Sine Wave Generators:
Vehicle speed sensors that generate A/C or sine waveforms are two wires sensors. If your vehicle has an aftermarket two wire speed sensor then connect this wire to the same wire ran to either your fuel injection computer or speedometer. If your vehicle has a factory VSS generator you will need to identify which of the two wires is the high side wire. OEM schematics usually show this as VSS High wires. If you are having issues identifying which wire to connect to here call our tech line for assistance.
