I'm going to add Pierre's F3/F3S hitch to my F3. His harness comes with a 4 pin flat plug but we have an RT-622 trailer. I haven't been able to find an adapter that will go from 4-pin flat to 4-pin square. Lamont's adapter is the other way around (OEM harness to non-BRP trailer.) Anyone have a lead on the correct adapter?
