Gain and Load Adjustment

Curt Discovery NEXT

Gain is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. You want to go as high as you can without the trailer brakes locking up. Use the orange rocker switch to adjust the gain on a scale of 0.5 to 9.9 in increments of 0.5.


Once you have the gain set, you can fine-tune your braking by adjusting the load control on a scale of 1 to 9 using the black rocker switch. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, decrease the setting.


LED Display

The LED display on the Discovery is large and easy to read at a glance. You can adjust the brightness or trigger night mode so it won't glare obnoxiously on your dash. It also will give you clear error messages you can use to troubleshoot.

Installation

Because inertia plays no role in the functioning of this controller, your mounting options are limitless, so long as you can still easily access the manual override. The included bracket is designed to mount the brake controller flush to the dash so it takes up almost no space at all.


The included custom-fit adapter plugs into the port on your vehicle's built-in brake control wiring harness, which you'll find underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. Once you're plugged into your factory port, just plug the other end of the adapter into the Discovery. Because there are no wires to connect, installation is not permanent. You can unplug and remove the controller at any time to transfer it to another vehicle or securely stow it away.


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 control installation kit (ETBC7 - sold separately).


What is Time-Delayed Braking?

what is time-delayed braking

Time-delayed braking means that when you apply the brakes in your vehicle, the controller activates the trailer brakes at a pre-set intensity and rate. Both the amount of braking power (gain) and rate of application (load) can be adjusted to suit your preference, the road conditions, the type of trailer, and the weight of your load. To determine which levels are best for your application, test your towing setup and choose what feels right.

Video Transcript for Curt Discovery NEXT Trailer Brake Controller w/ Custom Harness: The Breakdown

Hi, everyone, Aidan here with etrailer. Today, we're gonna be taking a look at the Curt Discovery NEXT Brake Controller. This is gonna be a time-delayed brake controller. Let's check it out. When it comes to brake controllers, there's gonna be two options you're probably looking at, time-delayed and proportional. Proportional is gonna be the nicer of the two where if you lightly press your brakes, the brakes in your trailer are also going to be lightly applied.

If you slam on the brakes, the brakes in your trailer are also going to match that proportionally. With a time-delayed brake controller, it's gonna be applied at the same rate every time, so you don't get that fine adjustment. You can still adjust the settings, but it's gonna be the same every time. So if we're rolling up to a stop sign, coming to a very slow and predictable stop, and our gain and sensitivity are set kinda high, it's gonna be applying the brakes pretty hard. Same for if we have those set kind of low and we slam on our brakes on the highway, because someone in front of us stopped, the brakes aren't gonna be applied in a similar fashion.

There is the manual override you can always pinch to apply, but that's just something to know with a time-delayed system like this. Let's talk about those controls. The manual override is a pinch style where I'm pressing the button with my thumb. It's pretty easy to reach from the driver's seat where I've got it all set up. So whenever I'm driving, I feel like if I needed to suddenly reach down and get it, I can find that pretty easily every time, and index my thumb well enough to get a good press.

So good to know for emergency situations where you might need that. Now, there's gonna be two sets of controls here for the gain and the load. The orange buttons are going to adjust our gain or our brake power. You can go anywhere from 0.5 up to 9.9, and this is going to signify the different power levels. So 0.5 is the weakest, and as I go up, it's going to get more and more powerful.

So if I have a heavier trailer that needs more stopping power, I'd set it higher. The next one is going to be our load. This is basically how quickly the brakes are applied, so that can go from 1 to 9. At 1, it's going to be the lowest, and at 9, it's going to be the fastest or the quickest application. So basically, ramping from zero to fully applied where we have that gain set. So for demonstration, I'm just going to put the gain all the way up to max, and I'm gonna hit the brakes. And you'll see, slowly, it'll climb up to where we set it. And if I turn that load down all the way to 1, it's going to climb much slower to that designated power level. So you can fine tune this to your own trailer application, and depending on how heavy of a trailer you have and how good the brakes are, that will determine what you want those set at. But generally, that gain is going to be for the weight of the the trailer, and you can kinda determine the load from there. Now, to give a visual indicator of that gain, we've got our vehicle hooked up to a trailer simulator box. I've got the gain set to the absolute lowest it goes, so that's gonna be the lowest brake power, and you can see where the voltage is reading right now. If I turn the gain up to 5, that's gonna be right in the middle, you'll see that voltage will climb up higher. And then if I turn it up to the max, 9.9, you'll see that climb up even higher. So this is just to give you some visual indication of that different power level of the braking. This is designed to work with trailers up to four axles and will work with PWM, ABS, cruise controller, and electric-over-hydraulic brakes. So keep that in mind as you're picking this out if it's gonna work with your trailer. Up to four axles, I'd say for the most part, you're gonna be totally fine. If you don't need one that can go up to four axles and you like this style, Curt does make a similar version that's up to three axles. So that's something to keep in mind too if you don't need this much. Now, the big advantage to something like this, and something you probably noticed if you're familiar with brake controllers already, is going to be the size. It's a lot smaller and a lot more shallow than the brake controller we pulled out of this 4Runner today. And that's great, because even though it's mounted externally, it's not going to be in the way of your knees as you're getting in and out of the vehicle. And as I'm in a normal driving position, I've got plenty of distance between it and my leg. I don't feel like I'm gonna be hitting it all the time, 'cause it doesn't stick out very far. That's thanks to the very low profile bracket. We've got it mounted up with the included double-sided adhesive, but you can also use the included self-tapping screws. Just know that they're pretty long, and you're gonna have to have clearance behind there. But this will just click into place over that bracket. (bracket clicking) You can hear that snap in, and that's what holds it in. One thing to note is that because it's not inertia based, you can mount this really wherever it fits best, so it doesn't necessarily need to be level or facing any certain direction. Now, the installation can vary depending on your vehicle. I'd say check for what your vehicle has in terms of pigtail adapters. That's what we we're able to do with this option from Curt. We offer this pigtail adapter on our site here at etrailer, and that allows us to just plug directly into the vehicle's prep package for this. So just check to see if your vehicle can do that, because that's definitely going to be the easiest option as far as installation goes, 'cause it just plugs right in and all you have to worry about is mounting up that bracket, and then tucking up that wire loom from the adapter. Something else to note is that that LED readout does have a number of different functions. You can adjust the brightness, there's a day and night mode, but it's also gonna give us readouts for different errors. So if something's maybe not fully connected or something, it will tell us here. Your instructions give you a full list of all the different errors that can occur and short descriptions of what they are. But because its screen gives full text readouts, it's pretty easy to tell what's going on based on what it's showing. Like for example, when we first hooked this up to our simulator box, we didn't have the 7-way plugged in all the way, and it told us it wasn't connected. So we went back there, pushed the plug in the rest of the way, and then it worked properly. So that's going to help with just troubleshooting anything that may be occurring in your setup. For me, I think this is a nice middle ground between having the controls, easy to access, and having that LED readout, so you can see those errors and the power, and just have a little bit more control over it while still staying out of the way and being flushed to the dash. But that was just our look at the Curt Discovery NEXT Brake Controller. Thanks for watching.

Just finished the install. It was nice to be assured that I had everything I needed to finish the job before I got started. Honda didn't make it easy.

This part is listed to fit a 2019 Honda Pilot. I needed one for a 2019 Honda Passport;(basically the same vehicle); however since the Passports just came out in about February no one could tell me if it would work on the Passport. So I took a gamble and ordered this wire. Well I can confirm that this part does work on the 2019 Honda Passport. The hardest part was reaching the plug under the dash and getting this wire to plug into it, all without any room and only being able to get one hand up under dash. Wire made hooking up brake controller a lot easier than direct wiring.



by:

Tested . Work fine and advertised



by:

Everything about the buying experience has been great! I was impressed with the email communication and the actual phone call to let me know that my ordered had been shipped out. I will be using the etrailer.com website again to make purchases for my trailer and camper accessories! Thanks!

  • Troubleshooting a Curt Discovery Brake Controller That Has Jerky Brakes
    Wes, it could be possible that your brakes are jerky after they are warm because you adjusted them while they were cold. So what you can do recommended to warm the brakes by applying the manual lever for a bit while driving at slow speed; once they're warmed you can adjust them properly. Another possibility is that the delay is set too long on the controller. I'd suggest trying to set the delay to activate sooner and see if that fixes it. If all that does not work, then there could...

  • Where to Connect the Adapter to Install a Curt Brake Controller in a 2017 Nissan Pathfinder
    To install a Curt Brake Controller, like the Discovery # C84VV, on your 2017 Nissan Pathfinder you will simply need to plug the Custom Wiring Adapter # C51382 under your dash like you mentioned. I am attaching a video where one of our install guys installed a Tekonsha Prodigy P2 # 90885 in a 2013 Pathfinder using the Tekonsha Wiring Adapter # 3050-P. If you skip to the 2:45 mark you can see where he plugs in the adapter for the Prodigy P2. Your Curt adapter will plug into the same place.

    The Curt Spectrum Trailer Brake Controller # C51170 has a wiring harness that is 48 inches long between the knob and the concealed box. I reached out to the manufacturer to confirm that measurement for you. If you have the factory 7-way on your 2016 Honda Pilot then you will simply use the Custom wiring harness # C51392 which has a 24 inch length to connect your controller to your factory wiring harness. If you do not have the factory 7-way, then you will want the universal wiring harness...

  • Which Curt Echo is Better? The Inline or Under Dash
    Hey Jon, so in theory the inline Echo Mobile part # C51180 and the under dash part # C27JR should perform the same but we have found that the under dash version works a lot better so it would be the way to go. Overall performance and connectivity just is more consistent. It's also not easy for a thief to potentially steal like the C51180. Which to install it in your 2023 Honda Ridgeline all you would need is the part # C51392 and you'd be set.

  • Can I Use the Curt Discovery Brake Controller in a 2021 Honda Pilot
    Yes. You could use the Curt Discovery # C84VV on your 2021 Honda Pilot with the plug and play adapter # C51392 to allow for an easier installation that won't require cutting into any wiring. However, the Discovery is a time delayed brake controller, which means that it applied the brakes with the same intensity and with a slight delay in response to the tow vehicle's brakes being pressed. I do typically recommend going with a proportional brake controller, which uses gyroscopes and sensors...

    The 2019 Honda Ridgeline is pre-wired to attach a 7-Way plug that powers trailer brakes but not all Honda Ridgelines have the wiring harness for a plug and play brake controller adapter.

It also comes with the relays needed to activate the tow package on the Ridgeline so power the circuit needed on the 7-way needed...
