      Because gauges do not pull much power, you can easily hook up power for one gauge, or even two with this expandable circuit kit.

    What circuit in the fuse panel do you recommend? Is there more than one?

      We do not have a preference for which fuse to tap into. In the fuseblock, all of the connections have the same available amperage, its the fuse that limits the power. So, you can use any of the fuses you prefer.

    Could this add a circuit be used to wire a Nitrous kit? Could I use this to wire the arming switch, purge button and bottle heater switch?

      This is used for small power draw items (normally gauges and other light electronics). If you only need power to illuminate the switches, sure thats fine, but if you are wanting to control solenoids, and or heaters which would draw way more power, then you should find a way to connect those to the battery through a proper relay and fused connection.
