quick wiring question

im trying to wire up my turbosmart single stage boost controller and there is two wires coming out of the unit that are fairly short, the brown is ground and teh blue is positive. there is another long set of blue wire that came with not attached, it says im supposed to wire the blue wire through the switch that came with and to a 12 volt ignition supply… does this mean i hook up the blue wire to the short blue wire from the unit and hook the other end straight to the on part of the switch, and take the rest of the blue wire fron the igniton supply to the off part of the switch? i think thats how it goes but not totally sure… i was really wondering what a 12 volt igniton supply would be and where, im not totally good at the wiring stufff.

thanks drew

a 12 volt fused igniton supply i meant sorry.

Do you not have any aftermarket gauges or an afc that you can spllce into its power?

Or maybe use the stereo? ( There are a few options)
