Default Tachometer Wire? ASAP???
I have an Auto Gage Tach and I have it all wired up but I have no Idea where to run the tach wire... the one that receives the signal from the engine... someone told me it was the 10th white wire on the pcm.... but thats a different car...

Oh and if its on the PCM where and how do I get to it?!

It was the #10 white wire on my 2002 Z28. I ran the wire under the dash and out the grommet near the glove box to the PCM.

I have the same car, how do I locate this #10 white wire. My PCM has no numbers the connectors all have letters.
