my set is purge kit and wet system 100 Shot but I'm having trouble on what pin to tap into? I've read J1 52, J1 53, J2 56, but nothing for certain... and what to do with the wire once I'm tapped into the pin? do I hook it up to the N20 activation switch? any help is appreciated.

Pin 56 (On the Green or Red connector) should not have a pin in it. If you have a wire from another PCM, you can just pop one in. Connect this wire to a switch and that switch to ground. When you ground this pin, it will use the N2O/valet tables.

appreciate the help thanks... so the wire from pin 56 should it go to the activation switch for the N20 or a separate switch just for the PCM?

Do you want the COS#5 N2O functions to be used with the N2O activated only or from the point that you arm the system? 11756 Picture from the EFI_Live tutorial

I wanted to only be active when I turn the activation switch on
