72 Fj40 speedometer wire connections (1 Viewer)

Can anyone identify what the two wires are looking acted above the odometer and where these two wires go (black and white), cannot find them on my wiring diagrams?

Those two wires are for the "Speed Sensor" and go to the Spark Controller (Emissions computer). I have attached a schematic that shows this wiring. It's in the little box at the bottom #35 = Speed Sensor, #36 = Spark Computer, # 37 = Thermo Sensor, and #38 = Vacuum switching valve.
