Differences Between Available Trailer Wiring Harnesses for 2012 Ford Explorer
Updated 02/27/2012 | Published 02/24/2012
Question:
I like this setup because it looks easiest, but ford seems to recomend using a setup with a converter, is this necessary, what are risks of not having one?

You can use the Tow Ready # 118540 with no problems, as long as your Explorer is equipped with the connector shown in the photo I provided. The signals used at this connection point are already converted, so no additional converter is needed. This connection is circuit protected by existing fuses, so there is no risk involved with using this harness.
The Curt harness that uses the converter attaches directly behind the tail lights, at which point the signals are not converted, which is why the converter is needed. Most likely, Tow Ready has licensed the OEM connectors from Ford, while Curt has not.
I have linked you to the install instructions for the Tow Ready harness, as well as an install video that you might find helpful.
