How to Install a Trailer Brake Controller on a 2013 Dodge Durango


Today in our 2013 Dodge Durango, we're going to take a look at and then show you how to install the CURT Tri Flex. This is a proportional trailer brake controller good for one up to four axles, part number is C51140. We're also going to be using the CURT Dual Plug-In Custom Wiring Adapter. This is part number C51446. The CURT Tri Flex is a proportional breaking controller, so that means when we hit our breaks, if it's a real fast sudden stop, the accelerometer 00:33 inside, that's going to apply our brakes very hard and very suddenly on our trailer for us to help us to accommodate. If we're going through traffic in the every day slowing down a little bit, the speed not slowing down, a gentle press on our brakes here are only going to activate that controller or will activate that controller at a slower, more smooth, and more comfortable rate. It's fully adjustable here on the top for our output. We can go all the way up to 9.9 and all the way down to 0.6 for our output going to our rear trailer.

This is going to self set up, self adjusting. So we don't have to worry about going through any of the set up processes. As we apply the manual override here, this is going to send power to the rear as well. We're not going to see it here because we're not moving. We're not going down the road, so our accelerometer tells us we don't need to send anything to the back.

It says you don't need to stop anything, quit hitting the button. When we are moving, when we are going down the road we can bring this over. It will incrementally go up the more we push, the more braking power we'll have to our trailer in the rear. The little red LED light that you can see, that's going to indicate that we don't have a trailer connected, or there's a fault in the trailer that we do have connected. Once we either fix that fault or plug in that trailer, that light is going to go away. Now, we've got a Cc-er that we're connected. This is the calibrating.

It's going to go through, get its set up ready. We've got our first LED here, that's going to indicate that we've got power to our controller. The second LED is going to indicate that we do have a trailer hooked up. You can see we can flex this up or we can apply some braking pressure to the back, but its not going to go to our max because we're not moving. The accelerometer says we don't need to stop anything so it's not going to. Right here we've got the plug that we're going to use to plug our pig tail in. It's got a little push tab thing there in the front that's holding it, so we're going to pop that down.

With that pushed down our plug is going to slide right off the front there. We'll pull it down there so you can get a good look at it. For our bracket, we need to find a good solid mounting location. We can go right here under the lip of the dash, there's a nice spot right there that I'm probably going to use. We're not limited too much anywhere. Wherever we want to go here, we'd be able to put it in. I'd use caution getting to far over here. You might run in to where you start hitting it with your knee on your way out. Now we're going to take the two pointed tips, self tapping screws. We'll go right through the bracket and up into the dash of our car. Now we can bring in our break controller. We'll plug it right into the harness that we just installed. Make sure it's connected. We'll bring this right up into position. We going to take the small machine head screws. We'll go into the side of the break controller. We'll have two on each side. One is going to be for our front mounting location, or our front hole location. Thread those into the rear, and as you can see that is going to give us plenty of adjustment room there. This is a proportional system so there is going to be a limit to how much angle we can have. Now with those started, let's get them tightened down. Adjust that just slightly so we can get to our gain 04:38 knob there. Now let's get that pig tail tucked up and out of the way. What we'll do is use part of the steering shaft here that doesn't move or spin while we're driving. That will give us a good, solid location to mount to. We'll just bring a zip tie around that steering stub 00:04:54. Bring our pig tail up, and then cinch that down. We can then take our side cutters, get them right up there and trim off our excess. If we've got too much slack in our pig tail, there's a nice hole right over here we can tuck it up and then it will be out of the way for us. With everything working as it should, that's going to complete today's installation of the CURT Tri flex Trailer Brake Controller, part number C51140. We also used the CURT custom dual plug in wiring adapter, part number C51446. All on our 2013 Dodge Durango. .
