Look in illistrated upgrades at the shift light install,
I think the same wire on the PCM plug (which is (I think) the #4 coil wire) would work.

If you are using the MSD window switch, you do not use the tach leads. You pick up any one of the coil driver leads. On a Gen 2 is in PCM C3. Use the search function, I displayed the location/pics of an installation for a shift light, it does use the tach leads which can be picked up in C1.
