2002 honda civic tach help

i have a 2002 civic lx and i dont know were to find the tach output wire for my car. if anyone can help it would be appreciated...

Don't you already have a tachometer with the LX version? Are you trying to install a monster tach or something? Try JDMfan.com (they may only be 99-00 civic oriented from what I remember though) or do a google search for specific wiring diagrams.
