How to Install a Trailer Wiring Harness on a 2011 Hyundai Santa Fe


Today on our 2011 Hyundai Santa Fe we'll be installing the Tow Ready T1 Connector, part number 118415. To begin our install we'll need to remove the rear threshold from the vehicle here at the trunk. We'll pull the handle here opening the door. To remove the threshold we'll peel the rubber molding away which will allow us to bet underneath the threshold. With our rear threshold loose we already moved the jack tools. We'll undo the three bolts that hold the tray in place.

Next, we're going to go ahead and remove the side panel covers to access our tail light warning. And you'll see down here in the cover is our plug that we'll be using. We're then gonna use a piece of hard air tube as a fish line. We'll run it through behind the panel and now the hole here is the bottom of the panel. We can then take our T1 connector for the left side and attach it to our air hose.

Before we attach it to our airline we're going to go ahead and take our white ground wire and peel it from the yellow and brown wire because in order to make a good ground with this vehicle we'll need to leave the wire down by the T1 module box. Now, we'll attach our connectors using some electrical tape. We'll then feed our connector up through the hole and bring it up to our connector. We can then remove our electrical tape and we'll set our air line aside for use on the passenger's side of the vehicle. We can then go to the connector here at the factory harness, unplug the tail light assembly, plug in our T1 connector on one side and in the other side we'll plug back into the factory harness which will make our connections.

We'll now go ahead and make our ground. We use the self-tapping screw supplied with the install kit before they threw the island over white water in finding a piece of sheet metal, we use our drill. Now our modulite box comes with a two sided tape already attached to the box itself. We'll simply peel the adhesive backing away and attach it to the inside of the vehicle underneath the paneling. We can now extend our red and green wire to the passenger's side.

Now that our connections are all made we'll, bend our four pole connector out and we're going to go ahead and bring the connector out from the sides between the tray and the side panel itself. So after determining that we can go ahead and reinstall our tray, we also want to make sure that your red and green wire is tucked away so that when the tree is reinstalled it doesn't interfere with any of the clips. I could simply bundle up the 4-pole harness and store it down here in the tray. When you need to use it, you simply open the Tray, bring your harness out and to the back of your vehicle to make your connection with tour trailer. You can then simply close the door on the wires because the molding is padded enough that it will not crush the wire. However, you do need to stay away from the locking mechanism on the rear door as that could damage the wire. And that will complete our install of the Tow Ready T1 connector, part number 118415 on our 2011 Hyundai Santa Fe.
