Hopefully when I get back from snowmobiling today I'm going to finally make my order. Should be two nitrous plates and two longer 14 inch hoses as I'm not going to do the one short one and one small one on each solenoid. I'm going to try and do it right and Deuce two smaller ones on the fuel into longer ones on the nitrous oxide. Also since I sent that Speedmaster junk back I'm buying a couple small solenoid brackets.. I'm going to first get all the hard parts for around the carburetors. I already have my nitrous feed line. The next I want to build the fuel system. Then the next plan is to wire everything all into switches. At that point if I have a retard I will use it. The very last thing I'm going to do is buy a nitrous bottle and have it filled. And mount it... LOL.. but the big swap meet is here in about six weeks so I may try and look for a bottle there or some other accommodating parts. After the Speedmaster junk part syndrome my wife is on board with me getting good new parts for such an elaborate operation with its potential to make the motor go KAPLOOEE...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.
