Just to let you know…. I took a test drive yesterday and everything works on the instrument panel….all gauges, lights, turn signals, and speedometer. I don’t recall if I said it earlier but I resorted to replacing the voltage limiter with an external 5V power supply. All is good for now - thanks again for your help.
I still need to replace some wires under the hood that are spliced in multiple places due to rodent damage that happened many years ago - but everything works in spite of the wire-nut splices.
