For most RV's using the power pin in your RV's trailer connection will work, but in certain cases the power supplied by that power pin is not consistant. It fluctuates and causes an error in the LSL charging unit and it will not charge. You will also want to check the voltage of the trailer pin connection to make sure it remains consistant.
For this reason LSL provides a full harness and recommends its use for trouble free operation.
