How to Install a Trailer Wiring harness on a 2000 Subaru Outback Wagon


Today on our 2000 Subaru Outback Wagon, we'll be installing the Tow Ready T1 Wiring Harness with 4-Pole Flat Trailer Connector, part number 118461. To begin with, we'll need to go ahead and raise the rear hatch of the vehicle. We'll then need to go ahead and lift the center carpet cover up out of the way. With that set out of the way, we can go ahead and over here on the passenger side, life the small carpet area out of this side. It does have two small tabs so you will need to pull up gently. Next we'll go ahead and remove the center Styrofoam section that is a holding tray as well as covering the spare tire. Then there's another piece of foam that will need to be lifted out of the way as well.

As you can see, once we lift that up, right here is the connector that we'll be plugging our T1 connector into. Now you'll also see on this wiring harness, it already comes with a 10 amp fuse installed. We'll go ahead and take our ends of the wiring and plug it into the factory wiring harness, making sure that we feel it snap into place. Now we'll need to go ahead and find a location to mount the converter box. We'll go ahead and use a little bit of rubbing alcohol on a paper towel to clean up the area before we use the double-sided tape to hold it in place. With the area cleaned up, we'll go ahead and peel the back off the double-sided tape and firmly pres the converter box into place.

You want to make sure that you set it out of the way enough that the Styrofoam insert can go back in on this side. We'll also go ahead and route the wires up underneath enough and bring it to the back here so we can ultimately stow them in the center Styrofoam section above the spare tire. Now to keep the wire from being crushed, we'll go ahead and use our razor knife here and take out a small section of the Styrofoam insert to allow the wire to pass through it. Now we'll go ahead and re-install the rear hatch area in the reverse that we removed things. Now when not using your 4 flat, you can stow it in the Styrofoam cover just above the spare tire, and when you are using it, you can go ahead and pull it out and it will not be crushed by the weather stripping when you close the rear hatch. Make sure you keep it away from the center latch so it is not damaged. Now we'll go ahead and test the 4 flat wiring.

As you can see here, everything's working okay, and now we'll go ahead and put the cap back on on our 4 flat wiring harness and put it in the storage compartment, and with that, that will conclude our installation of the Tow Ready T1 Wiring Harness with the 4-Pole Flat Trailer Connector, part number 118461 on our 2000 Subaru Outback Wagon. .
