Specs:
You can adjust the gain (also known as output) with the thumbwheel on the front of the controller. Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. A heavier trailer will need more power to achieve smooth, safe braking, while a lighter trailer will need less. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes.
The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.
Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set gain. What this means is that, 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.
If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.
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 adjust the boost, use the blue push-button on the top of the Primus IQ.
The Tekonsha Primus IQ comes with an easy-to-reach, slide-bar manual override, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just push the slide-bar to the left, towards the center of the controller. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.
The Primus IQ can mount between -90 degrees and 90 degrees vertically, but the brake controller still needs to be horizontally level and parallel with the direction of travel.
After mounting the Primus IQ unit in your cab using the included bracket, simply plug the included custom harness into your vehicle. The other end of the harness plugs into the brake controller. To remove the IQ for storage when you're not using it, just unplug the unit and slide it out of the bracket. With a replacement wiring harness (sold separately) and replacement bracket (6927 - sold separately), you can even transfer the IQ 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).
The Tekonsha Primus IQ brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, 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 Primus IQ 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.

Speaker 1: Today on our 2007 Toyota Tundra, we're going to be taking a look at and showing you how to install the Tekonsha Primus IQ trailer brake controller for one to three axle, part number TK90160. To help us get that installed, we're going to be using the Tekonsha plugin wiring adapter, part number 3040-P.This is what our brake controller looks like when it's installed. What this is going to be good for is this is going to help you apply brakes to your trailer while you're traveling, in turn saving the brakes on your truck. This is going to be a proportional brake controller which means that the braking force applied in the truck will be matched on the trailer. For instance if we have a quick braking situation and you apply the brakes in your truck, the same amount of force will be applied to the trailer brakes so that the trailer will stop itself instead of the truck having to stop both.Now how this is going to differ from a time delayed, on a time delayed brake controller, when you apply the brakes in the truck it's going to take a few seconds for the brakes to be applied in the trailer. This is just the opposite.
When the brakes are applied in your truck, the brakes are automatically applied in the trailer at the same time. This button here is going to be for our gain. This is going to allow us to adjust the amount of force being applied, or being sent to our trailer brakes. This button here on top is going to be our boost. We're going to have three settings.
It's going to be zero, go to one, boost two, and boost three. Now we're going to set this depending on our trailer load in reference to the weight of the vehicle.Boost one's going to be for a trailer, maybe a light trailer that is not loaded. You're not going to want any boost or even boost one maybe. As your trailer gets heavier, or trailer matches the weight of the truck or goes over, you're going to want to go to boost two or boost three. And what that's going to do, is that's going to adjust the aggressiveness of the braking force sent to our trailer.
This button here, or slide knob, is going to be our manual override. And what that's going to do, is whatever we have our maximum pressure set at, and the maximum force set at, this is going to allow us to apply the brakes on our trailer without applying the brakes in our truck.So if we have an emergency situation and our trailer feels like maybe it's swaying or getting off center from the truck, maybe you're going down a hill, and you want to apply those brakes on the trailer to get it back steady again, or back behind the truck so you have control of it. You would use this button right here. As far as the installation, it is going to be very simple and straightforward. You'll just need to get that adapter plug from Tekonsha.
It's going to plug directly into your factory tow package wiring underneath your dash.Now that we've gone over some of the features, let's show you how to get it installed. So to begin our installation, we're going to take the white end of our adapter plug, and we need to find the matching end. Now if you look right up here behind the emergency brake pedal, right above this panel you'll see a plug. Very easy to get to. We're just going to take our white end, plug them in together until you hear it click. The next thing we need to do, is we need to mount our ground wire. Now what I like to do is try to find an existing nut that is mounted to the body, make sure it's on metal. You look right here behind the emergency brake pedal, there's a nut.You can see our ring terminal's just a little bit too small, so what we're going to do is we're going to replace that with a bigger one. Super ring for our 10 to 12 gauge wiring. So we'll cut off this one, crimp this back, crimp it down. Give it a little tug, make sure you've got a good connection, and we'll take a half inch socket with a fairly long extension, and take that nut off. Add our ring terminal, and then replace our nut. Next I'm going to route my adapter. What I want to do is I want to find some existing wiring up inside here that I can zip tie or secure it to. I'm going to run it across. You want to make sure it's over on this side of the steering wheel.The reason you want to stay away from this side, is when you're getting in and out of the truck, you take a chance of damaging it or hitting it, knocking it off. Next I'm going to take my wire. I'm going to take some black electrical tape, and I'm going to cover up my wires just to kind of help it blend in with the brake controller itself. Just kind of make it look nice. Next we're going to mount our bracket that's going to hold our brake controller onto our dash. You see, our customer had something preexisting he had here. So what we're going to do is we're going to use the same holes. I'm going to make sure I'm going to be able to put my bracket there. It looks like we'll be able to fit it.So we're going to take the screws that comes in our kit with our brake controller and we'll fit it in place. On your brake controller you're going to have two holes on each side. On your bracket, you're going to have an elongated hole on each side, and then you're going to have another hole above it. That's where we're going to be mounting our brake controller. Your kit's going to come with a couple extra screws. So we'll line up our holes, and our brake controller will fit into place. Go ahead and put our remaining screws into place. And you can use just a regular socket on this. You can see this is a very small space to get into.Now that we've got it plugged in, you can see here on the top it's blinking NC. That's means no trailer's connected. But you can see we do have power. So next we'll test it out to make sure we're getting power to the seven pole in the back of the vehicle. Now that we have our alternative power source connected to the vehicle, you can see on the screen here that our NC changed to a C showing that we're connected. That's going to be good so that if you're traveling, and it goes from C to NC, you know you have an issue with the trailer. You need to stop and check it out. And that'll do it for a look at and installation of the Tekonsha Primus IQ proportional trailer brake controller for one to three axles, part number TK90160 on our 2007 Toyota Tundra.
