I cannot remember exactly how long the cable was but I ran it from the license plate (obviously) to the rear of the avicD1 in the Sequoia. All three wires (video, power, and ground) are run at the same time. You could contact Boyo directly through email and they should respond within a day or so. That will give you the best answer. I emailed them asking about their product and received a response within 24 hours.
