How to Install a Trailer Wiring Harness on a 2010 Subaru Outback

Alright, today on this 2010 Subaru Outback, we are going to install part number 118467 from Tow Ready. OK, the first thing that we need to do is get in the back of the vehicle. We need to open the trunk area. Alright, we will take out the floor panels. Start with this cover here. Now we have to take out the Styrofoam parts too. And we are going to work our way down to the sheet metal here. And then we are going to remove this piece of Styrofoam here, There are a couple of little plastic rivets. 0:51

Now our wire harness is probably going to be tucked in underneath this plastic right here, or this felt. It is kind of hard to get to so we are actually going to just take our panel loose. We are going to start off with the threshold here. We are going to pop it off an lift it way back. Alright, we will have to take out these tie-down loops right here. There is a little plastic cover on the inside. And just pop it off. And there is a bolt inside here. Now we will lift this up, out of our way. OK and we should be able to reach up underneath here. And you can pull it out and there is our connection. 1:36

Next we will take our wire harness. We are just going to plug it together, just like this. Then we are going to take our wires and our converter box and we are going to tuck it underneath the covering here. And actually we are going to attach it to the sheet metal underneath here, using an adhesive that is provided. Alright, we will extend our 4-pole cable out. And at this point, we will start reassembling our interior. Alright, when we put this component back in, we want to keep our wire harness above it so we can get to it easier. 2:11

Alright, at this point, I will show you how to use the wire harness. All you have to do is pull this center section up. Pull the harness out a little bit. And then just let it sit back down. Then you shut the hatch on the wire because the weatherstrip is thick enough to where it will not get damaged when you close the door on it. And the main thing is to just keep it away from the center latch. And pull out as needed to your trailer. When you are not using it, keep it in the storage compartment here, or in the well. And that way it is not sitting out all of the time, getting corroded, when you are not using it. 2:45

OK, the last thing that we need to do is go ahead and test our wiring. We are going to use a light tester before we try it on a trailer. So we will hook our ground to our ground lead right here. Ground will be white. First off we will start with our running lights and that will be the brown wire. OK, that is good. Then we will try our left turn which will be yellow. And then green will be our right turn. And brakes will be yellow and green. Alright, we know our harness is good. We can go ahead and try it on a trailer now. Alright, and with that, that will finish our install of part number 118467 from Tow Ready.
