Tach Adapter, Help

[seanwr400]

I am trying to install a shift light and it reqires a tach adapter. I am installing it in a 03 cobra. What I need to know is where to tap into the 12 volt feed wire for the coils. Any idea where I can find a wiring diagram for the car online? I have the car tore apat now and would hate to have to put it back together just to make a run to get a book. Thanks!!

Did you get a wiring diagram already?

Do you have a shift light with RPM switch (tach adapter) built in or do you need to purchase a tach adapter?

The signal for the RPM switch can be grabbed in/at the factory tach wires (not sure of color). For the power just wire it to a switched 12V power source, just ground it first.
