Can someone tell me which wire going into the coil pack (3 coils together) is considered the negative coil wire? There are 14 wires in the plug. I am trying to make a connection and one is 12V, 1V, some register -mV and others +mV on my multimeter. With a single coil, there used to be a positive and negative side. I need the "negative coil wire".

You didn't say but this is the 3.8 setup, and close up of the coils and ignition module.

You said "Tack" is negative. Did you mean "Tach"? I see one labeled "I/P Tach" which is the white E wire in the 8 way harness. Please let me know. Thanks!
