Aftermarket Electric Speedometer
For those of you that have added a speedometer controlled by your ECM
What brand of speedo are you using ? What is the signal that is produced by the ECM? Does the transmission VSS make a difference if it is a 4L60E or a 4L80E or is the "magic" controlled by the ECM and not the VSS? What Pin or Pins control the speedometer and what is the signal that is transmitted to the speedometer?
