How to Install a Trailer Brake Controller on a 2012 Ford Van


Today on our 2012 Ford Van well be installing the ETB C7 brake controller installation kit, part number ETBC7 in conjunction with the Tekonsha P2 brake controller, part number 90885-3034P. The first step of our install will be installing the seven pole bracket onto our new seven pole. Well go ahead and use the hardware provided with our installation kit. Well drop the screws through the seven pole and then secure them with the nuts on the back side and tighten them down. Next we can then go ahead and secure the seven pole bracket directly to the bottom of the bumper using some self-tapping screws. Before I feed the wires over the hitch Im going to go ahead and use some black electrical tape to wrap them up, to help in protecting the wires and cleaning up our installed look.

On this application we will not be using the purple wire, so were going to go ahead and cut it off now and then complete wrapping up our wires. Next well go ahead and take the manufacturers four pole and connect it into the back of the four pole of our seven pole connector. Note, Ill also be using some dialectic grease between the two connectors to help prevent corrosion over time. Next well take our grey duplex cable, strip back a couple of inches and then strip back the two wires. This will allow us to connect them to the black to black wire and white to blue wire, coming from our seven pole connector with the free attached butt connectors.

Now with all our wire connections made well go ahead and continue wrapping up with the black electrical tape. Next well take our ground wire, feed over to the frame our cross member and use the self-tapping screw provided with our install kit to attach it. This will be the ground wire going to our seven and four pole connector. Next we can begin by starting to route the grey duplex cable, up toward the engine compartment. Before I go an further Im going to go ahead and secure the wiring from our seven pole connector to the back of the hitch.

Because of the size of this hitch well be joining two zip ties to get around the entire width of the hitch. As we feed our grey duplex cable along the inside of the frame rail, following the manufacturers wiring well use our black zip ties to secure the wiring. Note near the cab of the vehicle where the frame becomes boxed were going to go ahead and use a pull wire, or in this case a piece of air tubing to feed through one of the access holes in the frame and back out the end of the channel. Then we can take our grey duplex cable, using some black electrical tape and attach the grey duplex cable to the pull wire. Now we can go ahead and pull our duplex cable through the boxed channel portion of the frame and feed it out toward the engine compartment.

Note well be using this grommet here to feed the white wire into the cabin of the vehicle, as our black wire will continue on up into the engine compartment. Next Ill go ahead and use a paint marker to mark where well need to cut back the grey duplex cable. Now with our wire marked well pull it back down where we can gain access to it and use our utility knife to slice the cable, pull it back and then remove it. Now well go ahead and get into the cabin of the vehicle and locate the grommet from up top. Pulling back the liner you can see the grommet, and we can take our utility knife and cut a small hole in it. This will allow us to feed our wire into the cabin of the vehicle. To make it easier to route our wire into the vehicle well go ahead and take the pull wire, feed it through the grommet and down underneath the vehicle. Then well take the white wire and attach it to the pull wire with our black electrical tape. Next well go ahead and pull it up into the cabin of the vehicle. Then Ill go ahead and remove the pull wire, attaching it to our black wire and feeding it up into the engine compartment. As you can see our pull wire is here in the engine compartment and were going to route it over to the drivers side inner fender well. There we can go ahead and leave it at this time. Now were going to move into the cabin of the vehicle and start making our brake controller connections. To make our brake controller connections well first need to locate the manufacturers plug. On this application its located behind the coin holder, so well need to remove this tray. Using an interior trim panel tool and a flat bladed screw driver we can gently pop it out of position, locate the plug, press on the locking tab of the connector and remove it. Then, just below the tray the wire is secured. Well need to pop this plastic fastener free so that we can route the wire down underneath the dash where we can gain access to it. Now with the plastic push pin connector free well go ahead and push the wire down and pull it out underneath the dash, where well route down near the HV/AC vent. The manufacturers plug will match the plug that came with our brake controller. This will feed brake switch power and ground for our brake controller. Well still need to run power wires for the blue wire which will connect to the white wire we ran from our seven pole connector, and an additional power wire that will connect to the black wire that runs to the brake controller. Now we can take the white wire that we ran from our seven pole connector, run it into the cabin of the vehicle and over to the manufacturers plug, where weve already gone ahead and connected the direct fit pigtail for our brake controller. On this application the manufacturers blue wire that connects to the blue wire on the brake controller pigtail is not hot, or connected, so well need to cut the blue wire, strip back one end adding a yellow butt connector, and then connect the white wire to the blue wire. Well cut the wire on the brake controller pigtail side. Now lets go ahead and set that aside and install the brake control pocket. Using the screws provided with our install kit we can go ahead and secure the pocket to the dash on the drivers side below the steering wheel. Once we install the brake controller it will sit in the pocket like this. To make it easier to secure the white wire to our pigtail well go ahead and disconnect it, secure it with the yellow butt connector and then reconnect it to the manufacturers plug. Now I can go ahead and wrap up the end of the brake control pigtail with some black electrical tape to clean up the installed look. Then well go ahead and put our brake controller in the pocket, securing it in place. For this application the power lead to the brake controller is also not hooked up, so well need to run a power wire to the battery, taking a piece of the leftover black wire from our grey duplex cable we can feed some into the engine compartment, cut off any excess and then well strip back the one end, add a yellow butt connector and then cut the black wire again on the brake controller pigtail side, strip back the end and secure it to the yellow butt connector. For this application weve run the leads for the power for the brake controller and the trailer brake power coming back out of the brake controller to our seven pole, and then to our trailer. Well still be using the manufacturers ground and brake switch signal power. Now well go ahead and take a pair of side cutters, cut off any excess from our zip ties and then wrap up our wires with some black electrical tape to clean up the install look. Then well go ahead and reinstall the interior trim panel that we removed to get to the manufacturers plug, and well move back to the engine compartment. Here well need to go ahead and mount the breakers. Our power wire running from the seven pole connector will be connected to the 40-amp breaker and the brake controller for this application will be using the 20-amp breaker. Well go ahead and secure it to the fender well here in the engine compartment on the drivers side. Once we have the breaker secured well go ahead and take the power wire, run it to the breaker and cut off any of the excess wire. Then well strip it back and add one of the small ring terminals. Once we secure the ring terminal we can go ahead and attach it to the silver side of the breaker, because the copper side will be for our hot lead connected directly to the battery at the positive battery post. Note as we route our wires well go ahead and take some black zip ties provided with our install kit and secure the wiring out of the way. Now with the power wires secured were ready to go ahead and create our hot leads. Well take the wire remaining from our grey duplex cable, add ring terminals to the ends and then secure the large ring terminals to our two hot leads. Once we install the star washer and nut, securing all our wires to the breakers well go ahead and tighten them down. Note for this application we can pick up our power at the battery post at the fuse box. Well simply go ahead and open the fuse box cover and remove the nut from the terminal, then take our ring terminals that we secured to the hot leads, install them onto the post and then resecure it with the nut. Once we have that secured well go ahead and close the cover on the fuse panel. Now Ill go ahead and finish securing my wires and then well cut off the excess of the zip ties with a pair of side cutters to clean up our install look. That does it for the install of the Tekonsha Prodigy P2 brake controller, part number 90885 in conjunction with our brake control install kit, part number ETBC7 on our 2012 Ford Van.
