Is The Power Wire Required When Installing The Curt T-Connector Vehicle Wiring Harness # C56350?

Question:

Is the wire to the battery necessary? I have people saying that’s only for pulling a trailer with an electric brake. So what is the correct answer. Thanks.

The Curt T-Connector Vehicle Wiring Harness # C56350 for your 2014 Toyota RAV4 uses the battery connection to send power to the trailer lights directly off the battery. Older vehicles where the manufacturer put in larger wire than what the tail lights needed prevented the need for these powered modules like are required on todays vehicles with thin wires only providing enough power for the tail lights. This is where a lot of confusion rests as typically a power wire was only ran for a trailer charge line which is required for trailers having electric brakes.
