1985 911 Carrera Speedometer Signal
I am looking for information on the signal sent to the speedometer from the unit under the rear floor. I want to log data and need to know the frequency (Hz) sent via the wire to trigger the speedometer.
Does anyone know the specs of this wire signal? Also, it looks like two wires are on the sending unit, which one do I tap? Thanks, Craig 1985 911 Carrera 3.5L NA Twinplug, GT2 cams, 300hp |
