How to Power Trailer Observation Camera From 2018 Toyota Highlander


I would like to add a wireless camera to the back of my 5x10 enclosed trailer for better rear viewing. Currently I have the basic 4-pin connector from my 2018 Toyota Highlander Hybrid to the trailer. What are some good options for getting +12V to the trailer for the camera?


Expert Reply:

It really power your observation camera from your 2018 Toyota Highlander, the first thing you will need is a 7-way with a 12 volt charge, so start by installing the 7-Way RV Upgrade Kit # ETBC7L, which is generally used for wireless brake controller compatibility but is perfect for what you're looking to do.

You'll also need the Bargman 7-Pole Round Connector w/ Hardware - Trailer End # 54-67-525 for your trailer and can cap off the unused wires on both of the 7-way connectors and you can tap your camera's system directly into the 7-way, or the better method is using an accessory battery, for which you'd need a battery box like # 329-HM318BKS (depending on your batteries) and wire it directly to that, charging the battery with 12-Volt Universal Battery Charger # CTEK56353 when needed.

I have added a link to a video review of the 7-way kit as well as a link to our selection of battery boxes and cameras for you to take a look at.
