How to Install a Trailer Brake Controller on a 2015 Nissan Titan


Speaker 1: Today on our 2015 Nissan Titan 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 axles. Part number TK90160 and to help us in our installation we're going to be using the Tekonsha plugin wiring adapter for electric brake controllers for Nissan and Infinity, Part number 3050-P. If you're looking for a proportional brake controller that has a lot of nice features, but isn't overly confusing to operate our Primus IQ is going to be a great option. It's going to give us that proportional braking and simple slide know to adjust the power. With the boost setting it's going to make it extremely easy to use.It is a proportional brake controller which means it's going to apply the brakes to our trailer at the same time and intensity that we apply the brakes on our truck. Our Primus IQ is going to have an automatic level adjuster in there and so once we have it mounted and it's within the range specified, we're not going to have to do anything else besides set our power output.

Whenever comparing our Primus IQ to other proportional brake controllers, it's going to be about mid-level. It's going to have some features that others aren't like the automatic leveling and it's going to have a display letting us know the voltage that's going to be going onto our trailer.Our Primus IQ is designed to work with trailers from one to three axles that have electric brakes only. Now like most brake controllers we're going to be able to adjust our power output by this knob over here on the left, able to go down or up as we need. We're going to have a manual adjustment slide right here in case our trailer is ever to get squirrelly, starts swaying back and forth or any time we need to apply the brakes to the trailer, but not our truck. Now our Primus IQ also has the boost feature.

We push this button on top. We can cycle through. It's going to have three different settings.The boost feature is going to apply the brakes more aggressively and more intensely starting out and ramping up and getting to the maximum power output quicker, so the higher the boost setting we have the more aggressive the brakes are going to be. Now when we have the boost setting off we'll notice that there's not going to be a dot next to the C, but as soon as we turn it on, even on level one, there's going to be an additional dot, so a quick glance down we can see whether the boost is on or off.Another nice feature is that our Primus IQ is going to be proportional in reverse, so if you've ever backed up a trailer and you go to hit the brake and they lock up on your trailer, that's not going to happen, because it is going to give us that truly proportional braking even when parking our trailer. Another nice thing is it is going to accommodate large hills.

The internal inertia sensor isn't going to go crazy or think that we're slowing down, because we're going up a steep hill. It's going to accommodate that and still give us the proportional braking.Now that we've seen our Primus IQ and gone over some of the features, let's show you how to get it installed. To begin our installation we're going to find the factory plug and that's going to be behind our dash over here on the left hand side by our emergency brake pedal. We're going to remove the two screws at the very bottom on either side. With those screws removed we're going to just gently start pulling our dash panel away, so we can rest it down on the floor.

Now there is going to be some electrical connectors, but we can go ahead and leave those attached and if we look in this general area just to the left of the steering wheel, we're going to have a lot of different plugs in here and our connector is actually going to be labeled electric brake connector.We're just going to cut the piece of tape that's holding the connector in place so we can get access to it. We're going to match up our connector, plug it in. Make sure it locked into place. Then we're going to take the other end of our connector and we're going to route it behind the dash until we can come out over towards the center of our vehicle. Now everything is tucked behind the dash and we have plenty of room to mount our controller over in this general area. We can go ahead and put our dash piece back in place. I'm just going to line up the tabs. You can just push it back in.We can replace the screws, so we can take the bracket that's included in our kit, we're going to line it up and take the included hardware and screw it right into the dash. I do want to mention you want to be careful when you're doing that. You want to check and make sure there's nothing behind there. You don't want to cause any damage to any wires or anything else. I'm using a 1/4" nut driver to put in the screw. Now one thing I do want to mention is you want to make sure that the bracket you put on is as level as you can get it. I'm going to just go ahead and drill into the plastic. We're going to just have this one loosely on there, just snug enough to hold it from moving.Double check that it's nice and level. Then we can mount our other screw, so we can take our brake controller and we're going to slide it in between the two tabs on our bracket. We're going to line up the holes. When you take the provided screw and for right now we're just going to get them started in by hand just so that we can get the brake controller supported, so it's not moving around too much. Then we can tighten up the screws. You don't want to over tighten them, you just want to snug them up to where our brake controller is not going to move once you have the angle set you want.We're going to have two screws on each side and we'll snug up all four of them. With our brake controller mounted we can take our pigtail and with that tab on the top we can reach to the back of our brake controller and plug it in. You can see that the light comes on letting us know that it's working properly. Now all we have left to do is tie up our wires underneath the dash using a couple zip ties. Now you can see that there's a C. That means that our trailer is connected and if I we're to unhook it, it's going to have an NC for not connected. A quick glance down at our controller will let us know if we're connected or if there's an issue.For demonstration purposes we have a tester hooked up so you can see the sweeping motion, the gauge is going, applying the voltage which will be applying to the brakes. That'll finish up your look at the Tekonsha Primus IQ Trailer Brake Controller for one to three axles, Part Number TK 90160 on our 2015 Nissan Titan.

This installation was for a 2015 Nissan Titan using a factory connector # 3050-P that installs directly into the port on the Titan and then connects to the brake controller. So for this brake controller there was no splicing into the vehicle wiring. For your vehicle it is difficult to say what the red wire with a blue stripe is on it as it always best to test for the function of vehicle wiring vs. depending on wiring color and coding, because it is not always consistent. If you are installing a brake controller from scratch and not using a vehicle specific wiring harness, the wiring configuration for the brake controller is the blue wire is the brake output to the vehicle 7-way, the black wire is 12V power into the brake controller and if hardwired needs to have a circuit breaker installed in-line between the battery and the brake controller. The red wire on the brake controller connects to the vehicle stop light switch and may need to be spliced in, and the white wire is a ground for the brake controller. I have included a brake controller wiring help article that explains the wiring configurations. For the trailer side of things is it not uncommon for the running light circuit (usually the brown wire) to be in a wishbone configuration from the plug depending on how the trailer is wired, a that wire activated the trailer side marker lights. 44987
