Power Grid 7730 controlling Nitrous

[Rkorrow]

Currently have NOS Profogger being controlled from Transbrake and Full throttle switch. I want to use the 7730 RPM/Timing switch to give me better control over release. I'm looking for feedback on options and where to introduce the relay. I'm thinking I have these options:
1 - Remove Transbrake relay and use 7730 output switch after the full throttle relay.
2 - keep Transbrake and just add the 7730 output switch. Not sure where?
3 - Don't use 7730 output switch.

here is an example of a 7730 with 2 stages and the brown/white controlling the second stage.
