$(document).on('knack-view-render.view_XX', function(event, view) {
  var customer = document.querySelector("select#view_XX-field_YY.select");   // view_XX is your Form view. field_YY is your connection (Customer) field
  function get_address(id, callback){
  let headers = {'X-Knack-Application-Id': 'Your Application ID', 'X-Knack-REST-API-Key': 'knack', 'Authorization': Knack.getUserToken()};
  let api_url = 'https://api.knack.com/v1/pages/scene_A/views/view_B/records/' + id;  // This should point to a table view in your app where at least the one of the columns is for field_YY and the view should 'technically' be available to the logged-in user  
  $.ajax({
    url: api_url,
    type: 'GET',
    headers: headers,
    success: function(response) {
      callback(response);
    }
  })
}
function put_address(data){
  if(data.field_ZZ !== "" && data.field_ZZ !== undefined){   // field_ZZ is your Address field from the Customer record
  document.querySelector("#kn-input-field_WW #street").value = data.field_ZZ_raw.street;  // field_WW is the Address field in your Order form
  document.querySelector("#kn-input-field_WW #street2").value = data.field_ZZ_raw.street2;
  document.querySelector("#kn-input-field_WW #city").value = data.field_ZZ_raw.city;
  document.querySelector("#kn-input-field_WW #state").value = data.field_ZZ_raw.state;
  document.querySelector("#kn-input-field_WW #zip").value = data.field_ZZ_raw.zip;
} else {
  alert("No address found! ");
  console.error("No address found! ");
}
}
function clear_address(){
  document.querySelector("#kn-input-field_WW #street").value = "";
  document.querySelector("#kn-input-field_WW #street2").value = "";
  document.querySelector("#kn-input-field_WW #city").value = "";
  document.querySelector("#kn-input-field_WW #state").value = "";
  document.querySelector("#kn-input-field_WW #zip").value = "";
}
$("select#view_XX-field_YY.select").on('change', () => {
  if(customer.value === "" || customer.value === undefined){
    clear_address();
    console.log("No Customer selected!");
  } else {
    get_address(customer.value, put_address);
  }
});


});

Hi Mark - default field values not enough?

I think you might have more complex requirements that needs further explanation?
