Locate the PCM in the engine compartment. PCM is right beside the battery.

Tach wire is WHITE.

DEI Info. Note

CHEVROLET, AVALANCHE, 2004, Tachometer

The PCM (Powertrain Control Module) is in the left front of the engine compartment to the left of the fan shroud. The tach wire is in the green plug, pin 10.

For tach can also go to any of the ignition coils or injectors and use the wire that is NOT pink, black, or brown.

EACH COIL HAS FOUR WIRES USE UNCOMMON WIRE DO NOT USE THE BLACK, BROWN, OR PINK. USE THE WIRE THAT IS NOT THE COLOR THAT IS MENTIONED
