You need the correct wiring. Every make uses different wiring and even the same bike in different years can have different wiring.
That thing though shouldn't be too complicated and if you got a wiring diagram it should be possible to make a wiring loom I'd think... well I certainly could.. but I've been rewiring bikes for fifty years haha.
