The hour meter in my tach has stopped working. The tach works fine so will install a separate hour meter near the Nav Station. I don't see engine hour meter listed in my ABYC DC wiring color code chart. Would it be orange for "Accessory Feed", violet/purple for "Ignition", or something else? Thanks for the help.

Orange would be an accessory fed from the distribution panel, typically.  Purple is " switched power " (like the alt field excite circuit and engine panel feed to the gauges.) I'd go purple (presumably powered by the field excite or fuel pump circuit ( which are redundant)?
Twenty years from now you'll be more disappointed by the things you didn't do, than by the ones you did.
