it will work both ways, on some circuits in cars the ground connection is relayed. i added a diagram how to wire it the other way around too.
In bokeys schematic, the connection to the right of the switch must be a + source, not ground for it to work, OR both connections to the left of the relay must be +
heres one with the switch to a ground....
