Need help connecting RT-622 trailer to my F3-S,
I have a 2016 F3-S and a 2010 RT-622 trailer. the new hitch harness is a 4 wire connector and the trailer is 6 wire (I think).... I do not understand how the wiring actually works. The hitch control box has 6 wires going in (ground, tail, left turn, brake, right turn and battery) and 4 wires coming out (ground,tail/mark,left turn,right turn). There is no wire out of the control box for the brake - what activates the brake?....
Thanks guys, hope you can help...
