Yes those can be used. Hopefully when they send them to you ,you'll get a wiring diagram!!
No diagram!! you'll need to read each wire as to what gets powered when you change switch position!!
The way I do this , hook a LOW amp battery charger leads to the wiring of the switch,, USUALLY RED wire is power and groung to the switch housing, then just chase wires 1 at a time and label.
Since this switch is for XS650 you'll have to remove the connector that plugs to the bikes wiring and rewire seperately..
GOOD LUCK
try using this as a base
