Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required.
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.
Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, 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 2008 Ford Focus, well be installing the Tow Ready Custom Fit vehicle wiring harness, part number 118457.Now to begin our installation, we'll open the trunk. With the trunk open, we'll need to temporarily disconnect the drivers side tail lamp. To do this, we'll undo the two plastic screws here on the drivers side holding in the plastic trim just behind the taillight.Then using some gentle force, we'll pry the trim away where we can move it off to the side. We'll then take a 10 mm socket and remove the two nuts off the taillight studs here.With that done, we'll use a pry tool to pry back on our taillight and remove it from the vehicle. Now this exposes our connector here that we'll T into. Now with our drivers side taillight out, we'll go ahead and repeat the same procedure and remove the passenger side taillight.Now that we have both taillights out, we'll take our new wiring harness and we'll route our four pole and the connector with the green wire to it down underneath the vehicle through the hole here between the body and the bumper cover.
We'll take the connector with the yellow wire in it where we can now remove the factory connector from the back of the taillight, take our new connector, plug it into the taillight and the other side into the factor wiring. With that done, we can now go ahead and reinstall our drivers side taillight. We'll also go ahead and reinstall the inside panel as well.We'll now move underneath the vehicle where youll see here on the drivers side between the body of the vehicle and the rear bumper cover is the harness that we routed down. We'll pull it down and route it over toward the passenger side of the vehicle. Now the four pole will stay in the center of the vehicle here by our receiver tube.
We'll take the green wire and continue over towards the passenger side where we'll pass it up through the hole between the bumper cover and the body of the vehicle towards the passenger side taillight opening. Well reach down and pull it up where we can now attach it to our passenger side taillight by removing the factor connector and installing the T1 connector in.Now here on the passenger side, youll also notice that there is a white wire with a ring terminal. This is a ground wire. We'll need to find a suitable ground here on the body of the vehicle and using the self tapping screw that comes with the kit, we'll ground the white wire. Now with the white wire grounded and our connection made, we'll go ahead and reinstall our passenger side taillight the same way we did the drivers side.Now with everything done here in the trunk, we'll go ahead and close the trunk deck lid and move back underneath the vehicle.
Underneath the vehicle here, all we'll need to do is to clean up our install look using a few zip ties. We'll tie the wiring harness up to make sure it stays out of the way. We'll also go ahead and use the cover for the four pole to hook it to our hitch.Once we have everything secured, we'll go ahead and take a pair of side cutters and snip off the excess zip tie which will complete our installation of our T1 vehicle wiring harness with four pole connector part number 118457 from Tow Ready on our 2008 Ford Focus.

Other than UPS not noticing the apartment number in my address and getting it a day late, very fast delivery. The box was a little damaged but the product was unharmed. I had a friend install it for a case of beer...he's pretty mechanically inclined, so it was not too difficult for him to install. The only thing he had a little issue with was getting the wiring installed. To get the hitch and wiring installed, it took about 1.5 hours, including breaks and not using a lift like a professional shop would have. I bought this so I could update/upgrade my current bike rack to a more stable one, and use a trailer if needed. I don't have the rack yet, and won't be moving for a month or so, but I have a feeling I'll be glad I have the hitch when the time comes. 180764
Installation not too difficult, however the wiring is all exposed under the vehicle and not through the trunk as in normal trailer wiring. The exposed receptor wire just hangs down behind the bumper and somehow must be stored so it does not get snagged on anything. Looks bad wrapped around the hitch and all exposed! 50957

Great product! Installation very simple. Instructions very easy to understand. I had a technical question about possible circuit overloads and the folks @ e trailer were very helpful too. Excellent tracking during shipment as well. I will make this my first stop for any future need. Strongly recommended! 25127
My wife and Installed the hitch in a little over an hour. If fit pretty good. It took a little longer because we did it on the ground. This made it harder to lift into placed. The video from your web site was a great help. I would recommend this product and your company to any do it yourself-fer out there. 53970
Worked on my 2011 Ford Focus perfectly. I am not an auto guy and installation was super simple and easy. Very little tools and no special ones. Would highly recommend. Using etrailer, this is my 3rd time. Each time has been the same. Easy to shop, right product, shipped on time. 14463

I installed the Curt hitch and T-One Wiring Harness. Both great products and installed easily. A tip for anyone doing the same on a 2008 Ford Focus, would be to do the wiring harness before the hitch. I put the hitch on first and it was in my way for doing the wiring. 42847

It's a wiring harness so there's not much to say. The wiring harness was an exact fit to my car. The instructions were clear and accurate. It was easy to install and it works. Exactly what I hoped for. 53063

Access to the connectors was a bit of a hassle but that is Fords problem. Cable was easy to route and the connectors fit perfectly. 50617
