How to Install a Trailer Brake Controller on a 2014 Toyota Tundra


Today on our 2014 Toyota Tundra, we'll be installing the Hopkins InSIGHT Flex-Mount Break Controller, part # HM47297. To install this break controller, we're also going to use the Hopkins Plug-In Simple Brake Wiring Adapter, part # HM47815. Now to begin our install, we'll first locate the manufacturers tow port so that we can plug our Direct-Fit Wiring Harness into it. Here on the driver's side kick panel behind the parking brake pedal, we can locate the manufacturers tow port. As you can see it's taped up to the main wiring harness, so I'm just going to use my utility knife to cut the tape and pull it free. Now that we've got the tow port free, we can take the white connector end of our Direct-Fit Wiring Harness, plug it directly into the manufacturers tow port. Next, we'll go ahead and route the four pull connector over to where we're going to mount the brake controller box. When routing your wires, stay away from any moving components such as the gas, brake, or emergency break pedal.

To safely route it, we're going to go along the firewall and around the parking brake pedal. Here's our Hopkins InSIGHT break controller box. The box has a total of three ports: we have the pigtail which will connect to the four pull harness we just ran, then the larger port is the plug or outlet that we will connect to for our display screen, and then the other outlet or smaller outlet will be the connection point that we'll plug into for the manual override and adjustment to the brake controller. Now that we've identified the box and ports, I'm going to go ahead and remove the electrical connections until we have the box mounted. Keep in mind when mounting the box that it'll need to be mounted flat to the vehicle console or kick panel. Keep the box level and securely mounted. For this application, we're going to mount ours to the console up underneath the dash.

We'll use the self tapping screws provided with the install kit to secure it. Now with our box securely mounted, we can start installing the display. Our display screen is going to get mounted up the dash in front of the steering wheel. To help hide my wire, I'm going to run it between the steering wheel and the dashboard. Now to mount the display, we'll turn it over and use the two way adhesive tape provided to secure it. One side of the tape will go to the mount, then we'll peel back the other side and attach it to the dash. Next, we'll go ahead and mount our InSIGHT manual control and adjustment.

To mount it, we'll use a two way adhesive provided, again, peeling back one side and attaching it to the control and the other side we're going to attach to the dash. If I have it firmly pressed in place onto the controls. Keep in mind when mounting the manual controls, you want to keep it within reach of the driver in case of emergency use. We're going to put ours here on the knee bolster, and then we can just run the wire down and underneath the dash. Now we've got all our wires routed. Down here to the control, we'll start making our connections.

The larger point connection point was our display, smaller one is the manual control, and then we have the four pull harness. Now with all our connections made, we'll go ahead and take the zip ties provided with the install kit and secure our wiring up underneath the dash. Once we've finished securing the wiring, we'll go ahead and cut the excess from the zip ties to clean up our install look. Now with our new system on and secured, we've got our manual display with the digital readout, and then our manual braking which can be actuated by simply sliding the bar down, and the more we slide it, the more power or braking is supplied to the trailer. Here on the side is the plus and minus adjustment for increasing or decreasing the amount of power that we send to our trailer braking so we can adjust for trailer load. Next we'll go ahead and hook up the trailer. Now with the trailer brake hooked up, you can see we have the light indicator showing that he have a trailer brake connection, and if we hit the brake pedal, we get a display indicating that we're sending power to the brake controller. We can also test the manual function and we see that as we increase the manual side, it increases the power we're sending to the brake controller. With that, we're now installed and tested, and ready to hit the road. That'll do it for the Hopkins InSIGHT Flex-Mount Trailer Brake Controller, part # HM47297 in conjunction with the Hopkins Plug-In Simple Brake Wiring, part # HM47815 on our 2014 Toyota Tundra. .
