Speed lab has those in stock. They also ordered around 50 liquid level switches so they will have plenty., They also have all the nozzle sizes in stock plus I will be bringing some extras with me. You will want the 1gph nozzle since you have a 3GPH on the vehicle already.
You will get a very nice change in throttle response and have instant spool time on the turbo, It's basically like adding a larger turbo
I won't be able to bring there full order with me because I'm only one person, and it's about 700 kilos worth of stuff lol.
Glad to hear your enjoying the system. They will have the switches in stock on Saturday
