Tips on Routing Trailer Wiring Harness Power Wire on a 2014 Toyota RAV4

Question:

I am concerned about running the hot lead to the car battery. How much work does this involve? The rest of the wiring harness installation seems pretty straight forward Ive done it before on my 2004 Toyota Highlander.

Running the power wire to the battery when installing Curt trailer wiring harness # C56350 on your 2014 Toyota RAV4 is not all that difficult, it can just take some time depending on how you want to route the wire. How much time it takes varies.

There are a few different methods to route the wire. I have included a link to our help article that covers tips on routing the power wire. It must be attached to the battery, no other power source will do. This is because the harness has only been tested with the battery connection and if not connected to the battery the trailer wiring is not isolated from the vehicle wiring as much as it could be.
