I knew I'd seen that...part number is 50462-323-000, called protector, ignition. But I'm not sure yet just where it goes without going out to see my bike. That's not happening till the temp goes back above 10 degrees F!
Ok, it's number 11in the general export wire harness fiche at cmsnl
I think it attaches to the top of the front coil mounting bracket, but I'm not sure about that placement.
