tach wirring

can any help me with this problem. I have a 2000 camaro and I just put an aftermarket tach in it and dont know where to wire the green tach signal wire into. thanks for anyones help.

1) Do a search, this has been addressed ad-nosium for a simple install.

2) If you are hooking up 2 or 3 tach feeds to the PCM you'll need to get a little more elaborate due to noise in the signal (don't worry about the PCM though, it's just an output wire and won't after engine controls). Again, i know this has also been addressed before.

On the lower pcm, the #10 output wire, which is WHITE in color

V6 or V8? That will determine which forum this belongs in.
