I think I will have to stop in at a RV place to get the electrical components (plug mostly)
What amps did you wire your trailer for? I was thinking 30amps would be more then sufficient and then have a small breaker box and have my first outlet being GFI. I am lucking out though since my BF is wiring his garage this weekend with a co-worker that does electrical work so I might be able to sneak the extra wire for my trailer...
I also did find this website http://todd.redwrench.com/Electrical.htm
which is a good step-by-step on finishing a trailer- even though mine wont be near that nice :)
