What do you mean by "T". On the back of the instrument cluster????

im confused there...... well wut kind of car does he have right now?.if he has a honda there is usually a blue wire at the back of the instrument cluster that is for rmp..so all you have to do is cut it and crimp it to the wire for your tach and the tach should be good to go.
