2000 impala where is tach wire?

I dont have a wiring diagram for my car, but I was wondering where is the tach signal wire on my 2000 chevy impala. It has the 3.8 V6 engine. I want to install a tachometer on my dash... any help would be appreciated....!!!!!

If it's a aftermarket tach you should be able to go to the coil for it to work just like old school cars.JMO If you were changing out the entire cluster then you go to the PCM.

I believe that year engine is a coil pack with crank sensor = no distributor.

I wonder how that works for an aftermarket tach?
