I have an old kiln I have no idea of manufacturer but my elements do not run on top of each other in a straight line they run side by side so it goes in the kiln and comes back out in the kiln on the same row all the way down and I cannot figure out how to wire it up and I cannot find any information on it and the plug I have only has NL 1 2 3 on it how do I hook the elements up to the switch I can only find information on whether in a straight line up and down mine aren't like that
