Your tach should work OK with a wire directly from the MSD tach output to the signal side (not the green-wire side) of the tachometer.

Yes, I was trying to maintain 2,200 RPM for 30 min total with the break in
oil before letting it idle for the first time.
Should I leave the orange wire at ERA harness #40 connected to the white wire of the MSD, or disconnect and just have the wire from the MSD tach output going directly to the signal side of the tach?
