    Are you looking for a stock or aftermarket tach?

    I don't know what year you have, but the wiring of most aftermarket tachs is similar. +12V constant (batt), switched +12V, ground and a tach signal. The tach signal terminal is found on an HEI distributor on the cap itself (will be marked "tach") or on the ECM somewhere, seeing that you have a '91 (just looked at the profile), that could be a possibility, too. I'd check out the distributor first, though, before the kick panels start flying. Hope that helps, as I'm assuming that's the info your looking for?
