tach install?
 

has anyone done a tach install on a 05 mustang because it is said to be very different than a 94 and down, or can anyone guide me to a wiring diagram to do so thank you

RE: tach install?
 

whats wrong with your tach? If you were doing it for a shift light then it might be easier to add in the shift light only. First though you would need a tach adapter. MSD sell one, they go for about $50. The tach adapter changes the waves sence DIS units use a crank angle sensor to fire the coils. I installed one in the power point by the traction control button. looks good. Bright enough during the day too. It also makes a hole free dash.
