Tach hook up

[VernLee]

there's two white wires coming from the coil pack, the first one
is closest to the fire wall, the next one is about five wires in, which
one is the tach wire, and where does it go to under the dash,
I have been trying to figure this out for weeks, HELP !!!!!!!!!!!!

You get the tach signal off of the loose green connector hanging behind the alternator. It'll have two wires going into it.
