How to Install a Trailer Wiring Harness on a 2013 Ford Escape

Today on our Ford Escape, we will be installing the Tow Ready T-One connector, part #118566. First, were going to begin by opening up the rear cargo access door. Then, well will remove the two fastener covers that attach to the tail light assembly on the drivers side. Once we remove the covers, we can then remove the four fastening screws here on the drivers side. Now, with the screws removed, we can go ahead and remove the drivers side tail light assembly. To do this, well gently pull and pry out this tail light assembly until it pops free.

Be careful not to break the alignment tab underneath when removing the tail light assembly. Next, to disconnect the tail light assembly completely, well press on the locking tab for the wire connector and remove it from its socket. Next, well need to connect the yellow and brown wire from our new Tow Ready harness. To do this, it will be easier to feed the wire from up underneath the vehicle. We will take our piece of air tubing or our pull wire and feed it down between the plastic bumper cover and the body or sheet metal of the vehicle.

Now, we have our pull wire underneath. Well go ahead and take the yellow and brown wire connector and use some electrical tape to attach it to our pull wire. Then we can begin pulling it out behind the drivers side tail light assembly, as we gently pull out on the plastic cover. Now that we have the connectors up behind the tail light assembly, well start making our connections. We will connect one side of the Tow Ready harness to the manufacturers wiring and the other side to the tail light assembly, then were ready to begin reinstallation.

Now with our drivers side reassembled, well move over to the passengers side and disassemble it in the same way we did the drivers side. Well feed our pull wire down underneath the vehicle and then we can get underneath the vehicle and start routing our wires. Keep in mind when routing your wires, stay away from excessive heat such as exhaust or moving components such steering or suspension. We will start with our new 4-pole connector, routing it over to the center of the vehicle. We will go up over the manufacturers fascia brackets that we will secure later on and ending up with the 4-pole at the hitch.

Then, we will take our red and green wire connector of the passengers side wiring and feed it over to the passengers side, following the same routing of the 4-pole wire and attach it to our pole wire just as we did on the drivers side, pulling it up behind the tail light assembly, making the connection, and then reinstalling. We can now go to the converter box and attach our power wire. Our power wire will be a separate length of wire provided with our install kit that we can connect with the yellow butt connectors that are also provided with our install kit. Well strip back the power wire and add the butt connector. Then, well take the power wire coming from the converter box and attach it to the yellow butt connector, adding length to our power wire for the converter box. Quick tech tip: I recommend to take some black electrical tape and wrap up this connection to help keep out the moisture, dirt and debris. Next, well take the white wire from our converter box with the pre-attached ring terminal and a self-tapping screw and attach it directly to the frame, providing ground for our converter box. Next, well go ahead and mount the converter box. To mount your converter box, well peel back the two-way adhesive cover and attach it to a clean, flat surface. Up behind the drivers side tail light assembly panel is a good location. We will now route the power wire up to the front of the vehicle into the engine compartment where we will make connection with the battery. Now, we have our power wire running up to our engine compartment. I used a zip tie to secure my power wire in the engine compartment. Next, well go ahead and take our yellow fuse holder and prep it for installation. First, well cut it in half and strip back both ends. On one end, well add a yellow butt connector, and on the opposite, well add the yellow ring terminal provided with our install kit. Well be attaching the ring terminal to the positive battery post. Well then take the black power wire and route it near the battery box where we can cut off the excess length. Well strip it back and then add it to our yellow butt connector. Once again, I recommend to wrap up this connection with a black electrical tape. With this style of battery post, the nut is not intended to be completely removed. What well to add our ring terminal is go ahead and cut a small section out of the ring terminal, so we can slip it over the post and then re-secure it. Next, we can go ahead and add our fuse to the fuse holder and then take our yellow fuse holder and wire and tuck it down between the battery box and the battery. Next, well go ahead and take a black zip tie and secure our wiring and cut off the excess from our zip ties to clean up our install look. Now, we can go ahead and replace the battery box cover. This will complete the install of the Tow Ready T-One connector, part #118566, on our 2013 Ford Escape.
