Custom Wiring Harness, 4-Way Flat Output fits Select Toyota Corolla Cross

With a towed-vehicle RV harness installed, hitching up your vehicle behind your RV is fast and easy. Simply plug the provided 4-way flat connector from the front of the vehicle into the RV's 4-way flat socket. The RV harness uses the vehicle's existing tail lights, turn signals and brake lights, eliminating the need to purchase additional lighting. The vehicle's lights are able to operate in conjunction with your RV's lights, signaling other drivers and functioning just like a standard trailer in tow.
