2007 Crusader 5.7MPI alternator

Replacing the alternator due to overcharging. Crusader parts book says its part RA097007C. Search by model say same part#. Original has a 4 pin connector at the end of wires out of the back & output & ground on studs.New one has no wires or connector. All connections are on the back of the new alternator. I'm not able to get to the boat until the weekend to look. Is this an adaptor harness ? Or is this the wrong part?
Thanks

Update. Just had someone take a look. It is an adaptor harness. The only one I see in the parts list is for the 100 Amp alternator. I have the 70 amp. Connector pins all look good. I'll just pop the new one in should be good to go.
