His setup is different. Speedometer cables were eliminated sometime around 1988 or so. On your car and my 93, the speed sensor generates a digital signal via Hall effect pulses, which is converted to an analog signal for our analog gauges, at the cluster. And so ours are not 'purely digital' because the end display is analog, as is the signal. His is purely digital, he has a digital dash. However, the factory manuals show a speedometer cable from transaxle to cruise servo, and another cable from servo to dash - regardless of whether it's automatic or manual, and it doesn't distinguish between analog and digital dashes. So that's why I wonder if he as a car that had an analog cluster, and someone wired a digital cluster in, with homemade wiring.
