There is a possibility of getting just the connector body, but obtaining the part number would probably be easier through viewing the wiring schematics. If you view the portion of the schematics that portrays the pinout location it gives you a part number for the connector body and also your terminal part numbers. The terminal part numbers are not in the typical parts system, but the connector part number usually is if it is available. If there is much chance of getting the connector, it would be either that way or speaking to a parts guy and seeing if the parts catalog lists a number for that harness assembly. The actual parts catalog does list far more than you can find online so there is at least a chance. Your best bet would be to physically go to a dealer parts department and look at the parts fiche with the parts guy.
