    I have a 97 mustang gt that I just started wiring my NX kit up. I have a summit racing digital rpm window switch to activate/deactivate at set Rpm's. So what I need help with is where should I get tach signal from? Also do I need to hook up the activation wire from the rpm switch before my fuel pressure safety switch? Any help would be greatly appreciated.
