I just picked up a used gtech for fun. It's got the sequential shift light gizmo on it that looks pretty cool. I also have a Raptor shift light that I havn't installed yet. Should I sell the Raptor? Does anyone know how accurate the GTech shift lights are? Thanks.

 

The g-tech only has the power wire going into the cigarrette lighter right?

How accurate cold that be compared to something that taps directly into the tach signal?
