Installation
This custom-fit T-One connector plugs into your Jeep Wrangler Unlimited's wiring harness, which is located behind the driver's-side tail light. You will have to remove the tail light assembly to access this harness.

Once installation is complete, the 4-way flat connector will be stowed beneath your Jeep Wrangler Unlimited, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Today on our 2013 Jeep Wrangler Unlimited well be installing Tow Ready T-1 connector, part number 118416. To begin our install well need to remove the drivers side taillight assembly. Well remove the two inside screws and then pop the taillight assembly out of its position. Here we can gain access to the manufacturers wiring and well disconnect the taillight assembly from the wiring by pressing on the locking tab and pulling the connectors apart. Next, well set the taillight assembly aside and take our Tow Ready Harness and feed it down through the opening and then underneath the foam cover at the bottom of the drivers side quarter panel. This will feed our four pole underneath the vehicle.
Now with that done well go ahead and take the white wire with the pre-attached ring terminal and ground it to the body or sheet metal of the vehicle. Here on the drivers side visible through the taillight opening where the sheet metal doubles up will be a perfect ground location. Using the self-tapping screw provided with our install kit, well go ahead and run it into the sheet metal securing the ring terminal. Now with our ground installed were ready to go ahead and reinstall the taillight assembly. Well plug the Tow Ready Harness into the manufacturers wire and the other end of our Tow Ready Harness into the back of the taillight assembly.
Then well go ahead and reinstall the taillight assembly securing it with the fasteners. Next well get underneath the vehicle and start routing the wire over to the center of the hitch. Im going to feed it up over the body mount, go through the frame and then to the hitch. Now well go ahead and secure the wire using several black zip ties onto the back side of the hitch to protect it. Any excess from the wire can be fed back up and behind the taillight housing and well secure it with a zip tie through a hole in the body making sure the foam pad is reinstalled.
Well go ahead and cut off the excess from our zip ties. And this will complete the install of the Tow Ready T-1 Connector, part number 118416 on our 2013 Jeep Wrangler Unlimited.

i received and installed the receiver hitch and wiring kit for my 2013 wrangler. the wiring harness went in without any problems in about 20 mins. the hitch took about 30 mins. easy, quick, and no problems. the only thing i couldn't understand is why the instructions tell you to drop the muffler. this is not necessary as there is ample room to insert the 4 mounting bolts. overall, i'm very happy with the product and the service i received. 61491

Order received a day after the estimated date. No problem, that's the USPS for you. Installed the harness. The video says about 5 minutes. They are close. The only issue that I had was difficulty finding a place to drill and attach the white ground wire. Basically a plug and play harness. I wish that I had ordered a mounting bracket. The one that is on my 2011 Jeep Wrangler Unlimited is a bit large and the plug is too small to stay put once it is in the bracket. Will manufacture something to hold the plug so that it stays in place. 71794

Thank very much for such fast shipping and a excellent product. Hooked up in 15 degrees out side and in the pitch dark, and it only took about 25 mins. It took that long because I lost my tail light screws. Just wanted to say thank you again. Dustin Slifer63959

Easy install. Hard to get a drill in the Driver's side opening to install the ground wire with a tek screw. Ended up finding an existing hole inside and down to the right of the taillight opening. Attached the grounding eyelet there with a small bolt, washer and nut. Works perfect and no new holes in my Jeep. Harness is plenty long, works perfectly. Zip-tied it up nice under the frame.49496

Fast delivery of good product. Installation was easy with clear instructions. Only complaint is that the wires leading from the left light on the cargo rack should be about 6" longer. I had to position the vehicle connector so it projects beyond the bumper to allow the cargo connector to be joined.46183

This wiring harness went in really, impressively easily on my 2012 JK. Absolutely no problems; so easy a child could do it... or someone with almost no handyman experience. The one exception is that you have to decide where to sink a self-piloting screw into the frame to ground this adapter. You need a solid, torquey corded drill (I had a Hilti hammer drill), a hex bit adapter to get the best hold on the screw, and I went straight into the thick iron frame of the Jeep. For that last piece, you may want to consult a handy friend or the support staff on this site. Drilling holes into your beautiful bone-stock Jeep should always be done carefully.45905
