OK - Glad you dug into the problem quickly . . . After you get everything dried out, you need to clean and refinish the well areas. I used scrubbing bubbles with bleach to clean it up and then sprayed a coating of DupliColor Truck Bed Liner spray on the metal to seal and protect the entire well area.
You should also get a tube of dielectric grease and apply it generously to all the wire harness connectors on your Central Locking Pump module. It's still likely that you'll have to replace the entire pump module but you might get lucky and be able to save it. There is also a black plastic box mounted near the Central Locking Pump module. That is your towing / security module. You need to take that out and dry it out too. Likely will need to be replaced though.
Next you need to seal up the areas that allowed water intrusion into your trunk wells . . . The wing mounting plate area and the wing mounts themselves are the most likely problem areas.
