volt meter gauge install

[jpwesly031]

67 firebird... what 12v source in the fusebox under the dash can i use for a volt meter gauge? i dont want to hack into anything.

also what factory color wire is recommended to splice into for lights for aftermarket gauges.

Any power can be used for a voltmeter. Use IGN or ACC on the fuse box, so it's not constantly on. Also there should be a spot marked DASH or LAMPS, to power the gauge lights.
