How to Install the etrailer Universal Kit for a Trailer Brake Controller on a 2020 Hyundai Palisade


Connor: Hey everybody. This is Connor, here at etrailer.com. Today, we're going to be taking a look at the Universal Trailer Brake Control Kit here for our 2020 Hyundai Palisade. So this kit here, it's going to be an excellent option for any vehicle in order to convert the 4-Way to a 7-Way trailer connector. Now, if you're wondering why you may need a 7-Way trailer connector, the reason for this is, most of your larger trailers, or even some of the medium and smaller ones are going to have a 7-Way trailer connector, because they have electric brakes. Therefore, we need an extra circuit, aside from just the standard 4 pin in order to activate these electric brakes.

This kit in particular, is going to pair perfectly with any wired brake controller. So our CURT Spectrum brake controller here, it's going to be an excellent option for our vehicle.The main reason I feel this is, is because it's going to have a super, super clean installation. As we can see here, the only thing we're going to have mounted on our dash is the actual control knob, which will have these nice illuminating lights that you can change the colors in the settings. So it's going to offer a very clean factory finish if you will. We've actually went ahead and mounted it here on our fuse panel cover.

And the reason for this is, if we do decide to remove the brake controller, we could replace this panel and have a complete factory interior dash. We don't have to worry about any remaining holes in our dash here. So the Spectrum here is known as a proportional brake controller. And essentially what this means is, it's going to activate the brakes on our trailer in relation to the breaking in our tow vehicle.So that's going to give us the best stopping power for our trailer. We're not going to have a disconnect between the trailer and tow vehicle when we are breaking with our trailer.

So in regards to installation, this is definitely going to be something you can install at home by yourself. Now, depending on what vehicle you're installing it on, our Palisade here didn't come with any trailer brake wiring provisions. So we had to go ahead and run those, but it's not much of a chore at all. So now that we've gone over some of the benefits and features, let's jump right into installation and show you how it's done. So the first step of our installation here, we need to find a place to mount our 7-Pole mounting bracket.

Now, we need this to be at the rear of the vehicle and the more accessible it is, the better off we're going to be.So depending on what hitch you have, I believe most of them for this vehicle are all going to be hidden, which means we're not going to have a cross tube here to be able to just clamp our no-drill 7-Pole mounting bracket onto. So what we need to do is, I've already went ahead and bent this up, but we're going to be using a long 7-Way no-drill mounting bracket here that we sell at etrailer.com. We're going to be using this, and all we did here, we just made a slight 90 degree bend. Normally that's flat out, so we just went ahead and bent this a little bit, because I'll show you what we're going to do.We're going to go ahead and take this curved edges, we're going to slide that up behind the trailer hitch in front of the spare tire, and then once we use our band clamp, it's going to sit about right, like so. So then we're going to be able to attach our 7-Way mounting bracket to this. As you can see, that's going to be the perfect location in order to be able to plug in our trailer each time. So now that we have our no-drill mounting bracket installed, we can go ahead and attach the metal 7-Way that came with our kit here.Now we can go ahead and take our 7-Way here. We're going to feed these two ends through the center of our trailer connector like so, and then we can go ahead and mount this up using the bolts and nuts that come our kit here. So now we can take our 4-Way here, just go ahead and slide it in from the grooves in the connector, a little slot we have in our 7-Way. So, now we can go ahead and make our connection here with our 4-Pole. We just installed ours, so we're going to go ahead and make these two together now. Now, once we have our 4-Ways attached, what I'm going to be doing is, I'm just going to take some electrical tape here, I'm going to seal these both up. Number one, I don't want to have to worry about them coming apart, and number two, I can ensure that we're not going to get any water in there which will cause corrosion issues.So, now we're going to take our white ground wire here from our 7-Way, we're going to go ahead and find a good place to ground this. And due to where we've mounted our trailer connector, we're just barely going to be able to reach the edge of this metal here. So, that's where we're going to connect it. So now that we have our ground wire attached, that's going to leave us the three wires here.We're going to have our blue, which is going to be for the break output. We're going to have our yellow, which is for reverse. We're just going to take this one off, the majority of applications aren't going to require reverse lights, so most people are just going to tape this off as well. And then we have the black wire here, which is for the battery charge line circuit. Now, in our kit here, we're going to have this bonded duplex wire here. It's a black and white wire here with a gray jacket. What we're going to do is we're going to connect each of these to the blue and black wires, respectively. We're going to match blue to white, and then black to black to keep everything simple.Now that we have all of our connections made, what we're going to do next is, we're going to go ahead and use some electrical tape. We're going to tape up all these connections. We're also going to use some zip ties to secure it to some existing wiring harnesses up there. That way we don't have to worry about it dragging the rope. So now that we have all of our wires secure, we're going to go ahead and take our duplex wire here, we're going to run this up to the front of the vehicle. So we're going to go ahead and do that now, but the route we need to take is, we need to make sure that we're free of any of the exhaust or any of the suspension here.So now that we have the duplex wire ran, we can go ahead and show you the path we took. Just came straight back through a trailer connector, tied it to some existing wiring harnesses here, the bracket here we used a zip tie. Now he came up and over this rear sub frame here, and you should see the duplex wire exit here behind the gas tank. And then the rest of the installation and the rest of the routing is real, real simple, because we just followed the brake lines up to the front of the vehicle. We didn't have to use a couple, remove a couple of 10 millimeter bolts here, so we can bring this down and reveal our brake lines. As we said, the rest of it's pretty smooth sailing, because we're just tying it to the brake lines.And you can see here, we have the end of our wire here, which is where we're going to leave it. The white wire needs to go up inside the vehicle, our black wire needs to go into the engine bay to the battery. So what we did is, we just went ahead and split some of that sheeting off the wire, we can split them up. And if we lower this panel a bit here, we're going to have a grommet directly above here. So what we did is, we just went ahead and made a slit with a razor blade in that grommet, and then we fed our white wire once we separated it, up through that grommet and into the vehicle. We had to remove a couple of panels and pull forward up a little bit, but it wasn't too hard to get our white wire out here.So we're going to throw this back in the vehicle, because it's going to be connected to the brake controller earlier, because if you remember, this is going to be our brake output wire. So the next thing we're going to do now is, we're going to go in the engine bay of the vehicle, we're going to fish down a pull wire, so that we can pull up our black wire that's underneath the vehicle now. Now we would have had in taped our black wire to the pull wire once we pushed it through. So now all that's left to do, just pull it up to the engine bay, just like that. And now what we're going to do is, we're going to have to route this over here to the location of our battery, because this is going to be eventually run to the positive terminal on our battery, which is going to be over here.However, before we attach to our battery, we need to install a circuit breaker in line. So I think the next thing we're going to do is, we're going to find a good place to mount our circuit breaker. Keep in mind, we're going to be using two circuit breakers, so we want enough room for two of them to mount. So if we take a look directly in front of our fuse box here, we're going to find a good location to mount both of our circuit breakers. We have a nice piece of flat bare metal here, so that's going to do a great job of holding the circuit breakers.We have a 40 Amp one, which is going to go to the trailer battery charge line, and then as we stated, we're going to have to install another one, either a 20 or a 30 Amp that goes to the brake controller. So let's go ahead and get these bolts installed now. So we went go ahead and just routed our black wire here behind our fuse box so we can get it to come out where our circuit breakers are. So what we can do is, we can go ahead and trim the excess that we have here.Now, what we can do is, we can go ahead and attach one of our ring terminals to the end of our wire here. And then that's going to go to the silver post on our circuit breaker. The copper post will then go to the battery. So now we're going to take part of the excess wire we just trimmed off there, and on the one end, we are going to attach another ring terminal, so it could go to the copper end of the circuit breaker there, then the other end, we will attach another ring terminal too, so we can connect it to our battery.Now we can go ahead and find a path to route this to the battery. I'm just going to crimp on a ring terminal here, and there's a 10 millimeter nut on top of the battery that we can remove to attach our ring terminal here. Keep in mind, in order to reclose this cover here, we may need to cut a small notch out here for our wire. But we're not going to need to do that yet because we still have another power wire to run from the battery inside the vehicle to the brake controller. So now that we have the connection made here for our battery charge line, we're going to go ahead and connect the brake controller power. We're going to start on the battery side with the copper terminal here. So I'm just going to take some extra wire that we have and the same process we've been doing this far, just crimping on a ring terminal.We're going to route that over like so, and connect it to the positive post on the battery, just like we did for the other one. So now we're going to take, again, we have some extra black wire left over from our strand here, we're going to attach the auxiliary side here of the circuit breaker that goes to our brake controller. So this one's actually going to go inside the cab. What we're going to do is, we're going to make our connection here, and then we're going to feed it over here. And we're going to trace it back down through the engine bay, through our black wire here. And then we can go back into the vehicle using the same grommet we used earlier for the white wire, which is to the break output. Let's go ahead and do that now. We have our black wire here, which is going to be the power wire for our brake controller. We have the white wire here, which is going to be the brake output for our brake controller. Now we can go ahead and make our connections for our pigtail harness.We only have four wires here. They're all going to be labeled for you. The white is going to be for the ground, the red is going to be for our stoplight switch connection, the black is obviously for power, and then the blue is for our brake controller. But now that we have all of our wires set up, we can go ahead and begin to make our connections.So I am going to feed the wires down through the fuse panel cover here, because that's where I think we're going to be mounting our controller. So I'm going to go ahead and make these connections now. The white wire, I know, that's coming from the back of the vehicle, that is going to be for the brake output. So that's going to go to the blue wire we have here. Then we have our other white wire here, we actually just ran that to a ground inside the vehicle. So this is going to be our actual ground, it's going to go to the white wire on our harness. We have our black wire here, which is for power, that'll match up with the black wire from our harness.And then the last one we need to obtain is the stoplight switch circuit, which is going to tell the brake controller when we're pressing the brakes. So it's going to be a little bit hard to get to. You're definitely not going to be able to see it, but up underneath, if we just follow the brake arm, we're going to see the bundle of wires, a connector that comes from the brake pedal. There's going to be about six wires in there. We're going to be looking for the green wire with the black stripe. That is going to be the cold side of the brake pedal. So what we want to do is, we want to take some extra loose wire here, we're just using blue, and we're going to attach our Quick Splice connector here. One end of the wire slides up there, then the other end of the wire is going to wrap around that green wire with a black stripe. That way, we can get our stoplight switch signal. Now, finally, we have our red wire for the stoplight switch that's going to go to the blue wire that we've run earlier.So once we have our pigtail installed, the next thing we're going to do is, we need to find a suitable place to mount our control knob. Now, I have a great idea here for this vehicle, what we're going to do is, we're actually going to remove the lid to our fuse panel cover, the reason we're going to do it on the fuse panel cover is, if you ever decide to remove the brake controller, we don't have to worry about having a whole inner dash. So you could easily just replace this piece here and be completely back to factory. So in order to install this, we're going to want to line up our little Dial holder here, we're going to center that in the panel, and then we are going to make two marks here that we're then going to drill out. So now we're going to take a 5/16 inch Drill Bit, we're going to drill out those two holes we marked.So now we're going to take our weld nut here, we're going to press that in through the back, and we can take our screw and tighten that down to secure it place. And then we're going to take the wires, and we're going to see them through our center hole here, and we should be able to press our control knob into place, and we should hear it click when it is locked into place.And now that we have our control knob mounted, we want to be careful for this next step, but we can go ahead and attach the wires into our connector here using the instructions as our diagram. Now, we went ahead and took our control knob here. We went ahead and attached it to our module box, and then we took the pigtail that we wired up early and attached it to the other side. Now we just need to go ahead and find a place to mount the controller along with the rest of our wiring, so that we can put our panel back on. You have a couple of different options for this, we could use a double-sided tape or we could use some zip ties and tie it to some existing wiring harnesses. So now, this time we can go ahead and reinstall our Trim panel we removed earlier. So we can go ahead and plug our trailer in now and test our brake controller out.So once we get the trailer connector plugged in, we should see the green lights, which means it's initializing. Then we can go through our different settings here. If we hold it for our manual override, you can also adjust the level of manual override by turning our control knob. So now, let's go ahead and activate all our signals. First, we can already see we have the running lights on on both connectors. Let's test the left turn, the right turn, and then finally our brake. And that's going to do it for our look in installation of the Universal Trailer Brake Control Kit here for our 2020 Hyundai Palisade..
