Nitrous plumbing A1A...??..
Here's one of the hand drawn schematics I keep on my phone of my nitrous system's current configuration.
MSD 8969 digital window switch
MSD 8982 start/retard control
The retard box takes pills, I prefer that to the dial type adjustment that might accidentally get "adjusted".
The system automatically retards whenever the nitrous solenoids actually get energized.
On the left side is the 3 position switch that arms the nitrous...
...bottom position- full advance / nitrous off
...middle position- retard on / nitrous off
...top position- retard automatic / nitrous armed
Advance in the distributor is locked, I use the middle position to pull some timing manually if the engine needs to be calmed down a bit for low speed driving.
The little box marker "timer delay" is for the nitrous hit delay. This pic only shows the switched contact part of the relay, I have another pic that shows the actual wiring of that box.
