i have a 99 dx and the stupid gauge cluster doesnt have a tach in it so i think im gonna buy an si gauge cluster. ok so here it is since the dx doesnt have a tach should there be an adapter thing to plug into an si gauge??? ok i have the 2 big blue adapter things that plug into the gauge cluster and i have a small yellow one that does to and i also have a small orange one that is taped out of the way of all the others so is that the tach adpater one or what is it thanks!!
