Posted on nebraska-subaru.com regarding your wiring harness:
I've purchased parts from Jamie Thomas at subarugenuineparts.com in the past and have always been very happy. Send her an email and see if she can help you out email@example.com. I didn't find it doing a search of the catalog, but Jamie should be able to find it.
I did a search of another online site (no idea if they are good to buy from) and found it for $239.
