Hey guys, I hear the factory tach is horribly innacurate.. so I bought an Autometer 3 7/8" sport comp tach. I'm going to install it on the steering column, covering up the factory tach. My question is, power and ground I can deal with, but where do I get the signal from? Thanks guys!

Run the tach wire to the PCM, I think it's #15 on the red terminal, open the PCM covers and you'll see these little #'s on the connections, I ran the wire behind my dash all the way to the passenger side and there's this little grommet behind the kick panel that will allow you access to the engine bay, run the wire through there and up towards the pcm, just splice it into the wire on connection #15... good luck!
