If you engine is 4.3 liter it is white. Other size engines may be purple. Does you GMC have a factory tachometer in the gauge cluster? If so, tap behind the cluster. Also you can go to anyone of the fuel injectors or coils. It the uncommon wire color

TACH SIGNAL

White

At VCM module

The VCM is located on the left side of the engine compartment. The WHITE tach wire is located in the bottom of the 2 wire harnesses. The VSS is in the same location.
