I would suggest you spend some time looking at the online micro fiche at someplace like Ronnie's harley parts.

The exploded diagram view shows how all the parts go together

If you have the module and the wiring then its mostly plug and play however you will need the dealer to help the ecm to recognize you have cruise, plus you need the correct hand control, the fairing wiring and the on off switch, correctly cables, etc

The module is just one of the many components that work together. It is not the only component required
