Not completely sure on the gt-4, but on the 5sfe it is a gray wire and to find it you need to go to the igniter on the rear driver's side of the engine compartment and look in a connector in that area. If you think you've found it, just test it with a multimeter on AC mode

There is a blue plug on the back of the instrument cluster. It is pin # 9, wire is gray.
(found that but will double check) -------------------- |

I wouldn't want anything to go wrong with the RPM readings. Correct me if I'm wrong guys, but I believe you can splice into it. -Ryan |
