Need way more information than what's provided.
What builds have you done in the past? What are you looking to achieve from this build? Flavor or Cloud?
What type of wire do you have available? Gauges?
What batteries are you using? Is the build only for your Snow Wolf or do you intend to use it on a different mod also?
Safety is key! When asking for suggestions you need to provide more details please.
The Snow Wolf is a great mod and you can build a ton of options including Temp control Ni200 builds.
