The witres are red, black, and white. They go into the floor. If you look closely, one spliced white wire is disconnected.

87 Escaper. The previous owner (dont have contact info) installed a gas only manual light hot water heater. However there is a lighted switch (the light still comes on) near the rear exit just below the oven. What does or did this switch do? Is it still in play for something?  Thanks.
