When we had our trailer, I purchased and installed a Prodigy P3 brake controller. Not difficult to install and costs around $125 or so.
I don't know if you have a Freighliner chassis or not, but if you do, they have been providing a harness with their chassis for several years now. Monaco use to do the same thing. Not sure if any other mfg'ers did or not.
Good luck
Ron
