I think you'll have the old-style neutral light switch, which uses two wires with those wires being permanently attached to the switch.
Neutral light switch - no. 6
The later switches, like on my Evo, have just one wire, which is easily removed from the switch via a bullet connector.
It's a bit more complicated to remove the old-style switch as the wiring gets in the way of a socket.
It's a long time since I owned my 900 but, from (an increasingly hazy!) memory, I would use a box spanner after disconnecting the switch from the loom and feeding the wire up through the box spanner.
