Trailer Wiring Harness Installation - 2003 Hyunai Santa Fe

Installation of a Trailer Wiring Harness on a 2003 Hyundai Santa Fe

Today we're working on a 2003 Hyundai Santa Fe. We're going to install Tow Ready T1 Connector, product number 118473. First, we're going to access the rear cargo area of the vehicle. I'm going to go ahead and push the rear seats forward and then we're going to remove the cargo cover and then we're going to remove the rear cargo trays on both sides and the center. Next, we'll go ahead and remove the cargo hooks from the rear frame. There's the cargo hook on the passenger's side, I'll go ahead and repeat the same process on the driver's side.

Now we've got the cargo hooks removed, we're going to remove the three fasteners that are holding in the threshold. Taking my interior trim tool I'm going to go ahead and get under that threshold now and pop it free. With the threshold out of the way, we now need to remove the interior carpeting. To do that, we've got four plastic push fasteners on each side, two more cargo hooks in the back, one on each side, and then three child safety restrains across the front. Now we need to remove the cargo door latch, take a small pocket size screw driver, go inside the latch pull back on the hold down hook and I'll go ahead and pry up on the latch on the front side and then I'll repeat the same process for the back side.

Now I'll go ahead and repeat the same process on the driver's side. With all of our plastic latches removed, I'm going to go ahead and pull out the spare tire tools and jack. With the jack out of the way, we can now go ahead and remove the cargo door lid. Go ahead and take the door off, set it out of our way. With our door out of the way, we gain access to four more plastic push pins at the very forward of the cargo trays.

With all of our fasteners removed, we can go ahead and remove cargo liner. With our cargo liner removed, we need to gain access behind the tail lights. We're going to pull back on the interior trim panels. Take my trim tool again, get them behind the panel and just gently work it free. With our panel pulled back, you can see we've gained access to the rear tail light wiring connector.

Now let's go over to the driver's side and do the same thing. You see the plug here on the driver's side On the inside wall of the plug there is a locking tab. We'll press on the locking tab and remove it. Now we can take our new Tow Ready T1 Connector. We'll be using the yellow and brown wire and you see it matches up with the manufacturer's connection. We'll go ahead and plug in to the side we've just removed then the other side we took the plug out of. We're plugging in line with the manufacturer's wiring. I'll go ahead and tuck my wires back in behind the sheet metal so they are out of the way. Now I can take the white wire with the ring terminal on it which is our ground wire and go ahead and remove the screw here at the manufacturer's ground and use it to ground our converter box. With our ground wire attached, we can go ahead and locate a suitable spot to mount our converter box. What we're looking for is a clean flat surface to attach it to. I'll go ahead and route my wires around the auxiliary socket here, peel back the cover on the two-way adhesive, we'll feed it inside the sheet metal to our flat surface. We'll press that firmly into place make sure I get a good cohesive connection. Now I'm going to go ahead and take my 4-pole, feed it out through the bottom of the interior sheet metal. This will make it easier for me to route it up from behind the trim panel. Also do that with our red and green wire which is going to be the passenger's side connection. Now we have our wires running up from behind the trip panel, we'll go ahead and feed our passenger's side wires over and make our connection. Then we can go ahead and reinstall our interior. Before we install the cargo liner I'm making sure my 4-pole connector is routed outside of it. Ok, now we've got the interior reinstalled, let's go ahead and show you how to use your new 4-pole plug. Pull back the cargo liner, remove the door, take our 4-pole route to the center of the vehicle, we'll be using it. Notice to stay away from the latch of the door and we'll just go ahead and close the door as the inaudible sticky enough that it won't harm it. And when you're finished using your new 4-pole connector simply roll it up, reinstall it in the cargo area, and there you have it our Tow Ready T1 Connector, product number 118473 on a 2003 Hyundai Santa Fe.
