I need help with the 2002 LS1 PCM PIN Assignment? I am trying to install a shift light from raptorperformance.com but need help with the pcm pin assignment for a 2002 Camaro SS. I know that the #10 white wire is for the rpm signal, but I need to know if there is a wire I can use as a 12 volt switched for the power wire also. Anyone know where I can find a layout/picture of the pin assignment for the 2002 LS1. let me know, thanks

Used to be a PCM pins set of tables on LS1.com,
it went away. Looks like it traveled with the folks
who went to LS2.com and it's linked in that site's
tuning section.
PCM C1 pin 19 (pink) is IGN. I believe in general
if you find a pink wire it's IGN (switched 12V).
Easy to push a pin through the insulation and
check, if you find it in a convenient place but
can't trace it back physically.
