Ok.. lol.. If thats what its for :P .. Its just, my Lumina has a Tach. and there is no Orange wire on its plug.. But if its something to do with the Digital part of the equation, then Ill run it there! THanks!

Does the Bi-directional Serial Data Link between Cluster & ECM have ANYTHING to do with the operation of the Tach.? It is orange in color on pin location C13 for the Cutlass..
