First what brake controller did you buy and install?
If it is a Prodigy or not you will have to wait until the trailer arrives and hookedup. At that point you will do some basic setup but you will have to drive and apply the brakes to get it setup correctly.
You basically want the trailer to actually apply its brakes a little mor ethan the truck so it won't go into a slide.
Didn't you get a book or something with your brake controller?
Hope you get your rig soon as I can see you are getting a little wild waiting.
