Not sure if this is what you're after, but if you are trying to locate the tach signal wire on the PCM, this may help (from InstallUniversity.com) :

1999, 2000, 2001, and 2002 model F-Body's should locate the number ten (10) pin. The wire should be white in color. 1998 model F-Body's should locate the number 35 pin (in the upper cover) and the wire should be white in color.

For the complete writeup with pics, visit the site and look under shift light install. Hope this helps...
