No Power For Trailer At Plug In

[zacman]

Hi , I have a 2005 2500H.D. .I'm trying to get power to the "aux. trailer power" terminal on the trailer plug.According to the fuse box/book stud #2 should supply the juice.Stud #1 has a "dummy" (fake) fuse in it but if I switch the two fuses I get power back at the plug in. If i get a real fuse for stud #1 and go with that will I hurt anything else? There is only one red wire going to stud #1. But the box is labled for duel batterys(don't have) or for diesel (n/A). if this is the route to take what amp fuse should I go with?Was this wired backwards at the factory? Thanks for the help.
