HI LEW BOTH of the wires are the same colour . There for the wires are ethere hot with power or no power cold for ground. THE switch only closes the ciruit. its the same as if you put the two wires togethere. my guess is they are cold ground wires and are working a relay switch back under the dash. if you put power to them you will damage the relay.. so don't put power to them. if you put power to a ground relay it will weld its self closed and say closed some times if the power is to much. There is no doubt that the switch is just closeing the ciruit. BECAUSE THE WIRES ARE THE SAME COLOUR. I hope this will help you out SIR.
