I would like to install an Audiovox CCS-100 electronic cruise control in my 1988 924s. The instructions want to know if this vehicle has a "vehicle speed sensor" and, is so, the number of "pulses per mile" from this sensor. I don't have to connect to this sensor, but if I don't connect to it, I will have to attach magnets to the drive shaft. Does anyone know if the 1988 924s has a "vehicle speed sensor" and the "pulses per mile" and where to connect to this sensor?

Thanks
