Curt T-Connector Vehicle Wiring Harness
Can be used with 5-pole, 6-pole or 7-pole adapters.
Installation: Connection points are located behind the vehicle taillights. Quite a bit of trim panel removal will be necessary to gain access to the connectors. A nylon removal or plastic clip removal tool is recommended. A 10 amp fuse is also included (should be placed in slot 30a in vehicle's fuse panel) to activate the 12 volt battery hook-up. The 4-pole trailer connector will be stowed in the trunk when not in use. A mounting bracket is recommended.
Tech Tip: It is always a good idea to apply a small amount of grease to all electrical connections to help prevent corrosion.

Today we are going to show you the installation of part number 55571 from Curt. We are going to install this on a 2005 Nissan Murano. For this install what we need to do is open up the back hatch and remove some inner panels. Both of the covers on the left and right come off. These compartments will also come out. Now to remove the threshold what you want to do is remove this little panel underneath the hook. There are also 3 plastic releases in the back along with these 3 rivets in the back. Take those out and this whole panel will unsnap and come apart. We need to take this cover off so what we do is work it a little loosely and the pop this handle out and you can pull the whole thing out pretty easily. Then go ahead and pop those pins out of the side paneling so you can pull it off. Now you can see where the harness and the tail light connect.
So we will pull those apart and then plug our T connector right in there. Push that back in there and run that along the harness. Hold that together with a couple zip ties. At this point we can go ahead and reassemble the passenger side. It is also a good idea to run a few zip ties across so that the harness does not get in the way of the spare tire if you ever have to use it. Then our black wire gets connected to our power supply right here. Then we go behind this panel and do the same thing we did on the passenger side. Again we are going to route this harness along the original harness. Next we need to run our ground wire to our assembly screw and we will use this one right here. Now we will want to run this out to the outside. There is a gromit right here we can pop out and it gets replaced by the new gromit. This plug is suppose to go through this hole but it is over sized so what we will do is put a notch in it. We made a cut on both sides and pulled up the middle to make a tab. We will put this back through and tap it back into place. Next we need to secure our box here and we are set to go.
Push it as far as it can go back and make sure that the compartment does not sit on the box because it will sit uneven. Here we will start reassembling our interior then we will move down bottom side. Down here we will connect our harness then route it in a way that it stays away from the exhaust as far as possible. We ran the wire around the exhaust so it will not get burnt or anything. Now we will install our bracket which is part number 18140. We ran our wires through the hole in the bracket here. Then ran it through the final bracket that holds the 4 pole then we will zip tie the rest of the wires out of the way. That covers our install of part number 55571 from Curt on our wired connector. Installed on a 2005 Nissan Murano. The bracket number we used was 18140 which was the one that clamped to the and the other part that held the 4 pole was 18144.

Easy to install and it works. Quality item that was a breeze to install. Wish there was a flat 5 pole plug integrated vs. having to buy/install an adapter.1790

Excellent product..... Had no problem in installing ...... took about one hour to complete the project..... Video was very helpful..... everything was matched by the connectors..... Someone knew how to write excellent directions on the installation of the 55571... The video did help on one part (where to place the black box in the compartment)12989

As with the hitch I purchased through eTrailer, this product matched the description, and the installation matched the installation video. Another good purchase.28338

Video was a huge help, thanks. One clip separated from panel but I reglued it. Used a very fine tooth hack saw blade to cut two 1/4 inch long slots, and then bent up resultant tab to get 4x1 plug through body. Tapped tap back down and cover with grease as rust preventative. Cut hole in rubber plug with X-Acto knife to seal around harness and then used RTV sealant. Note: if you are testing the plug with a volt meter after installation, you'll be surprised to see +12V at the yellow, green and brown wires. eTrailer said this is OK. It worked fine when connected to a trailer.26456
