Does Installing Trailer Wiring on 2017 Toyota RAV4 Require Disconnecting Battery

Question:

Hello, I purchased a Curt Hitch for my 2017 Rav 4. I also purchased the T 0ne wiring harness. The instructions state that I have to remove the negative wire from my batttery. I dont see that on your video. Can you tell me which is correct? If I remove a wire from my battery, will it affect the electronics on the car?

The Curt trailer wiring harness part # C56350 that you bought for your 2017 Toyota RAV4 does require removing the negative battery terminal. This is a safety precaution that is recommended almost anytime you are working on something electrical for a vehicle.

We don't have an install video for this harness though so I am not sure where you saw that it's not a required step.
