Today, on our 2008 Kia Sedona, well be installing the Draw-Tite Brake Controller, part number 5100. Well be connecting with our ETBC-7 install kit. Well also be using the Tow-Ready Universal Mounting Bracket, part number 18136. Our first step will be assembling the 7-pole mounting bracket to the 7-pole connector. Well be using the hardware provided with our install kit. With that completed, we can now go ahead and connect the 7-pole bracket to the tow ready universal mounting bracket.
With that done, well use the hardware from the mounting bracket to secure it to the hitch. As we do that, well take the wires and feed them through the bracket so they go up over the hitch. Now, with our bracket secured, we can start making connections with our wires. Well take the 4-pole plug from our 7-pole and the 4-pole plug already on the vehicle and make our connection there. Note, I will cut off the end of the vehicle side 4-pole bracket as it will be in the way to tape up and seal up this connection point.
Next, well go ahead and take our gray duplex wire, strip back a couple inches, and then strip back the wire so that we can make connections with our 7-pole wires. Well take the black from our duplex wire to the black wire on the 7-pole connector to make the connection with the yellow butt connector already pre-attached to the 7-pole. Next, well take the white wire, connect it with the blue wire from the 7-pole connector. This will be the brake power circuit going to our trailer or accessory. Now with those connections made, well go ahead and cut off the excess from the purple wire, as it will not be used in this application.
Now were ready to go ahead and take some black electrical tape and wrap up our wires. With that done, Ill use a couple of black zip ties to secure my wiring to the hitch as we route it over to the vehicle frame on the driver side. There, well take the white wire with the pre-attached ring terminal and a self-tapping screw and attach it to the frame for a ground to our 7-pole connector. Next, well go ahead and take the rest of our gray duplex wire and route it where well pull it up into the engine compartment. Stay away from excessive heat such as exhaust, or moving components such as the steering and suspension.
Now with that done and our wires secured underneath the vehicle with black zip ties, we can go ahead and strip back the sheathing on our gray duplex wire as well be routing a black wire to a breaker underneath the hood and the white wire will go in to the cabin of the vehicle where it will connect with the blue wire coming out of the brake controller. Now with our wire stripped back and ready to be fed into the cabin, well first need to go ahead and drill a hole to the firewall and install a grommet. Well drill a 7/16 hole through the firewall and install a Snap Bushing Grommet, part number SWC8057. Now with the hole drilled out and the grommet installed, well go ahead and feed the white wire that we just ran from our 7-pole connector into the cabin of the vehicle. Ill then use a piece of blue tape to mark it as the wire that will connect to my blue wire coming out of the brake controller. Now, we have the white wire marked with our blue tape. This will indicate our blue wire coming from our 7-pole connector at the back of the vehicle. Well need to mount two breakers. To make room, well cut back some of the insulation here on the firewall. Here, well mount the 40-amp breaker that will supply power to our 7-pole connector at the back of the vehicle. The other breaker will be our 20-amp breaker which will supply power to the brake controller. Next, we need to go ahead and route a power wire from our 40-amp breaker to the positive battery terminal. Well go ahead and use the leftover wire from our gray duplex cable. Well simply strip back one in at our ring terminal and make our connection to the breaker. Next, well take the leftover wire from our duplex wire, the white and black wire, which will essentially become the power and ground for our brake controller. Well feed it through the firewall. We can go ahead and start making connections with the wires that weve run. We have the red wire from the brake control switch, which we identified earlier as a white wire coming out of the brake switch then we attached the red wire to give it some length to reach the pigtail coming from the brake controller. Now were ready to go ahead and mount the brake controller. We will be using the bracket and screw provided with our install kit for the brake controller itself. Now with the brake controller mounted, to make our connections, well simply strip back the ends of each wire and use the butt connectors provided with our ETBC-7 kit to connect the power, ground, and our blue wire. Now with all our connections made, we can simply take some black electrical tape and wrap them up. Now that thats completed, Ill go ahead and take a couple of zip ties to secure my wiring. Next, now that were back in to the engine compartment, we need to route the white and black power wires for our brake controller. The black wire will route to the 20-amp circuit that we mounted to the fender well and the white wire will route to the negative battery terminal. Now with our wires routed, well go ahead and strip them back at a ring terminal and make our connections. Then, well route it over to the battery. Next, I will go ahead and tighten down the three connections that weve made to our breakers thus far. Now, we can go ahead and run our power wire for our brake controller off the copper terminal to the positive battery terminal. This will be from our 20-amp breaker. Next, well go ahead and remove the positive battery terminal cover. This will allow us to loosen one of the positive battery terminal nuts where well be adding our power wires that will route to our circuit breakers. With both wires now routed from the breakers to the positive battery terminal, well cut off any excess, strip them back and add the ring terminals. Now that thats completed, we can go ahead and attach it to the positive battery terminal and secure them there. Now with our connections made and secured, well go ahead and reinstall the positive battery terminal cover. This will complete the install of our Draw-Tite Brake Controller, part number 5100 in conjunction with the ETBC-7 installation kit, our Snap Bushing Grommet, part number SWC8057, and our Tow-Ready Universal Mounting Bracket, part number 18136, on our 2008 Kia Sedona.
