2003 coil ground wire?

I am looking for a diagram for a 2003 4.3 v6. I am looking where the ground wires are terminated at for the coil and ICM. AQny help will work.

THANKS!

Terminal "C" at the ignition control module, (Black with white trace wire) grounds to the rear of the left cylinder head.

The PCM supplies a pulsed ground to the ignition control module, which in turn fires the ignition coil.

Is there is no spark while cranking?
