In the drawing attached, look at the Main Switch. It shows a R and Br wire going to a plug. The plug is a four pronged plug. There are two other wires on here that go to the switch (B and B with R tracer). What are they for? They're not shown on the diagram or Hyundai used a different standard in their electrical drawings that I'm not used to seeing. There is also two other wires on the switch that go to a separate plug which is not plugged in to anything. What is it for?
