Question:

On the towed vehicle can I use a six pin female plug and ground the white wire back through the seven pin rv connector to the rv ground? My concern is Ford said remove the neg battery wire to tow the 2014 Focus . Will grounding the white wire to the Focus cause a ground for the towed car?, If so this could possible burn up the auto trans or other components? 2014 SK-35 Thor to 2014 Ford Focus Auto Trans , Blue Ox Frame Brace , Blue Ox Alpha Tow Bar , Blue Ox 7 to 6 pin connector cable for car to rv, RVI 2 Brake and Hopkins HM 56007 Tail light Kit

Expert Reply:

The white ground wire on a flat-towing harness like # HM56007 or # HM56008 will attach to the towed vehicle's frame or battery negative terminal. This will not have any effect on your Focus' transmission nor will it cause any issues with battery drain. When connected in this manner the ground will still eventually route back to the RV but you do not have to wire it as you describe.

Do be sure to follow all of the steps outlined in your Focus owner's manuals for making the car ready for flat towing. This IS important to the transmission to ensure it is not damaged from flat towing.
