Surprise!

I've found a few surprises in Buttercup like an old McDonald's toy and a screwdriver, but this one beats all that.  Look what I found!

I was laying down new carpet (more on that later), removed the quarter panel cover in the cargo area and looked down and see a relay and this trailer plug.  Looks like the PO just ran it out the tailgate.  As much as I'll use it, I will probably do the same but going to look out for some good gaskets I can run it out through (without getting water and dirt back in).  This is one less project marked off the list!
