Does anyone know which one of these is the tach signal wire? I'd heard it may be a white one but wanted to check here first. Installing a shift light. (2002 Z06) This is the group of wires that plug into the back of the instrument cluster. Thanks.

If I remember right, you can probe each white wire with a test light (grounded of course) and when the tach needle jumps, you know you found the right one.
Tach signal wire color....?
