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 Draw-Tite Activator IV. This time-delayed brake controller is capable of controlling 1 up to 4 axles. The part number on it is 5504. We're also going to be using the replacement brake control plugin harness, part number 20127. Here you can see once it's installed. As we activate the switch we're going to see our gain lowering and rising indicating that we've got it hooked up properly. Now a couple of nice features about it are that currently we've got our gain set to 10.

As we bring it in, it's going to peak out at 10. We've got the up and the down button right here. Pressing down, as you can see, that's going to bring that gain down, reducing our maximum braking power being sent to the trailer. It's going to allow us to fine tune it in half-digit increments to really get it right where we want it. Another great feature .. I'll run that back up to high power ...

It's going to be the two Sync buttons that we have here on the right. This is adjustable from 1 all the way up to 9. That means when we hit our brake when its Sync is at 9 it's going to rapidly go to our highest gain possible. As we bring that Sync down .. we'll move it down to about half power ...

you'll see those numbers are going to rise more gradually, giving us full braking power at a slower increment. If we bring that all the way down, it's going to very slowly work its way up. This is important because this is going to help us to determine how harshly or how smoothly our brakes are applied to our trailer, allowing us to again, customize that feel we get when we hit those brakes. 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. As 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 it. Here you can see once we get that cut off, it's going to list what each of our wires are for so 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 we can start hooking up our harness. Now our harness is labeled ground, stop, power and brake output. We just want to match that up with what we've got here and make sure we get it all done. This says white is ground so we'll connect our white wire with our white wire. To do this we're just going to use butt connectors today. Make sure that's got a nice hold and then pull that end off our wiring and connect our ground to our ground. One down, three to go. Now our red wires are stop, so that's going to be our brake switch wire. That's indicated by the blue and white wire here. We'll get that one crimped down. Now our blue wire here which is our brake output wire, that goes into the dark blue or the Aux or the auxiliary. Let's bring that down, make those connections. The last one we've got to hook up is our power. That's going to be our black one here, Power. That runs to the one that says battery here, BATT. It's battery. It's going to be the red and black wire so it's going to be the one we've got right here. Now that's it for our connections under here. You do see the orange wire here. We're not going to be using this one so that's one that we'll kind of bundle up here with our harness and then we'll kind of wrap it down with some black tape. Then just depending on how nice you want everything to look here, you can continue on down your harness and give it a nice clean look. Once we get down, all we're going to be left with is a nice, good-looking wire loom there and then the plugin will go right into the back of the brake controller. Now we're going to be installing the bracket to hold our brake controller in place. We'll want to do this with a nice flat surface. As you can see there is one here. We're actually going to be able to take advantage of one of the factory screws right here that hold the bottom of the dash up. We can slide our bracket right up behind there, line it up with the hole that's already existing and it will save us putting any more holes in the vehicle than what we have to. Thread the screw back into place and then bring in one of the self tappers that are included in our kit to secure our other side here. Now we bring in our brake controller. We have the option of setting it at a lower height or a little bit higher. You just want to leave yourself enough room to where you can get at your Gain and also your Sync buttons. Slide it up into place and then we've got a couple of self tapping screws that are provided with the kit that are going to go in each side. Then after we get it kind of positioned where we want it . I usually let it come kind of down because we do want to access those buttons we had talked about. we can go ahead and tighten them up. Now let's plug it into our pigtail here, give it a tug and make sure it's nice and secure. Then all we have to do is tuck our wires up here and get them out of the way. Nice and neat up there out of the way where we won't catch it with our toe or anything. We'll just bring a zip tie around it. We've got plenty of wire up there if we ever need to make any changes or anything like that but we want to be able to . being down here and getting hung on our foot all the time. With everything working as it should, that's going to complete today's installation of the Draw-Tite Activator IV, part number 5504, using the replacement brake control plugin harness, part number 20127, on our 2012 Chevrolet Silverado. .
