FJO window switch, what do you set the tach signal to?
I am putting in my FJO window switch and want to make sure I have the tach input set right. Do you use a 4 cylinder engine as the input, like most other window switches?

It depends on how you wired it. The easiest thing to do is to set it to 4 cyl and have someone hold 2,000 RPMs and use the view RPM funtion and watch it to make sure it matches the cars RPM. If they match, then your done.
