I need to know how to wire it up so that when i'm on the transbrake the switch is off and when i release it, the spray comes on!
I would utilize a Single Pole Double throw relay such as this http://www.oznium.com/relay40 Connect 30 Power Source 87a Nitrous system 87 Transbrake 86 Ground 85 to Transbrake switch Please keep in mind that you will still want a arming switch for the Nitrous system as power will be availble to the 87a terminal at all times unless the Transbrake switch is pressed then power flows to the 87 terminal.
