1. A neural stimulation method comprising: using at least one electrode lead having a proximal end and a distal end and comprising a plurality of spaced apart electrodes carried by the distal end, positioning the distal end of the at least one electrode lead so that the electrodes are adjacent at least one nerve in a patient; using a subcutaneous lead connector plug comprising a housing electrically connected to the proximal end of the at least one electrode lead and defining at least one lead connection port and at least one anchor point carried by the housing, positioning the housing along with the proximal end of the at least one electrode lead inside the patient beneath the patient's skin; connecting the at least one anchor point to tissue beneath the patient's skin; using a first generator lead having a distal end and a proximal end, plugging the distal end of the first generator lead into the at least one lead connector port to electrically connect the distal end of the second lead with the at least one lead connector port; connecting the proximal end of the first generator lead to an external neural stimulation generator outside of the patient's body, and operating the first neural stimulation generator during a trial period to provide electrical stimulation to the at least one nerve via the plurality of electrodes; and unplugging the distal end of the first generator lead from the at least one lead connector port after the trial period while leaving the at least one electrode lead and the subcutaneous lead connector plug inside the patient.
