Nitrous plumbing A1A...??..

So here's where I stand now:
I basically have Sunday to work on the car and maybe possibly part of Tuesday but late morning I have to get that shot in my eyeball so I'm not sure how much of that day all I have to work on the car..
Anyways first things first all I have to do is run one wire from the dash under to bottle heater and run a ground to the chassis and connect that up and call that done. I already have a fused switch on the dash and a lead line coming out to connect to for the bottle heater..
Then to the window switch, I'll start by finding a good spot to mount it and mount it. I'll use a line connector to put the red wire to the ignition wire for the MSD. I will ground the black wire and hook the gray wire up to the tach wire. Right now I have the relay ground going to the low pressure switch and coming out of the low pressure switch and grounding next to it. I'll take that ground wire from the low pressure switch and run a wire back into the car and hook it up to the blue wire on the window switch...
So now in order for the nitrous to work I will have to open the nitrous bottle I don't have to purge it but I will. I will have to turn on the fuel pump for the nitrous and I will have to arm the nitrous by turning on the switch that gives the button on the shifter power. I will have to hit the button on the shifter be at full throttle to trigger that switch and the fuel have to be up to 5 lb of pressure or more to trigger the ground for the relay and it will have to be in the set window on the window switch to complete the ground for the relay..
And don't forget columbo! And just one more thing LOL Wednesday I'm supposed to get the new nitrous filter. once I screw that on and get all the said stuff done I will have ran out of excuses...
