Long story... but here's what I'm trying to do..
My VSS is a sine wave output.   I'm trying to split the VSS high-side signal to run both the ECM (which requires a sine wave) and an Autometer speedometer.
When I tap the Autometer speedometer into the VSS high side, the speedometer works great. But the ECM reads zero at any speed.   Almost seems like the speedometer is "hogging" the signal.
Thoughts?
The speedometer can output a 0-5V square wave signal, but the ECM can't use it.
