Electronic Tachometer Conversion
I purchased a Electric tachometer conversion kit for my 73 but it did not come with instructions.
I have worked out how to set the needle to zero, but not sure about the settings for the #1 & #2 toggle
switches on the back.
At the moment #1 is in the off position and #2 is in the on position.
Need to get these right before refiting

Need more info.
Who made the conversion? Can you scan and post pics of setup. Maybe a part #?
I suspect that this is an aftermarket setup vice a '75-up Corvette tach board. So, it probably has the ability to work with multiple engines (4, 6, or 8 cylinders).

Best info I could find:
Looks like the switches toggle between 4 and 8 cylinder mode. Wilcox Corvette carries these so maybe reach out to them for help, especially since you are halfway around the world. They could probably scan an instruction sheet and send it to you.

The kits are pretty basic with three wires, black is ground, red hot and green is the input. Once installed in the face or housing you can run a power wire to it, run a ground wire to it and then get your signal to the green from your source. If the tach is not reading correctly and zeroed out, tweak the potentiometer on the board to dial it in (it's the square blue box with the white slotted adjustment in it). If you don't have a signal generator then you can test it by putting the old generic dwell/tach meter on it.
