I need help or information.

i currently have a o5 focus and im trying to install a tachometer in my car. The only problem is the tach won't go more then 2000 rpms. Do i need a tach adapter ? plz respond or let me know if you know what to do thanks !!!!:naughty:

If you have installed an aftermarket tach you need to set the no. of cylinders on the back of it. They are designed to fit 4, 6, and 8 cylinders.

I know that !!
