as im not a 90s tahoe guru with everything memorized as i mentioned in my other post about selling my tahoe. i needed some information for wiring for the ignition system on my ex 97 tahoe. above link was a good help for knowing what wires on the icm and coil are for and figured id post it up if anyone ran into a similar issue.
