Default Tach output for 04' Silverado

Can someone tell me what the tach output wire for an 04' silverado SS is?

I have been searching for over an hour and all I get are posts about F-bodies and window tinting and other such nonsense

thanks for the help!

Pretty sure it is pin#10 on the Red Plug. I dont want to go out and take the PCM out right now, but if the wire is white.....that is it.

I was figuring it might be ten if it was white. Thanks for the information.
