3 gauge dash to 7 gauge dash conversion?

I have a 1967 c10 pickup with a 3 gauge OEM dash and i would like to convert it to a 7 gauge OEM dash. FYI. I have a 1990 chevy TBI engine. The tach is a HEI with a remote coil. so wiring the tach is a issue. Any info would help. Thanks!

Just wire your tach to the tach terminal of the HEI coil.
