Orangejohn, you should be fine. The problem seems to arise when the connector is not pushed fully home and making good connections. You are so right to check it and make sure that the cavity is clean and no water in there. Probably fill with vasaline or similar and make sure that it is fully home. I had the original problem and since a new loom was fitted I have had no more problems.
Not to self, check the connection this weekend!
