FS Tow-Ready trailer wiring kit for 2005 Subaru XT (Western MA)

I have a never installed trailer wiring kit when I bought my 2005 Subaru XT because I bought a log splitter in NJ and found out I didn't need lights for it because it didn't block the brake lights. I had the intention of buying a trailer but never did.

So, I have a new in-box Tow Ready adaptor kit for it that I have opened (to check out the instructions) but have never used. (See attached pictures).

It is Tow Ready part#118370. I have checked towready.com's website and it appears the model# for my subaru has changed and I'm currently inquiring about what the difference is. (they seem to have a different model# when I look up a 2005 Subaru.

Looking for $20 and shipping just to take it off my hands..
