How to Install a Wiring Harness for a Trailer on a 2005 Hyundai Santa Fe
Today we are going to be installing wiring harness part number 118473 on a 2005 Hyundai Santa Fe. Taking a look at the wiring harness, you can see we have got two main ports coming off of the Modulite box. We have got one with the yellow and brown wires. That one is going to connect behind the drivers side tail light assembly. The other connector, with the green and red wires, is going to be connected behind the passengers side tail light assembly. We have also got a white terminal here on the drivers side connector. That is for the ground, securing that to a metal surface. The black box in the middle is our converter box. And then, coming off the other end, we have got our 4-pole connector. And that will be staying inside the vehicle in this application.
Okay, now we are inside the cargo region of the Santa Fe here. And our connection point is going to be located behind the tail light assemblies on the inside of the vehicle. To be able to gain access to both of those points, we are going to need to remove the interior. Also we have to remove these components here at the bottom, which will also allow us to remove the rear threshold piece. And that is where we are going to route the wires from one side to the other. With those screws removed, we can remove the rear threshold piece.
We will also be removing two side compartments as well. And we will want to come in behind the panels here and gently pry those away as well. And with the panel pulled back here, right below the speaker, you can see the connector that we are going be tapping into. We want to depress this tab right here on the inside, and that will allow us to pull the connectors apart. Okay, with those pulled apart, we want to put our harness in line and just feed our wire below the panel here. You will also note here on the drivers side we have got a common grounding point. Taking our white wire, with the ring terminal on it, and connecting it to that point as well. Next, we are going to go ahead and take and adhere our black box to a metal surface in here. We will probably feed it right through that hole, that opening here toward the fender well. Or you can actually feed it inside this compartment here.
And now we just want to go ahead and put everything back together. Our 4-pole connector, I am just going to feed below and out the open compartment here. Okay, with the interior of the vehicle put back together, you can see we have got the 4-pole coming out here. When you want to use it, you can pull it out the rear tailgate and close the door on it. And the weatherstripping will prevent it from being pinched, so you do not have to worry about that. When you are not using it, you can leave it either stored just here in the rear. This will conclude the installation of wiring harness part number 118473 on a 2005 Hyundai Santa Fe.
