Talked to FAST, and they said this pin is used to power all 5v sensors. Instead of accessing C24 for my 5v supply, I will just use the 5v at the TPS for my signal. According to ZEX, there is not any concern, as the draw from the nitrous controller is very minimal.

Thanks for your input. I think I have settled on using the ZEX kit the way they designed ie, triggering the NOS with WOT TPS voltage. The boost turn off point is fully adjustable, so I will off it at 10 psi (for now) and let the Deeds control launch boost from that point. I will however use the FAST to control the minimum RPM at which the nitrous can spray. At this point, I will use Aux 1 (pin B1) to turn on the juice @ 2,600 via a relay in the arming switch. This NOS stuff definitely reqires a learning curve.

Jack---did you get my pins for the XFI?
