Charge Line Cost

Thanks again for the additional information. We are almost sure we are going to purchase the Ford C-Max (2013)if we can find what we want. It would be ideal if everything could come out of one cord to supply all of the requirements for towing. I think I read in prior posts that someone was using a magnetic light bar for brake lights and signals to avoid messing up the wiring in the car. We would of course still add the charge line for the 12 volt power in the car.
