Hey Josh, congrats on the new camper! To install a 7-way connector on your 2015 Toyota Venza you'll first need to have a 4-way connector. I have listed the parts you'll need below:

4-Way Connector - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # C56079. This custom-fit T-connector plugs into your Venza's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. It will give you a 4-way connector capable of controlling your trailer's lighting functions.

7-Way Connector - The second harness you will need is the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your vehicle with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it.

You will then connect the blue wire to the blue wire on the brake controller, connect the black wire to the positive post on your Toyota's battery, the white wire to a suitable ground, and the yellow wire to the accessory circuit. This will provide you with the ability to control your trailer's brakes and also provide you with a 12v power wire for you trailer's battery. This kit includes all the wiring, connectors, and circuit breakers you'll need.

Do you already have a brake controller?

Hey Josh, how did things go getting the 7-way connector and brake controller set up on your Venza? Your experience could point others in the right direction when wiring their own camper trailers.
