my truck's got a factory tach dash. i put a painless system in, which has a wire for the tach signal... and it goes from the guage, through the fuse box to the engine compartment, and i hit the distributor in the harness as i went on by...

no idea where GM put their grommet hole - i have the factory tach harness, but couldn't see where it went through in firewall... there is a small hole by my distributor, but I used it for my oil pressure guage...

hope this helps...
