Trying to get this MSD window sitch in and can't figure out which one it is. Someone know?

 

Its the white #10 wire from the PCM on the Y2K vettes.

Well I see three white wires. Two plain white and one white with a black stripe. Can't really tell how to find #30. Thanks for the reply.

 

Try this, its the #10 wire on the RED connector.

Sorry guys but those are Fbody schematics and do not correspond with my PCM in the vette. Anyone else know?

 

Hate to bring back a thread from the dead, but what was the answer to this question? I tried searching.

 

Go to corvetteforum.com in the tech section as they just had a thread on this or do a search there. If you are in the right wire harness (under drivers dash) you can test the three white wires because two are for alarm stuff and not active when running. Just use an ohm meter to see which one is live and bingo. Also, thread said the tach wire was also a off white compared to the other two white ones. Go to thread though incase I forgot something.

 

Friend of mine that was looking finally found it. Sprayed it earlier

Thanks for the help though.
