questions

I just finished my motor and drag install and have a couple of questions that i am hoping you guys can help me with. First off when i started the car to let the motor idle and rings set i was watching my newly installed greddy EGT gauge and it is not working. The light is working on it but i am not getting a temp reading. I think it is the ignition wire (orange wire). Could someone let me know where they have it wired in? Next i am running the afc hack until i get my hondata in a couple of wks. Everything is idling and running find, what i need to know on the afc there is a setting where you have to pick the # of cylinders your car has and also the throttle signal. Could someone let me know what throttle signal to use. i would appreciate it .
