How to Install a Trailer Brake Controller on a 2012 Chevrolet Silverado


Today on our 2012 Chevrolet Silverado, we're going to be installing the Curt Venturer. This time-delayed trailer brake controller is perfect for use with 1 to 3 axles. This part number is C51110. We're also going to be using the Universal Wiring Adapter, part number C51515. A great thing about the Venturer is the sync adjustment that's available on it. This little slide bar right here on the side, we can slide this forward or we can slide it back. Sliding it back towards us is going to give us gradual braking force, so as we apply the brake you're going to see this slowly work its way over to give us maximum brake engagement.

Now if we want a faster or a quicker braking force, we'll slide that sync bar forward and with it all the way up, watch that same meter with the same force applied to the brake. It's going to build up braking power much quicker. You see there, it's almost instant that we've got full braking power as opposed to when we turn our sync down, it's going to gradually build up. As you can see, we're going to start our install by getting our wiring harness from up here. This is our brake pedal, brake pedal arm comes up, and it's going to be located just to the driver's side of that. If you can see, there's a piece of white tape right here that's going to hold that in place.

We're going to cut that tape and pull those wires down to us. Here you can see once we get that cut off, it's going to list what each of our wires are for. We'll want to hold onto that for reference. We can then pull our wires down. As you can see, we've got plenty of room to make some good connections here under our dash. Now let's bring in our universal wiring harness. This is that part number C51515.

We're going to match these up with our wires under the dash. Now we're not necessarily matching color-to-color here. We're going to use the . You remember the guide that we pulled off our factory harness and also the guide that's going to be wrapped around right here at the end of your new harness. The first thing we need to do is get our ground taken care of. That's going to be the white wire.

The ground on our truck, also a white wire. Those are going to run white-to-white. We're going to use butt connectors here to allow us to make a nice, quick but secure, connection. I'll strip the end of our white wire off there, slide it in the other end, and crimp that down, too. You always want to give it a pull, make sure it's nice and secure. Next is going to be our battery power. That's going to be the red wire with the black on our truck. It's going to be the black wire on our harness. All right. Next our blue and white wire. It's the small one here. That goes to our brake switch. That's going to be the brake signal from vehicle, so that needs to go onto our red wire. Lastly, our dark blue auxiliary, that's going to go with the blue electric brake feed to our trailer. All right. Everything is nice and secure. We'll take our extra wire, our orange wire, we're not going to be using that for our application, and we'll wind that up here. Then we'll use some black tape, wrap it all up. Wrapping it up certainly isn't required but can help clean up the look and also keep everything a little more manageable for us. A nice thing about the Curt harness there, it's got a loom on it already. We'll just run this right down to that loom. Now we're going to get our bracket mounted up here in location. We found a nice, flat spot here that's going to work fine. We're actually going to be able to reuse one of our factory screws here. We'll have an already existing hole. It really helped us to limit the amount of holes we'll be adding. We'll just slide our bracket up behind the tab there, put the screw right back in the front, and we'll draw that right down. All right. With that secure, we'll use one of the self-tappers to secure the other slot in our bracket there. These are provided in the kit, so you won't have to worry about grabbing them. inaudible 00:05:48 that right up. It's going to give us a nice, sturdy mounting location for our brake controller. As you can see, the brake controller, it's a nice looking, very compact unit. It has a gain adjustment right here on the top. You'll want to be sure that we mount that low enough to where that's going to be accessible. Then we'll use one of our screws, the flat tip, to go right into the side of it through the bracket. Before we get this fully tightened, we'll be able to adjust this up and down. Even if we didn't have a flat surface to mount it to, we could adjust a little bit to make up that difference. Remember, we do have that gain control here on the top. We want to make sure we've got enough room to get to that but also keep it as high as we can, which that looks like it will work out fine. Then we just tighten down our screws, one on each side to hold it in place for us. Plenty of room to get to our actuator button; plenty of room to get to our gain switch. Now we'll bring it down and plug it right into our harness. When we hear that click, we'll give it a pull and make sure it's nice and connected. Then our excess wire, we'll just put a couple of coils in that, and we'll tuck it right up in here out of the way. Use a zip tie if you got one around the house there. You can see I'm just securing it right above that little heater tube. We'll use our pliers and just trim off our excess. Now that we've got it installed, let's see how how it works. Now here you can see as we slide our activation bar over we're going to see it working, giving us our digital readout indicating to us how much braking force is going to the rear. The same thing's going work when we apply our brakes. We're going to see that work up to full power. The gain adjustment we had talked about making sure we have enough room for, it's going to be right here on top. If we move that maybe into the middle position, you'll see we're only going to get mid-force braking power there. All the way up, we'll get full gain. If we move that all the way down, you can see we don't have any. Re-adjust that, and inaudible 00:08:31 our trailer to get whatever kind of braking force we're going to need. With everything working as it should, that completes today's installation of Curt Venturer, part number C51110, also using the Universal Wiring Adapter, part number C51515, on our 2012 Chevrolet Silverado. .
