P1 Speedometer test- Help pls

Hi All!
I wanted to check out our P1 Speedometer on our 1996 gtv spider using the metal file trick that i read about on this forum. I just needed to know which Sensor wire/wires from the speedometer connects to the file and car battery (the car battery is the right power source isnt it?). I assume the metal file and speedo sensor wires are connected to the car Battery in series?

The Speedo sensor has three wires: One is blue, Center wire is yellow w/a dark color (black?) and third wire is brown or very faded red??. Please identify which wire connects to what, and please state (-) or (+) connection. Thank You!
