A few conversion wiring questions!
Does the PCM control whether the AC Relay trigger has a ground, or does it give the trigger 12v?
Does the PCM Speedometer OUTPUT put out a pulse for aftermarket electric speedometers to pick up? That would make speedometer alterations a breeze.
The PCM puts out a 4000 pulse per mile square wave DC signal to the speedo. Some aftermarket speedos will accept that, others need the sine wave AC signal direct from the VSS.
