Wire up Heat to single switch
 

So i have made a new center console for gages, switches, and other things i wanna add. Well in my line of switches i need my heat. I was hoping someone could help me find a way to have my heat work just full blast, full heat with 1 switch. I read my rx7 parts / diagram layout book but cant really figure it out. In advanced Thanks!
