Thank you for the quick response! I've heard there are constant voltage regulators that snap into a 9v battery terminal? I can't seem to find that on my 69 on the cluster. Is it just for the older years? The black/green wire near the ingition switch is the 5 volt pulsed power? I have a 12 volt ignition wiring already spliced for the radio, I was going to use that to power my 12 to 5v constant converter.
