How To Install a Trailer Wiring Harness to a 2011 Toyota RAV4

Question:

I am used to wiring directly into the existing wires with the quick connects but I have been told I can not do this with my 2011 toyota. Right or wrong? Thank you.

You will not want to connect your trailer wiring directly to the wiring harness of your 2011 Toyota RAV4. You will need to isolate the trailer wiring from the vehicles sensitive circuitry, so it does not put a strain on the system and cause your vehicles wiring harness to be overloaded and fail.

I would recommend to use the Tow Ready T-One Wiring Harness, part # 118412. This wiring harness will plug into connectors located behind the vehicles tail lights and comes with a powered Modulite converter that draws power for the trailer lights from a separate power wire that is connected directly to the vehicles battery.

I am including a link to the installation instructions on the Tow Ready wiring harness and a video link of the harness being installed on a 2010 Toyota RAV4.

Hi there, I have a 2010 Toyota vanguard and I want to install a trailor wiring kit into my car harness. What kit do I need?

The Tekonsha # 118412 mentioned above may work for your Vanguard, since it's the overseas version of the RAV4, but it's not something I can confirm. All of our products are only tested and rated for US marketed vehicles.
