Default Wire numbers on instrument panel

I have a 2005 1800SR3 which has numbers on the wires on the instrument panel. Planning to replace the ignition switch and would like to find out if there is documentation detailing the wire numbers. Ignition wires are marked 1, 2, and 3.

Try looking up,it has a wiring diagram.

Ignition switch should be marked "B" battery, "I" ignition, "S" start, make a drawing of the back of the switch with wire numbers.
