How to Install a Trailer Brake Controller on a 2008 Nissan Titan


Speaker 1: Today on this 2008 Nissan Titan, we'll be having a look at and showing you hot to install the Tekonsha Primus IQ Trailer Brake Controller, part TK90160. We will be using the Tekonsha plug and wiring adaptor for electric brake controllers, part number 3050-P.Here's what our brake controller looks like installed. What this brake controller's going to allow you to do is control your electric brakes on your trailer. Without having this, you wouldn't be able to use your trailer brakes, potentially causing an unsafe or in some states, an illegal condition. If you have trailer brakes, you want to be sure you can use 'em and this will allow you to do that. This brake controller is proportional brake controller that can control up to three axles of trailer brakes.

What a proportional controller means is that if you're slowing down gradually in your truck, so your brakes in your trailer will be applied in the same manner as your brakes in your towing vehicle. That way, you come to a smooth and safe stop. As opposed to a time delay controller where there is a delay and sometimes the stops can be jerky because the brakes aren't being applied in the same manner.When you step on the brake in your vehicle, the brakes are going to be applied on your trailer. But since we're not moving right now, that's why you're not seeing any numbers on how much force is being applied. That's because there's inertia sensor inside.

You don't want to have your brakes applied in your trailer for too long; otherwise, it could burn out the magnets in them.Now this is a basic controller. It gives you the minimum functions that you need in order to control trailer brakes, but it doesn't sacrifice quality while doing so. Over here to our right, we have our manual override switch. What this will do is it'll apply only the brakes on the trailer without the brakes in your vehicle being applied. So if you start to have a jack-knife situation, and you need to bring the trailer back in line behind you by slowing it down, just slide the lever on over, and it'll apply the brakes on the trailer.As you can see here as you start to move it further over, there's more power being applied to your trailer brakes.

The more you have it over, the harder they're going to be applied. Over here to the left, we have an adjustment wheel. What this is, is our gain adjustment knob. So if I press on our manual override here, have our knob all the way up, you can see we have max power being applied right now, as we move the knob down, we can adjust in increments all the way down to zero, which will be no braking assist. Since ours is up to about 10, we'll set ours in the middle at about five and this is a great starting point because it's right in the middle and if you need to add more brakes, you can dial it up easily or if you need less, you can dial it down easily depending on your situation, depending on how heavy your trailer is, or the type of driving terrain that you're in.Now on the top right above our LED display, we have a button and this is our boost button.

What this will allow us to do is change how fast and aggressively the brakes are being applied on our trailer. There's three different levels of settings. First one, right now we're on off. Then we have boost one, then we have boost two, boost three, and then off again. With boost level one, the brakes will be applied a little bit more aggressively and a little bit quicker. With boost two, it's higher than boost one and with boost three, it's even higher than boost level setting two.Now that's the only three adjustments points you have. You have your manual override, your boost and your gain adjustment. There's nothing else to make it overly complicated and difficult to use. This is a great brake controller that's simple and easy to operate but yet is very high quality and gives you the functions that you're looking for and that you need. Now that we've gone over some features, we'll show you how to get it installed.We find ourselves underneath the dash on the driver's side of our vehicle. We're looking for the factory brake controller port. We look right above our parking brake. There's a white plug right here. This white plug right here is our factory brake controller port. We can take our adaptor harness and we'll plug into that. This harness is keyed so it only goes one way, just push and it'll click into place, pull back and make sure it's secure.With it plugged in, we routed it over our hood release cable and handle right here and we got plenty of wire length so we can mount our brake controller on the right side of our driver's dashboard. Be right about in this area here. We just want to make sure we're not blocking our data length connector here for our OBD-II port 'cause that port will need to be used anytime the vehicle needs to be serviced for a check engine light or for emissions testing.Now before we mount our controller, we'll be sure we plug it into our harness. So we're gonna find a place, mount our controller to make sure it's not going to interfere and right like this, we should be okay and won't cause any interference for our wires to access the OBD-II port. So with it held in place right here. We'll just take this down for right now. We'll just line up this edge of our bracket right with the edge panel of the dash. It'll be about a quarter inch below this speaker output right here for your door chime.We'll use our provided quarter inch screws to mount our bracket. When we mount this, we want to make sure it's as level as possible because this will determine how level our brake controllers sits. I already determined that there was no wires behind our dash that we could potentially screw into and cause damage. With the bracket mounted, we can now mount our controller. We'll also use the provided screws for this. So we got our pivot one installed, now we'll install the one that locks our angle in place.Now we just want to make sure our controller was level this way. It doesn't matter this way as far as the level. It'll still function properly. Okay, we'll get our screw on the side started. I'll use a right angle screwdriver for this. So we're just repeating the same process that we did on the other side of the controller, getting our screws started.Now that we have these started, we'll fully tighten them so our controller won't pivot on us as we're driving. We'll secure up our loose wires underneath the dash with a couple of zip ties. We have zip ties available on our website if you'd like to purchase some.Now that we have our brake controller installed, we're gonna make sure it's working properly. So we hooked up our trailer to our truck. We have a C which shows that we're connected and there's a dot in front of the C which means everything's working properly. This means we have a valid connection. If we we're to become unplugged from our trailer, it would show NC for no connection instead. We'll mainly operate our override here to make sure our brakes are being applied and they are. So we know everything's working properly. Now that we know everything's working properly, we're ready to hit the road.That completes our look at and installation of the Tekonsha Primus IQ Trailer Brake Controller, part number TK-90160 on this 2008 Nissan Titan.
