Instructions for Installing a T-One Wiring Harness # 118449 on a 2011 Toyota Higlander


I have a 2011 Toyota Highlander. Do you have instructions on how to get to the 4pin connector with 3rd seating?


Expert Reply:

The connector you are looking for is located over on the driver side behind the storage panel in the back of your Highlander near the driver side blinker. You are going to need to remove the rear cargo floor and fold up the forward one and also the driver side cover. To get the storage box out the screws at the bottom as well as the three push fasteners on the inboard side will need to be removed.

Once you have removed the storage box you should look on the back side of the exposed area near the tail lights for a small 4 pin connector, this will be what you plug the harness from the # 118449 into.

I attached a video on how to install the T-One Vehicle Wiring Harness with 4 Pole Trailer Connector, part # 118449, on a 2010 Toyota Highlander below for you to check out. I also attached installation instructions for this product below.

The harness should be in the same area of your Highlander regardless if it has the third row seat or not, they only thing that might be different is how you access that area. There may be different panels that need to be removed than the ones mentioned above, but either way you will still need to get to the same area.
