I was just looking around and couldn't find much of anything in regards to a dual bottle NOS system where they both open at the same time.

Is it possible to have two bottle valve openers that open with the same switch?

How would I wire all of this, does anyone have a wiring diagram?

Please let me know what you think is the best way to wire this all up.

You really have nothing to gain by doing that but you would simply follow the instructions on wiring up a bottle opener then tie into those same wires with the second opener.

You won't have any issue wiring both openers to one switch.

the reason you run 2 bottle is to have more nitrous volume available which reduces the amount of presure drop you see during a run. The down side is it takes longer to get bottle pressure back up.
