Question:
I have a 2025 Hyandai Santa Cruz Limited. Do you have a 7 way wiring connection that I can use on my car to connect to a travel trailer?

Expert Reply:
We sure do Scott! To add a 7-way to your 2025 Hyundai Santa Cruz, I recommend the Universal Installation Kit for Trailer Brake Controller item # ETBC7.
The item # ETBC7 kit includes a pre-wired 7- and 4-way trailer connector that mounts at the rear of your Santa Cruz with an included bracket. Also included are all of the circuit breakers and wires you'll need to complete the installation. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it. If you don't have a 4-way connector you can add one with the Curt item # C93DQ. It plugs in behind your tail lights.
To install the item # ETBC7 kit you'll connect the blue wire to the blue wire on the brake controller, connect the black wire to the positive post on your Hyundai's battery, the white wire to a suitable ground, and the yellow wire to the reverse 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.
I've linked a couple of installation videos and also attached a wiring diagram so you can see how to get these parts installed.
What kind of travel trailer do you have and would you also like a recommendation on a brake controller?
