Answer
This should point you in the correct direction:

Tach  Signal:
GRAY & DARK BLUE (2.4L)
AT COIL PACK ON TOP OF VALVE COVER

*Each Wire Listed Above Is A 2 Cylinder Signal.
3.0L Tach Wire Is GRAY/RED At Powertrain Control Module (PCM).

3.3L & 3.8L Tach Wire Is GRAY/RED, DARK BLUE/TAN And
RED/YELLOW At PCM (Each Wire Is A 2 Cylinder Signal).

Good hunting!
