull it out right here to where it'll be easy to connect to. Now we'll get our dashboard reassembled here. Cubby hole's going to go back in. The key with getting this put back together is just making sure that our clips line up. Now let's put our shroud back in place. Now we're ready to grab our pigtail, line it up and slide it in. You want to hear that audible click and then you'll be able to push and pull on it without it coming apart. That way we know we'll have a good connection. Next we need to just set that aside for now. Let's get our bracket mounted. We want the bean shaped hole to be rear-ward. Then we can use our provided screws and go right up into the bottom of our dash. Of course we checked behind there before to make sure we don't have any wires or anything that run through there. You can see, nice and secure. Now we'll take our pigtail. As you can see slides right into the back of the primus there. To mount it we'll just bring it up into our bracket and line up our holes. I always like to mount them as high as possible. I don't necessarily care too much about pivoting on this one. We'll use our provided screws that are going to come with it. Those will go right through our bracket into the holes already in the side of the brake controller. As you can see, nice and sturdy. Now once we've confirmed that it's working for us, we've tested it out, all we have to do is take our excess pigtail, zip tie it just kind of tie it up out of the way there so we don't have to worry about it coming down and getting hung up on our foot. Now with everything working properly that's going to complete today's installation of the Tekonsha Primus IQ Trailer Brake Controller. This proportional brake controller works for one up to three axles. Part number on it is TK90160. On our 2016 Ford F-150.
