Installation of a Trailer Wiring Harness on a 2011 Nissan Sentra


Today were working on a 2011 Nissan Sentra. Were going to install toe ready T1 connector part number 118470. Weve already removed the spare tire and spare tire tools and trunk contents. Our next step is to remove the rear threshold. Were going to take a screwdriver or trim tool and get underneath the plastic and slowly pry up to release the fasteners from the sheet metal. With the threshold removed, well go ahead and set it aside.With the rear threshold removed, we now need to remove the carpeting behind the tail light.

Im going to take a small pocket screwdriver, get underneath the plastic tab, remove the center and pull it out. Ill repeat the same on the drivers side. Those fasteners removed, we can now gain access to the wiring behind the tail light. The white connector you see here behind the carpeting is the wires that run from the tail light. So we get to the locking pin on the connection point and we go ahead and take my trim tool and separate the fastener from the sheet metal.

Now you can see the locking tab on the connection tab, well simply press on it and disconnect the two. Now we can take our toe ready T1 connector and for the drivers side were going to take the yellow and brown wires and plug them inline with the manufacturers. As you can see the connectors match up identically with the manufacturers. Now I can go ahead and reinstall the mounting fastener for the connector.Now well take the red and green connector, rod over the passenger side and make the same connections. Now using several of the zip ties that are provided with the install kit, Im going to secure the red and green wire to the manufacturers and run it back over to the drivers side.

Then Ill take my side cutters and cut off the excess from the zip ties. Now, I can go ahead and reinstall the carpeting on the passenger side.Over on the drivers side we go back to my white wire with the ring terminal already attached, this is our ground wire. Were going to go ahead and attach it here directly to the sheet metal with the secured connection, our ground wire is mounted. Next we go ahead and mount our converter box but before I do that to make it a little easier on myself, well attach our power wire. The power wire is going to run up to the vehicle battery, well take one of the butt connectors provided in our install kit, slide it onto the red wire of our converter box and then go ahead and crimp it down.

The other end of our butt connector will attach to the black wire thats provided in our install kit that will be the power wire that were going to run to the battery. And I personally like to go ahead and take a bit of black electrical tape, wrap up the connection, just to help seal out any moisture, dirt or debris. Ok, now we can go ahead and mount our converter box. What were looking for here is a flat clean service so that when we peel back the cover on our 2 way adhesive, it will make a good connection and stay there for us. Back here in behind the carpeting is a perfect location. Next we need to route our power wire up to the battery. To do this, Im going to run through the manufacturing grommet here and then up to the battery. So to get my wire through, Im going to go ahead and pull the grommet out of its position, take a utility knife, cut a hole in it, so we can feed our wire through. With my wire through, I can now go ahead and reinstall the grommet and pull the wire from underneath. With our wire pulled through, we can now run it up to the engine compartment, when routing your wire up to the engine compartment you want to try and stay away from moving components such as suspension or steering and excessive heat such as the exhaust. Now we go ahead and pull our power wire up from underneath, once I get it into the engine compartment here, go ahead and run it behind all of the heat shielding for the engine, between the firewall and the heat shielding. Before we install our fuse holder, well go ahead and prep it, simply cut it in half, strip back both ends. On one end well add a ring terminal and on the other well add a butt connector. Then we can take our butt connector and attach it to our car wire. Now well go ahead and take the cover of the positive terminal of the battery, we can add our fuse holder to is by attaching our ring terminal to the battery post. With my fuse holder connected to the battery, well go ahead and install the fuse. With a couple of zip ties, I secured my fuse holder, with our power wire run and our new 4 pole connection routed into the spare tire well, we can go ahead and reinstall the carpeting on the drivers side and the threshold. To use our 4 pole connector, we will simply open up the tire cover, pull our 4 pole connector out, run it down to our hitch or accessory. You can simply close the trunk on the wire as the weather seal is thick enough that it wont harm it, however do stay away from the latch as pinching of the latch could damage the wire. There you have it for our toe ready T1 connector, part number 118470 on a 2011 Nissan Sentra.
